Protruding vein with bloody deposits in perianal thrombosis

Small perianal thrombosis that does not require treatment

In the perianal (complete: Perianalvenenthrombose , also briefly Analthrombose ) is a painful swelling in the region of the anus , which is caused by a blood clot in the superficial veins. It is often mistaken for a hemorrhoid by laypeople and is therefore also referred to as a false hemorrhoid .

root cause

According to recent prospective studies , extensive wet cleaning is a risk factor in addition to intensive physical exercise. These studies are the subject of controversy. In the no longer updated patient information for anal thrombosis of the German Society for Coloproctology , AMWF member , a. the following: "Frequently [...] acute after sitting on cold surfaces, [...] or for women during their period." "Pregnancy, childbirth, pressure increases in the abdomen when coughing, lifting or pressing, but also possibly certain foods (spices, alcohol ) can cause ". "Sometimes diarrhea triggers the development [...]." There it is also assumed that "the presence of large hemorrhoids favors the formation of anal thromboses". Sitting for long periods, regardless of the temperature of the seat, can also have a beneficial effect.

Symptoms

If a perianal thrombosis occurs, one or more bluish-red painful lumps form on the anus margin within a short time. A knot can contain several thrombi and reach the size of a cherry, in rare cases even the size of a plum.

therapy

The thrombosis can resolve itself after a few days or weeks. In acute cases, especially in severe pain, the perianal thrombosis is opened with an incision under local anesthesia and the thrombi are pushed out. Thereafter, healing usually occurs quickly and without consequences. Skin tags can occasionally develop later as a complication . Proctologists , surgeons, dermatologists, and some general practitioners can perform this procedure .

Oral pain relievers such as non-steroidal anti-inflammatory drugs ( NSAIDs ) such as diclofenac or ibuprofen , special ointments or suppositories are suitable as relieving measures . The latter should be free of Bufexamac because the approval was revoked by the BfArM with immediate effect on May 5, 2010 due to the triggering of contact eczema . Until now, it has been found in many hemorrhoid treatment products.
