What is a recurring anal vein thrombosis?
A recurring anal vein thrombosis is a painful swelling in the area of the anus caused by a blood clot (thrombus) in the external veins of the anal canal and occurs repeatedly. The affected veins are located outside the sphincter muscle and belong to the so-called perianal venous plexus. A thrombus can cause the vein to become blocked, leading to pain, swelling, and possibly bluish-purple discolored lumps on the anus. If the anal vein thrombosis keeps recurring, the typical, suddenly very painful symptoms of an anal vein thrombosis also reappear. These include pain at the anus, swelling at the anus with bluish-purple to reddish discolored nodules, but also anal itching or anal burning as well as a general feeling of tension, stretching, or a foreign body sensation at the anus.
Why does an anal vein thrombosis keep recurring?
An anal vein thrombosis can recur after healing. In medicine, this is called a recurrence. Recurrent or repeated anal vein thromboses can be due to several factors. Besides the factor of genetic predisposition to weak vein walls, chronic strain on the pelvic floor plays a central role. Lifting heavy loads, prolonged sitting, or straining during bowel movements can stress the veins in the anal area. Dietary habits and your lifestyle also play a significant role in identifying causes. A low-fiber diet, lack of fluids, and little physical activity can lead to constipation and thus increased pressure in the anal area, which in turn raises the risk of perianal thromboses. Constipation, as well as chronic diarrhea, lead to increased pressure in the anal area, which promotes the development of anal vein thromboses. Pregnancy is also considered a possible trigger for recurring anal thromboses, as the weight of the growing baby puts pressure on the pelvic veins.

What to do if an anal vein thrombosis keeps coming back?
If anal vein thromboses repeatedly develop, or if there are persistent or very severe pains, bleeding due to sudden rupture of the thrombus, you should definitely see a doctor. The doctor can perform further examinations and assess whether additional measures for treatment of anal vein thrombosis are necessary and recommend an individual treatment and prevention strategy. Read more here about the diagnosis and examinations of anal vein thromboses by a doctor.
What treatment for recurring anal vein thrombosis?
Even with recurring anal vein thromboses, treatment primarily depends on the severity of symptoms and the individual course of the anal vein thrombosis. There are both conservative treatment options and a surgical therapy approach via incision or excision. If a perianal thrombosis recurs frequently and conservative treatment is ineffective, the venous perianal blood clot and the affected tissue are surgically removed by excision. Read more here about the general treatment of anal vein thromboses, as well as about surgery for very large or painful ulcers on the anus. A proven approach in conservative treatment to reduce tissue swelling and support the healing process after colorectal surgery is the treatment of anal vein thrombosis with suppositories.
Conservative treatment for recurring perianal vein thrombosis
For conservative treatment of recurring anal vein thrombosis, painkillers, suppositories, or locally anesthetic ointments are often used to relieve pain. The treatment of perianal thrombosis usually involves decongestant measures such as suppositories, ointments, or sitz baths. These can often lead to rapid relief of the painful symptoms of anal vein thrombosis. Sitz baths with anti-inflammatory additives (e.g., chamomile) can also promote blood circulation and relieve pain at the anus. Certain creams and ointments containing heparin or cortisone can help dissolve the blood clot faster and reduce inflammation or swelling at the anus. As part of conservative treatment, adequate fluid intake and a balanced diet with sufficient fiber are essential pillars of treatment to regulate bowel movements and minimize pressure in the anal area.

Surgery for recurring anal vein thrombosis
In cases of severe or frequently recurring perianal vein thrombosis, a surgical procedure may also be indicated. In this procedure, the blood clot is usually completely removed through excision in a short outpatient procedure. This procedure is usually performed under local anesthesia and can accelerate the healing of the ulcer at the anus and reduce the risk of recurrent thrombosis. The wound is not stitched and remains open. Therefore, wound care after the operation plays an important role. Certain suppositories for the treatment of anal vein thrombosis are also suitable to support the healing process after colorectal surgeries, such as excision of an anal thrombosis.
Can home remedies help with recurring anal vein thrombosis?
Those affected can initially treat recurring anal vein thromboses themselves with decongestant measures such as sitz baths or suppositories. Although perianal vein thrombosis is painful, it is generally considered harmless. Usually, a conservative therapy approach with suppositories or ointments is chosen to promote healing of the anal thrombosis and to reduce swelling of the knot and the surrounding tissue in the anal area. Do not forget that home remedies and naturopathy are no substitute for medical examination, diagnosis, and treatment. Read more here about the general treatment of perianal vein thromboses or tips on the use and dosage of suppositories for treating anal thromboses. Learn about the multifaceted benefits of CANNEFF® SUP suppositories to support the healing process of ulcers on the anus.
