Call

Thrombosis of hemorrhoids is a complicated stage of chronic hemorrhoids. The disease develops due to impaired bleeding. Blood clots form in the structure of the cavernous vascular plexuses. The acute process lasts for a week. After this, the thrombosed node is replaced by connective tissue. In the absence of timely treatment, necrosis of ulcerative formations on the intestinal mucosa develops.

As a result, complications arise: a blood clot that formed earlier blocks the vascular lumen and prevents the reverse flow of blood from the nodular protrusion. This is why blood clots occur.

Depending on the location, the following types of hemorrhoidal thrombosis are distinguished:

  • interior;
  • outer;
  • combined;

Proctological pathology is classified into three degrees of severity, which have different etiologies, symptoms and neglect.

Briefly about the main thing

Thrombectomy is a minimally invasive (low-traumatic) operation that is performed to eliminate a blood clot formed in hemorrhoids.
This intervention is performed for acute hemorrhoids. Thrombectomy is performed under local anesthesia and takes no more than 10 minutes . The procedure has the shortest list of contraindications and does not require hospitalization of the patient. You can go home immediately after surgery .

The recovery period passes quickly and is not associated with serious restrictions. It will be necessary to follow basic hygiene rules: wash the anal area with warm water after each bowel movement. You should also follow all the doctor’s recommendations: ___• follow a diet, ___• limit physical and nervous stress, ___• avoid excluding thermal procedures, ___• take prescribed medications, ___• carry out local treatment of the postoperative wound.

Causes of thrombosis of hemorrhoidal veins

Thrombosis can develop as a consequence of an acute, first-time attack of hemorrhoids, as well as as a complication of chronic hemorrhoids. The likelihood of developing thrombosis in chronic pathology increases with increasing “length” of the disease and the size of the nodes.

An attack can be triggered by: ___• chronic stool disorders (constipation, diarrhea, constipation alternating with diarrhea), ___• increased physical activity, ___• labor, ___• consumption of spicy food and/or alcohol, ___• hypothermia, overheating.

The development of acute hemorrhoids is promoted by all conditions accompanied by an increase in intra-abdominal pressure - from pregnancy to chronic cough and obesity.

Another factor in the occurrence of hemorrhoids is stagnation of blood in the veins of the pelvis, which often occurs as a result of a sedentary lifestyle and “sedentary” work.

Mechanism of blood clot formation

Thrombosis of external hemorrhoids occurs more often. It is extremely rare that the process spreads from external to internal nodes. Even less commonly, it occurs isolated in internal nodes.

Thrombosis of the external hemorrhoid occurs in both acute and chronic processes. In both cases, the pathology develops as a result of a combination of three factors: ___• slowing blood flow in the node, ___• blood thickening, ___• damage to the vascular network of the hemorrhoid.

Signs of thrombosis

___• The main symptom of thrombosis is acute, excruciating pain that prevents normal bowel movements. The pain syndrome intensifies many times over with straining, movement, and also in a sitting position. In severe cases, the pain takes on a pulsating character and, depending on the location of the node, can radiate to the leg, inside the rectum or to the external genitalia. ___• Bleeding often occurs, which varies in intensity - from individual drops on the surface of the stool to a trickle of blood during bowel movements. ___• Thrombosis of the internal node causes the sensation of a foreign body inside the rectum. Since the bleeding injured node comes into contact with feces, a secondary infection may occur. In such cases, mucous or purulent discharge appears and body temperature rises.

Hemorrhoidal thrombosis - symptoms and treatment

Acute hemorrhoids is a disease, with adequate treatment of which, in 98 - 100% of cases, complete relief from the manifestations of thrombophlebitis is possible.* With conservative management of an exacerbation after the signs of inflammation subside, the disappearance of edema, further treatment of hemorrhoidal disease is indicated using numerous methods (minimally invasive: latex ligation, sclerotherapy, laser vaporization or classic hemorrhoidectomy). Correcting changes in chronic hemorrhoidal disease is necessary, among other things, to exclude relapses of thrombophlebitis of the nodes and improve the quality of life.

