Arteriovenous malformation (AVM)
An AVM is an abnormal tangle of arteries and veins with a direct connection, bypassing the capillary network. This can lead to high-pressure blood flow through the malformation, potentially causing bleeding, seizures, or neurological deficits.
Although arteriovenous malformation (AVM) has been considered to be a congenital vascular malformation, morphological differences associated with age have been indicated in the literature.
Classification
Clinical Presentation
Although many AVMs are asymptomatic, they can cause intense pain or bleeding or lead to other serious medical problems.
Complications
They have a higher rate of bleeding than normal vessels. AVMs can occur anywhere in the body.
