K64.5: Perianal venous thrombosis

You have blood clots in a blood vessel of your anus.

The anus is located at the end of the intestines and is ring-shaped. A sphincter muscle in the last segment of the intestines ensures that we only intentionally excrete feces through the anus.

If the blood does not flow off properly, blood clots can form. The likelihood of blood clots in the last intestinal segment is increased during a bowel movement. Bluish lumps often develop as a result of blood clots on the anus. The bluish lumps can then be seen on the anus.

Fluid often accumulates in the skin around these lumps. The lumps can also rupture. This can result in bleeding. You may often have severe pain in your anus as a result of the lumps, especially during a bowel movement.

  • V: Tentative diagnosis
  • Z: Condition after
  • A: Excluded diagnosis
  • L: Left
