忌行供血动脉阻塞治疗颅面部动静脉畸形

Surgical ligation and occlusion of the feeding artery should not be used in management of arteriovenous malformations(AVMs)of the craniofacial regions

颅面部动静脉畸形虽然临床少见,但处理十分棘手。本文论述了颅面部动静脉畸形的临床表现、血管构筑、自然发展病程以及正确的治疗策略,从理论上探讨了单纯供血动脉栓塞或结扎不仅不能治疗动静脉畸形,还会加速病变的发展,为进一步血管内超选择治疗带来困难。为了取得良好的治疗效果,严禁行颈外动脉或供血动脉的结扎或堵塞治疗颅面部动静脉畸形。

Arteriovenous malformations （AVMs） are congenital vascular anomalies, which seldom occur in the craniofacial regions. The rarity of these lesions compounds their extreme management difficulty. The clinical manifestation, vascular architecture, natural progress history and therapeutic strategy on AVMs in the craniofacial regions were reviewed in this paper. It is concluded that surgical ligation or occlusion of feeding arteries proves totally futile as the phenomenon of neovascular recruitment reconstituted arterial inflow to the AVM nidus. The procedure should be prohibited to do because of the ineffectiveness and hindering further endovascular treatment.
