Research progress on the treatment of cerebral arteriovenous malformations by intravenous approach

Abstract

Intracranial arteriovenous malformations (AVMs) are congenital anomalies of the blood vessels. Three traditional methods of AVMs therapy have evolved to treat AVMs: microsurgery, stereotactic radiosurgery and transarterial embolization. The principle of treatment involves eliminating the nidus, which is the source of hemorrhage, without compromising normal arterial and drainage venous of the brain. More recently, The transvenous approach in treating AVMs was popularized by successful treatment models for dural arteriovenous fistulas and peripheral vascular malformations. Although this novel technique has its challenges and perils, successful treatment of cerebral arteriovenous malformations has been reported in several centers. In this artical, we reviewed the literature of AVMs treated by transvenous endovascular approaches, and summarized the progress of this method in the treatment of AVMs. Key words: Intracranial arteriovenous malformations; Transvenous approach; Intracranial hemorrhages; Drainage venous