The choice of method for removing pathologically altered cavernous plexuses in chronic headache depends on their location, size, degree of dystrophic changes in the underlying tissues (stage of the disease), the availability of modern medical equipment in the medical institution and the surgeon’s preferences.

Prevention of the disease consists of eliminating factors that provoke exacerbation of hemorrhoidal disease:

  • Normalization of stool;
  • Drinking enough fluids throughout the day;
  • Increasing physical activity**, combating physical inactivity;
  • Nutrition correction - increasing the diet of plant fiber, vegetables and fruits, fermented milk products***;
  • Limiting the intake of strong alcohol and spicy foods;
  • Treatment of chronic inflammatory processes in the perianal area (proctosigmoiditis, chronic hemorrhoids);
  • Reducing body weight to optimal parameters (BMI 20-23);
  • Treatment of concomitant diseases - arterial hypertension, diseases of the gastrointestinal tract.

*if in complex therapy surgical aids with coagulation of the vessels feeding the node were used.

**dosed physical activity helps normalize weight, metabolism, and strengthen the pelvic floor muscles. However, they should exclude activities that lead to a sharp increase in intra-abdominal pressure (deadlifts, squats with loads, weightlifting, powerlifting).

***if diet correction is not enough, for persistent constipation, regular use of probiotics and prebiotics, laxatives - lactulose (Lactusan, Duphalac), oval plantain seeds (Mucofalka, Fitomucila) is appropriate. Typically, the side effects of lactulose - bloating, flatulence - are eliminated by reducing carbohydrate intake, which prevents excessive growth of intestinal microflora.

Prevention of acute hemorrhoids in pregnant women

Even at the stage of pregnancy planning, girls need to consult a proctologist, because in the presence of hemorrhoidal disease, stage 1. manifestations may be minimal and unnoticeable to a young woman. However, when carrying a child, all minor problems can become quite painful for the expectant mother, and their effective treatment during pregnancy will be extremely difficult.

Repeated examination of pregnant women is indicated in the 2nd–3rd trimester. Even before the onset of birth, some pregnant women experienced some degree of exacerbation of hypertension, which is associated with impaired venous outflow from the pelvis, an increase in intra-abdominal pressure and changes in blood coagulation parameters. And during natural childbirth, thrombophlebitis occurs in almost half of women in labor due to direct compression of the nodes by the fetal head passing through the birth canal.[13]

For natural delivery, the diagnosis of hemorrhoids is not a contraindication, but the condition requires dynamic monitoring by a specialist and the implementation of certain recommendations.

When is thrombectomy necessary?

Indications for surgery

Most cases of acute thrombosis of hemorrhoids (uncomplicated thrombosis, small size of the node) respond well to treatment with conservative methods. The main thing is to consult a doctor in a timely manner.

Surgical procedures are performed if the period from the onset of the disease is 48-72 hours. If more time has passed since the onset of thrombosis, the doctor prescribes conservative treatment followed by surgical treatment. Surgical removal of a thrombosed node is carried out at a later stage from the onset of the disease in the following cases : ___• conservative therapy was unsuccessful, ___• acute pain syndrome, poorly controlled by standard painkillers, ___• symptoms of intoxication (general weakness, fever, headache), ___ • contraindications to the use of thrombolytic agents (pregnancy, lactation), ___• large size of the hemorrhoid.

The decision on surgical intervention is made by the doctor after an examination, which will reveal contraindications to surgery. Another goal of diagnostic manipulations is the choice of surgical intervention method.

Why is thrombosis dangerous?

Firstly, thrombosis never resolves on its own. The longer you delay treatment, the worse the pain.

Secondly, over time, tissue necrosis can occur when thrombosed nodes fall off and ulcers form in their place. The ulcers gradually increase in size, and purulent paraproctitis develops, the treatment of which may require serious surgery.

