Arteriovenous malformations (AVM) are abnormal connections between the arteries and veins. It is generally assumed to be congenital and is a vascular anomaly. Although this disease is mostly found in the central nervous system, it can occur anywhere in the body. The AVMs are not thought to result from a genetic disorder.
The symptomatic ones usually cause pain and swelling or, if they are on the body, skin discoloration. There is a possibility of causing bleeding. In the treatment, the ball part of the lesion called the nidus is closed with the endovascular (angioembolization) fluid blocking agents. Sometimes two sessions can be required. If the lesion is not very large, the patient can be discharged on the same day. There can be tingling for a few days after treatment. This treatment often offers a permanent solution.
