External carotid arteriovenous fistulas (AVFs) are rare and most hospitals have limited experience with their management. This study was designed to evaluate the effectiveness and safety of endovascular embolization of AVFs of the external carotid artery under angiographic control.
A series of 13 patients with AVFs involving the branches of the external carotid artery, all treated with endovascular embolization, were reviewed. There were 10 males and three females ranging in age from nine to 46 years, with a mean of 27 years. The most frequent presenting symptoms were pulsatile tinnitus, followed by bruit and/or thrill, ocular problems, headache and a pulsatile mass in the neck. The middle meningeal artery was most often involved, followed by the internal maxillary artery and the occipital artery. The AVFs were caused by trauma in 10 patients and occurred spontaneously in three. N-butyl-2-cyanoacrylate was used to embolize the fistula in 11 patients and a detachable balloon was used in two.
All the patients were cured and no significant complications were observed. No recurrence was noted after a clinical follow-up of three months to seven years (mean, 37 months).
Endovascular embolization proved to be a safe and effective procedure. It should be the treatment of choice for repair of external carotid AVFs.
颈外动静脉瘘（AVF）较为罕见，大多数医院在其治疗方面经验有限。本研究旨在评估在血管造影控制下对颈外动脉动静脉瘘进行血管内栓塞治疗的有效性和安全性。
回顾了一系列13例累及颈外动脉分支的动静脉瘘患者，均接受了血管内栓塞治疗。其中男性10例，女性3例，年龄9至46岁，平均27岁。最常见的症状是搏动性耳鸣，其次是血管杂音和/或震颤、眼部问题、头痛以及颈部搏动性肿块。脑膜中动脉受累最为常见，其次是上颌内动脉和枕动脉。10例患者的动静脉瘘由外伤引起，3例为自发性。11例患者使用N-丁基-2-氰基丙烯酸酯栓塞瘘管，2例使用可脱性球囊。
所有患者均治愈，未观察到明显并发症。临床随访3个月至7年（平均37个月）未发现复发。
血管内栓塞被证明是一种安全有效的治疗方法。它应成为颈外动静脉瘘修复的首选治疗方法。