Don’t delay in contacting a proctologist! In most cases, hemorrhoidal thrombosis can be cured in 1 visit to the doctor.

Types of operations

Removal of a blood clot for external hemorrhoids

Removing a blood clot for external hemorrhoids is a simple operation that lasts only a few minutes. The doctor makes a small incision over the blood clot. Then the blood clot is removed with tweezers or a clamp; the wound is not sutured. The inflammatory edema subsides almost immediately, the pain subsides, and the patient’s general condition improves.

According to indications, a more complex operation can be performed - excision of an external hemorrhoid with blood clots , which is also performed under local anesthesia and does not require the patient to be hospitalized. During excision, the pathological element is removed, which reduces the risk of recurrent thrombosis.

Removal of a blood clot for internal hemorrhoids

Thrombosis of internal hemorrhoids is much less common and, as a rule, develops in the later stages of the development of the process (III-IV stages of hemorrhoids).

Treatment in this case is conservative. After stopping the acute process, treatment is carried out aimed at removing internal hemorrhoids (hemorrhoidectomy).

Causes of thrombosis

Intestinal thrombosis occurs as a result of atherosclerosis of the mesenteric vessels. A plaque forms in the artery, which narrows the lumen and impedes blood flow. In the worst case, the vessel is completely blocked, and as a result, the blood supply to any part of the intestine is disrupted. The affected area does not receive normal nutrition, as a result, destructive changes occur in the intestinal wall. This process begins from the mucous membrane with the appearance of ulcers and necrosis. Then the tissue disintegrates and the intestine perforates, that is, a hole is formed in it through which the contents of the intestine enter the abdominal cavity. In this case, peritonitis develops, which can lead to death.

The causes of intestinal thrombosis may be the following:

  • atherosclerosis;
  • hypertonic disease;
  • heart defects;
  • heart attack;
  • cardiosclerosis;
  • obliterating endarteritis;
  • liver and spleen diseases;
  • abdominal trauma;
  • malignant tumors;
  • complications after surgical operations on the abdominal organs.

Diagnostics

Diagnosis of hemorrhoidal thrombosis is not difficult. The diagnosis is made by external examination of the anal area .

If the proctologist decides on surgical intervention, it will be necessary to take tests : ___• general blood test, ___• coagulogram, ___• blood glucose level.

It is necessary to tell the attending surgeon about all medications taken, since some medications (oral contraceptives, non-steroidal anti-inflammatory drugs, etc.) affect blood clotting.

Diagnosis of thrombosis

The examination is carried out in the most comfortable position for the patient!

A comprehensive diagnosis is carried out for a more complete and in-depth study, allowing you to see the full clinical picture of the disease:

  • Digital examination of the rectum
  • Hardware diagnostics Videoanoscopy
  • Video sigmoidoscopy
  • Consultation with a doctor to make a diagnosis.
  • Depending on the clinical symptoms and complaints (for example, a complaint that the anus is itchy), the proctologist may prescribe additional examination methods.

    Contraindications

    ___• The operation is not performed if the patient’s condition is extremely serious (general exhaustion, complications of cardiovascular diseases, sepsis). ___• Surgical interventions are not prescribed for severe pregnancy (severe anemia, poorly controlled early toxicosis with dehydration, late toxicosis with generalized edema, etc.).

    Since thrombectomy is a minimally invasive (low-traumatic) operation, the procedure can be prescribed after the patient’s condition has been stabilized. The decision about surgery or its inadmissibility is made individually, taking into account all risk factors.

    Preparation for the procedure

    If the doctor decides to undergo thrombectomy, the patient is prescribed a diet that excludes foods that cause gas formation in the large intestine (cabbage, legumes, fresh fruits and juices from them). The ban also includes products that cause a rush of blood to the rectum and/or have an irritating effect on the mucous membrane (smoked meats, spicy foods, alcohol).

    Immediately before the procedure (in the morning and evening before the operation), you will need to cleanse the intestines using a Microlax microenema.

