AVM

AVM or Arteriovenous malformation is a vascular anomaly that is characterized by a complex, tangled web of abnormal arteries and veins. It is a rare condition that affects less than 1% of the population.

Etymology

The term "arteriovenous malformation" is derived from the Latin words "arteria" (artery), "vena" (vein), and "malformatio" (misshaping).

Description

An arteriovenous malformation (AVM) is a specific type of vascular malformation that is characterized by an abnormal connection between arteries and veins, bypassing the capillary system. This vascular anomaly is widely recognized because of its potential for serious hemorrhage. AVMs can occur anywhere in the body, but are most commonly found in the brain and spine.

Symptoms

The symptoms of an AVM can vary greatly, depending on the location of the malformation. They may include headaches, seizures, and various neurological symptoms such as dizziness, difficulty speaking, or weakness on one side of the body. In some cases, an AVM can cause serious neurological deficits or life-threatening bleeding.

Diagnosis

The diagnosis of an AVM typically involves a combination of imaging studies, including computed tomography (CT), magnetic resonance imaging (MRI), and angiography. These tests can help to determine the size and location of the AVM, as well as the blood flow through the malformation.

Treatment

The treatment of an AVM can be complex and may involve a combination of surgery, radiosurgery, and endovascular embolization. The goal of treatment is to prevent bleeding from the AVM, while minimizing any potential neurological damage.