Those who are exposed to physical exertion in their profession should take breaks regularly and lie down. People who engage in very strenuous sports such as weightlifting should avoid it during an acute anal vein thrombosis to best avoid pressure in the abdominal and anal area caused by lifting heavy loads. In general, strict bed rest is not necessary for an anal vein thrombosis. Moderate exercise is advisable, also to prevent a recurrence of perianal thrombosis. Avoid sitting for long periods; instead, take breaks more often and lie down for a few minutes. This relaxes the pelvic floor and anal area and relieves pressure on the thrombosed vein. Many affected people also find it pleasant to cool the swollen area on the anus accordingly.
What complications can occur with recurring anal vein thromboses?
Recurrent anal venous thromboses can cause various complications, especially if not treated in time. These complications range from chronic issues such as persistent pain and swelling in the anal area, to scarring, anal fissures, but also secondary infections like an anal abscess. Thus, recurring anal venous thromboses, i.e., perianal thromboses that keep coming back, can also increase the development of symptoms related to hemorrhoids. Even if the anal venous thrombosis does not go away, it is referred to as a chronic anal thrombosis. This is the case when the anal thrombosis, i.e., the blood clot in the anal venous plexus, does not resolve or dissolve on its own. In this case, the anal venous thrombosis can cause permanent discomfort at the anus. If there is suspicion of a perianal thrombosis, discuss the symptoms of an anal venous thrombosis with your doctor. Read more here about diagnosis and examinations of perianal venous thrombosis by a doctor.
Therefore, we provide a brief overview of possible complications when an anal vein thrombosis occurs repeatedly or when the anal vein thrombosis does not go away, which also increases the risk of certain proctological secondary diseases.
Chronic complaints in the anus
Frequent anal vein thromboses can lead to persistent pain, swelling, and a constant feeling of discomfort in the anal area. Read more about the symptoms of anal vein thromboses here.
Formation of Marisks
Excess skin in the anal area can form from healed anal thromboses but also after repeated perianal thromboses. Recurring anal thromboses impair the elasticity of the tissue in the anal region. Skin tags (marisks) are usually considered harmless but can, if larger marisks occur, make cleaning the anal area more difficult and thus lead to symptoms such as anal itching. Larger skin tags (marisks) may also require surgery for removal.
Anal fissures
Repeated anal thromboses can irritate the sensitive skin around the anus and also cause tears in the anal skin or anal mucosa. Anal fissures are considered very painful, can also cause anal burning, and if wound healing disorders occur, chronic anal fissures can develop. Read more here about anal fissures and how you can speed up healing of anal fissures.
Anal abscesses and anal fistulas
Due to irritation or open wounds after surgery, or if the anal thrombosis bursts uncontrollably, secondary infections can develop in the anal area. Such irritations, wounds, or injuries at the anus can lead to infections. This consequently results in anal abscesses or even anal fistulas.
Hemorrhoids
Repeated swelling of the perianal blood vessels can also increase the risk of developing hemorrhoids. Complaints around the hemorrhoids can lead to further issues such as anal itching, bleeding, and pain at the anus.
Chronic anal venous thrombosis
If the anal venous thrombosis does not go away, a chronic form of anal venous thrombosis can develop in some cases. In chronic anal venous thrombosis, the blood clot is not completely dissolved and can thus cause persistent discomfort in the anal region.
Thus, early and correct treatment of an anal venous thrombosis as well as the prevention of various risk factors are the basis to minimize the likelihood of such complications or proctological secondary diseases.
Can recurring anal thromboses promote hemorrhoidal disease?
Yes, recurring anal thromboses can promote hemorrhoidal disease, but anal vein thrombosis and hemorrhoids are two different proctological conditions. An anal thrombosis is a painful swelling caused by a blood clot in the veins at the outer anus, while hemorrhoids are basically the vascular cushions or blood vessels in the anal canal. Recurring anal thromboses can lead to chronic damage and weakening of the vascular structure in the anal region. This increases the risk of developing hemorrhoidal disease. Frequent pressure and irritation of the vessels can cause dilation and relaxation of the veins, which facilitates the development of hemorrhoidal disease. However, it is important to clarify the exact causes individually, as the development of hemorrhoidal disease can be influenced by a variety of factors such as genetic predisposition, chronic constipation, sedentary activities, and overweight. Enlarged hemorrhoidal cushions also promote a slowing of venous blood flow and can thus also favor the development of perianal thromboses. Therefore, especially in cases of recurring perianal thromboses, the presence of enlarged hemorrhoids as the cause of the thrombosis should always be ruled out by an experienced proctologist. Read more here about the diagnosis and examinations of an anal vein thrombosis by a doctor.