    Preparation for thrombectomy is carried out when the patient's condition allows it. In case of severe pain and an impressive size of the node, bowel cleansing is not performed, and in the event of a threat of severe complications, surgical removal of the blood clot is carried out on an emergency basis.

    Clinical manifestations of thrombosis of external hemorrhoids

    The main complaints of patients in this category include: the appearance of protrusion (“bumps”) in the anus. The size of these neoplasms can vary and is accompanied by hyperemia and swelling of the surrounding tissues. In most cases, their appearance is accompanied by intense pain. The severity of pain can be determined using special rating scales. The method of further treatment will depend on this assessment. If the number of points is more than seven, then surgical treatment will be required. If up to four points, then you can get by with conservative methods of treating thrombosis of the external hemorrhoid .


    thrombosis of the external hemorrhoid

    During the act of defecation, a significant increase in pain can be noted, as well as when sitting. The swelling and pain can be unbearable. The severity of the pain will depend on the size of the blood clot. The duration of the disease is on average about two weeks, but may be longer. Also, a blood clot can occasionally be evacuated from a hemorrhoid on its own. And this happens after necrosis of the inflamed area, when the blood clot itself comes out through the area of ​​tissue damaged due to necrosis. At the same time, you will notice a slight discharge of blood. Pain, swelling and the entire inflammatory process will begin to subside after this. But the process of necrosis may not end there, but may move on to the hemorrhoidal node and nearby tissues.

    Therefore, in any case, consultation with a specialist is necessary. Even after thrombosis subsides, “fringes” of tissue remain in the affected area, which can cause some discomfort, although they themselves do not pose a threat.

    How is the operation performed?

    The procedure can be performed in a gynecological-style chair or on a couch and takes a few minutes. First, doctors give an anesthetic injection that “freezes” the tissue, just like in a dentist’s office. Therefore, the patient is conscious, but does not feel pain.

    The surgical intervention takes several minutes and involves three manipulations: ___• opening the affected node (small incision), ___• removing the blood clot, ___• stopping the bleeding (the wound can be sutured, but more often it is not sutured)

    After the procedure you can go home.

    The exception is those cases of thrombosis when severe complications occur (gangrene of the node, paraproctitis, severe bleeding) that require hospitalization.

    Rules of behavior in the postoperative period

    If the evacuation of hemorrhoidal blood clots was carried out against the background of the patient’s satisfactory condition, then the postoperative period does not provide for significant restrictions.

    The following are prohibited: ___• physical activity, ___• thermal procedures (bath, sauna, beach holiday), ___• prolonged stay in a sitting or squatting position.

    Products that cause a rush of blood to the pelvic vessels or irritation of the mucous membrane are excluded from the diet: spicy, salty, smoked foods and alcohol.

    Food should be rich in fiber, which stimulates intestinal function (prunes, apples). It is not recommended to eat foods that can cause constipation (rice and semolina porridge, potatoes, pasta). If stool retention occurs, a mild laxative (for example, Forlax) is prescribed.

    After each bowel movement, wash the anal area with warm water and change the sterile napkin. If suspicious symptoms appear (pain, bleeding, discharge from the wound), you should immediately consult a doctor.

    Main features

    Most often, arterial thrombosis begins acutely. The prodromal period (the initial stage without obvious clinical symptoms) is characteristic exclusively of arterial thrombosis. In this case, for about 1-2 months the patient complains of periodic abdominal pain, bloating, vomiting, nausea, pain after eating, and unstable stool. The cause of these symptoms is vasoconstriction due to thrombosis or atherosclerosis.

    Venous thrombosis develops over several days (two to five). At the onset of the disease, there is a slight increase in temperature and unexpressed abdominal pain of uncertain localization.


    Intestinal ischemia

    The main symptom of intestinal thrombosis is severe pain. They are especially unbearable in the initial stage of the disease - ischemic, which lasts from 6 to 12 hours. Patients, as a rule, cannot find a place, scream, and pull their knees to their stomach. The pain is not relieved even with narcotics. Some effect can be obtained from antispasmodics.

