Medical Subject Headings A0026492 AT73482559 Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.
MSHNOR A20198750 AT221475342 Unormal dannelse av av blodkar som shunter arterielt blod direkte over i vener uten å passere gjennom kapillærer. De er vanligvis krokete, utvidede og med tykke karvegger. En vanlig type er medfødt arteriovenøs fistel. Mangel på blodflyt og oksygen i kapillærer kan føre til vevsskade i affiserte områder.

Arteriovenous malformations (AVMs) are defects in your vascular system. The vascular system includes arteries, veins, and capillaries. Arteries carry blood away from the heart to other organs; veins carry blood back to the heart. Capillaries connect the arteries and veins. An AVM is a snarled tangle of arteries and veins. They are connected to each other, with no capillaries. That interferes with the blood circulation in an organ.

AVMs can happen anywhere, but they are more common in the brain or spinal cord. Most people with brain or spinal cord AVMs have few, if any, major symptoms. Sometimes they can cause seizures or headaches.

AVMs are rare. The cause is not known, but they seem to develop during pregnancy or soon after birth. Doctors use imaging tests to detect them.

Medicines can help with the symptoms from AVMs. The greatest danger is hemorrhage. Treatment for AVMs can include surgery or focused radiation therapy. Because surgery can be risky, you and your doctor need to make a decision carefully.
