Scope note: Formación anormal de vasos sanguíneos que derivan sangre arterial directamente a las venas sin pasar a través de los CAPILARES. Suelen ser tortuosos, dilatados y con gruesas paredes vasculares. Un tipo común es la fístula arteriovenosa congénita. La ausencia de flujo de sangre y oxígeno en los capilares puede llevar a daño tisular en las áreas afectadas.

Scope note: 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.