    In addition, the following symptoms are noted:

    • pale and bluish skin;
    • rare pulse;
    • increased blood pressure.

    At the same time, the stomach remains soft and the tongue moist. A blood test shows that the number of white blood cells is increased. The pain is concentrated in the epigastric region or throughout the abdomen. Symptoms such as nausea and vomiting occur; most patients experience loose stools mixed with blood; a quarter of patients experience stool retention.

    After 6-12 hours, the infarction stage begins. It can last up to a day. During this period, the pain subsides somewhat due to the death of pain receptors, which occurs as a result of necrosis of the intestinal wall. Patients calm down, but due to intoxication their behavior becomes inadequate. The pulse quickens, the blood pressure returns to normal, and the number of leukocytes continues to increase. The pain is localized in the area of ​​the affected areas.

    18-36 hours after the onset of the disease, the stage of peritonitis begins. Inflammatory processes in the abdominal cavity lead to increased pain during palpation, coughing, and body movements. The general condition of the patients deteriorates sharply, which is due to dehydration, toxicosis, metabolic acidosis, and electrolyte imbalance. Pain is felt throughout the entire abdominal cavity. In this condition, the patient experiences symptoms such as dry tongue, gray skin, thready rapid pulse, low blood pressure, high leukocytosis.

    In the case of arterial thrombosis, if timely assistance is not provided, the course of the disease lasts two days, then death occurs due to intoxication and peritonitis. With venous, the process lasts five to six days.

    Reviews from patients and recommendations from doctors

    We analyzed online reviews of patients who underwent removal of hemorrhoidal thrombosis. The vast majority of patients were satisfied with the procedure. The most common impression: “The procedure itself is not as unpleasant as waiting for it.”

    No reviews of complications of the operation were found. The most common complaint is pain in the area of ​​the postoperative suture, which disappears after a few hours, but may reappear during bowel movements.

    A more serious drawback is the likelihood of relapse. In order to avoid recurrent thrombosis, you must follow all the recommendations of your doctor.

    Symptoms

    Determining the external type of the disease is difficult because the symptoms are smooth, but the symptoms of thrombosis with the internal location of the hemorrhoid are pronounced. These manifestations can be defined as follows:

    • Feeling of burning and itching in the anus. Discharge is possible, especially after defecation (from straining).
    • The presence of blood in the stool - at first scanty, then abundant.
    • The occurrence of an attack of acute pain in the anus (not associated with the process of emptying).
    • Prolapse of hemorrhoidal cones that cannot be reduced.
    • Swelling of the skin near the anus, gradually spreading to the groin area and accompanied by severe pain.
    • Painful sensations not only when making movements, but also at rest.

    Symptoms intensify as the disease progresses. Normal touching of the skin becomes unbearable as the inflammatory process spreads. Thrombosis of the hemorrhoidal node is visible externally (when examined by a specialist). The hemorrhoid often becomes purple in color, and necrotic areas of the skin are noted. If enhanced measures are not taken to treat the patient at this stage, a rupture of a thrombosed hemorrhoid with heavy bleeding or purulent paraproctitis may occur.

    Advantages and disadvantages of the method

    Thrombectomy is a low-traumatic method of treating acute thrombosis of hemorrhoids, which has both advantages and disadvantages. The method involves surgical intervention, so it is prescribed if conservative methods are contraindicated or ineffective.

    Positive aspects of thrombectomy: ___• a short list of contraindications, ___• does not require hospitalization, ___• the shortest recovery period with a minimum number of restrictions, ___• minor side effects of the operation (pain, weakness, swelling), ___• complications are extremely rare.

    Disadvantages of the method. Thrombectomy does not involve removal of the hemorrhoid, so recurrent thrombosis may develop. For this reason, in case of recurrent thrombosis, a more radical operation to remove thrombosed nodes (hemorrhoidectomy) is indicated.

    What is acute perianal venous thrombosis?

