A tangle of abnormally connecting arteries and veins, usually congenital.
An abnormal communication between or malformation between an artery and a vein that may occur congenitally or as of a result of an injury or infection.
A congenital anomaly that consists of abnormal arteries and veins without the presence of a capillary bed. May lead to bleeding in the brain.
Collection of blood vessels with one or several abnormal communications between arteries and veins which may cause hemorrhage or seizures.
abnormal, tangled collections of dilated blood vessels that result from congenitally malformed vascular structures in which the arterial blood flows directly into veins without passing through the capillaries
Abnormal communication between an artery and vein producing dilated vessels
A congenital disorder characterized by a complex tangled web of arteries and veins.
a congenital disorder in which there is an abnormal connection between arteries and veins without an intervening capillary bed.
A tangle of blood vessels in the brain.
An abnormal tangle of arteries and veins in which the arteries feed directly into the veins without a normal intervening capillary bed.
malformation of arteries and veins or the junction of the two.
Abnormal group of dilated blood vessels, most often occurring in the brain.
Arteriovenous malformation or AVM is a congenital disorder of the veins and arteries that make up the vascular system. The genetic transmission patterns of AVM (if any) are unknown, and AVM is not generally thought to be an inherited disorder--unless in the context of a specific hereditary syndrome.
