摘要
目的研究耳部动静脉畸形的动脉供血情况。方法 2006年4月至2011年6月,对14例耳部动静脉畸形患者行双侧颈外动脉、颈内动脉和椎动脉造影,记录供血动脉的起源及分支,观察耳部动静脉畸形供血动脉及其分布特点。结果 14例耳部动静脉畸形患者共有供血动脉37支,其中耳后动脉14支、颞浅动脉14支,枕动脉7支,对侧颞浅动脉1支、椎动脉1支,未见颈内动脉及其分支向耳部动静脉畸形供血。结论耳部动静脉畸形血供主要来自颈外动脉的耳后动脉、颞浅及枕动脉,对侧颞浅动脉、椎动脉供血少见,少见供血动脉需引起注意。
Objective To investigate the feeding arteries of auricular arteriovenous malformations （AVMs） with digital subtraction angiography. Methods During the period form April 2006 to June 2011, angiography of bilateral external carotid, internal carotid and vertebral arteries was carried out in 14 patients with auricular AVMs. The origins and the branches of the feeding arteries of auricular AVMs were determined and recorded. The origins and distribution features of AVM feeding arteries were analyzed. Results A total of 37 feeding arteries were observed in 14 patients. The feeding arteries were originated from posterior auricular artery （n = 14）, superficial temporal artery （n = 14）, occipital artery （n = 7）, contralateral superficial temporal artery （n = 1 ） or vertebral artery （n = 1 ）. Blood supply of auricular AVMs from internal carotid artery or from its branches was not seen. Conclusion The blood supply of auricular AVMs is mainly from the branches of ipsilateral external carotid artery, including posterior auricular artery, superficial temporal artery and occipital artery. Rarely, auricular AVMs can get their blood supply from contralateral superficial temporal artery or vertebral artery, and interventional radiologists should be aware of such unusual feeding arteries.