    The size of the blood clot and the severity of pain are the main factors that determine the choice of a doctor. Moreover, many doctors believe that there is a relationship between the size of the blood clot and the intensity of pain. Most likely, this issue requires additional research in order to determine all the factors that cause pain, for example, the characteristics of the patient’s nervous system, etc. The severity of pain, as a factor determining the choice of treatment method, does not appear in domestic recommendations, however, practicing doctors, through their clinical experience, have come to understand its importance. It is in patients with pain syndrome of 8-10 points on the visual analogue scale that it is logical to expect the maximum difference in pain before and after surgery, even if after surgery the pain is 4-6 points.

    The duration of the disease had a very big influence on the choice of our colleagues, in fact, as indicated in the recommendations. Doctors prefer conservative treatment, regardless of the patient’s complaints, in pregnant women and in patients over 70 years of age. But almost 30 years ago Saleeby RGJr. proved that surgical excision of thrombosed nodes in pregnant women quickly relieves symptoms, is less often accompanied by relapse, and there is no risk for both the mother and the fetus.

    Prevention of relapse

    Basic principles of prevention

    Thrombosis of the hemorrhoidal node occurs as a complication of hemorrhoids, therefore, prevention of relapse consists in preventing the occurrence of enlarged hemorrhoids.

    Hemorrhoids are a disease with a hereditary predisposition. Therefore, if there has already been one attack, there is a high probability of relapse. However, the implementation of a negative scenario is possible in the presence of additional risk factors: ___• pregnancy, ___• taking hormonal drugs, ___• overweight, ___• constant diet violations: eating spicy and fatty foods, alcohol, ___• abuse of thermal procedures (bath and sauna) or regular hypothermia, ___• work involving prolonged sitting or heavy physical work.

    Necessary precautions

    Most often, acute thrombosis occurs as a consequence of prolonged bowel dysfunction (chronic constipation). Therefore, you need to achieve daily bowel movements with a diet rich in fiber.

    It is advisable to refrain from physical and nervous overload, as well as from hypothermia and overheating of the lower half of the body. You should not abuse alcohol, as well as spicy, smoked and salty foods.

    When working “sedentarily”, you need to take regular breaks, during which you should perform hemorrhoid-preventing exercises. Many chronic diseases can contribute to the development of hemorrhoids, so taking care of your health is a reliable prevention of thrombosis of hemorrhoids.

    Dangerous for the development of hemorrhoids and obesity. With this pathology, intra-abdominal pressure increases, the rheological properties of the blood change, problems with stool arise, and hormonal levels are disrupted. Therefore, normal weight is not only beauty, but also health.

    Detection methods

    Thrombosis can be determined by a medical specialist through diagnosis, but the patient himself must be attentive to his health (especially for the external type of the disease).

    Diagnostic methods:

    • visual examination (on your own, with the help of loved ones or with the participation of a doctor);
    • digital examination of the rectum (done by a specialist);
    • use of modern equipment (anoscope, rectoscope, etc.).

    Externally, the nodes look like violet-bluish formations, and when pressed on, their volume may decrease. There may be black inclusions – necrotic areas.

    After palpation, it is possible to see traces of blood on medical gloves; formations inside the rectum bleed; upon contact with them, the patient complains of severe pain.

    Examination of the rectum and anus using special devices can give the most complete picture of the disease and make a diagnosis of thrombosis.

    Is it possible to do without surgery?

    If doctors recommended thrombectomy of the hemorrhoid, this means that conservative therapy is not indicated in your case. You should not try to treat thrombosis with “traditional” methods.

    If treatment is inadequate or absent, complications may develop: ___• bleeding, ___• gangrene of the node, ___• paraproctitis (purulent melting of peri-rectal fatty tissue).

    In some cases, the affected node may open on its own and free itself from the blood clot. At the site of the “bump,” a fold of skin is formed – an anal fringe, which causes unpleasant sensations (itching, weeping) and is an unpleasant cosmetic defect.
