Vascular anomalies: A pictorial review of nomenclature, diagnosis and treatment

Figure 14 Particulate agents do not generally provide complete occlusion, and recanalization may occur. High flow arteriovenous malformation with nidus and venous aneurysm originating from branches of the left internal iliac artery (A). Following superselective catheterization of the feeding branch of the inferior gluteal artery there is demonstration of the nidus and venous aneurysm (arrow) (B). Following particulate embolization with PVA, there is occlusion of the nidus. Surgical clips are seen overlying internal iliac artery branches from previous unsuccessful attempts at surgical treatment (C).
