Endovascular Embolisation of a Complex Arteriovenous Malformation
Abstract: Arteriovenous brain malformations are congenital diseases, considered anomalies in the development of the cerebral vessels. V can be localized in any brain region, their most frequent localization being in the basin of the middle cerebral arteries. They have different size starting from few millimeters to affecting the entire brain hemisphere. The supplying arteries may be one or several, and may be with a dilated lumen or just conform to the remaining normal cerebral arteries. The draining vein may also vary depending on their number, so they can be deep or cortical.1 From anatomic viewpoint they represent a complex net of afferent arteries and efferent (draining) veins, which are connected by a pathological capillary base the so called nidus. Clinically the brain AVMs are cause for mortality or long-lasting disablement of patients due to intracranial hemorrhage or epilepsy, for which they are the underlying reason.