Does a recurring anal vein thrombosis increase the risk of skin tags as a secondary condition?
Yes, recurring anal vein thromboses can also increase the risk of developing Marisken. An anal vein thrombosis occurs when a blood clot forms in a vein in the anal area. Even after the thrombosis has healed, in some cases, excess skin can form on the anus, a so-called sentinel fold, which is also called a Mariske. These skin flaps are usually harmless depending on their size, but larger Marisken can make cleaning the anal area more difficult and thus lead to anal itching or irritation in the anal area.
With recurring thromboses, the risk increases that a skin tag (Mariske) will form after the healing of the anal thrombosis, as the affected anal area is repeatedly exposed to mechanical and inflammatory processes. The elasticity of the skin can decrease after several perianal vein thromboses, leading to the formation of Marisken. Although Marisken usually do not cause serious health problems, they can be aesthetically disturbing or cause hygiene issues in the anal area. In some cases, removal of the Marisken, that is, surgery, may be considered if the Marisken cause corresponding complaints.
How can I prevent recurring anal vein thrombosis?
To reduce the risk of recurring anal vein thrombosis, there are several effective preventive measures. Diet plays a central role in preventing recurrence. A fiber-rich diet, high in fruits, vegetables, and whole grains, helps keep stools soft and prevents constipation. Adequate fluid intake is also important as it supports digestion and regulates the gut.
Besides diet, regular exercise is a crucial factor. Physical activity promotes blood circulation and helps reduce the risk of perianal thrombosis.
Avoiding prolonged sitting can also help reduce strain on the veins in the anal area. During bowel movements, strong straining should be avoided to minimize pressure on the veins in the anal area. A toilet stool can help you adopt a natural, more squatting and thus gentle position that facilitates bowel movements and reduces straining and therefore pressure in the anal area.
In addition, how you handle stress also plays an important role. Stress can negatively affect the gut and promote both constipation and diarrhea, both factors that increase the risk of developing anal vein thrombosis. Stress management strategies such as yoga, meditation, or breathing exercises can help you lower your stress levels and thus reduce the risk of recurring anal thrombosis. Read more here about preventing perianal vein thrombosis.
How exactly does stress affect gut health and the course of recurring anal vein thrombosis?
Stress, bowel health, and mental condition play an important role in the course of even recurring anal vein thrombosis. Chronic stress negatively affects the entire organism, including the digestive system. Under persistent stress, the body releases increased amounts of hormones such as cortisol, which negatively influence bowel motility (bowel movement). This can lead to digestive problems such as constipation or diarrhea—both are risk factors for the development and thus cause of anal vein thrombosis. When constipation occurs, excessive straining during bowel movements often increases pressure on the perianal veins or can also lead to anal fissures, a painful tear of the mucous membrane in the anal canal or anal skin. Diarrhea, on the other hand, can irritate the anal area and also promote inflammation, which likewise increases the risk of perianal thrombosis and other proctological diseases.
Moreover, stress often negatively affects the overall lifestyle. Stress can lead to unhealthy eating habits, lack of exercise, or poor sleep quality. All these factors indirectly contribute to the development of anal vein thrombosis, as a low-fiber diet and a sedentary lifestyle slow down the bowel and hinder digestion. Mental health is also a crucial factor. People suffering from anxiety disorders or depression are more prone to unhealthy behaviors. These behaviors worsen bowel health and increase the risk of digestive problems and thus also of anal vein thrombosis. Additionally, the psychological burden of recurring anal vein thrombosis can intensify symptom perception and increase suffering, which significantly impairs the quality of life of those affected.
Good stress management and promoting mental health can therefore help reduce the risk of a recurrent anal vein thrombosis. Stress reduction methods such as yoga, meditation, or breathing exercises can positively influence bowel function by regulating digestion and preventing constipation. A conscious approach to one’s diet and incorporating regular exercise also contribute to improving gut health and reduce the risk of digestive problems that could lead to anal thrombosis.
Overall, there is a clear connection between mental and physical well-being, gut health, and thus the prevention of recurring anal vein thrombosis. A balanced lifestyle that strengthens physical and mental health can help to better control the condition in the long term.
