Arteriovenous fistulas of the external carotid artery are uncommon. They are usually of traumatic origin but in rare cases may be congenital. When located in regions with difficult access, they constitute a difficult surgical problem because of intra-operative bleeding and significant morbidity. With the advent of transcatheter embolization and new embolic agents, embolization has become the treatment of choice, with a cure rate of over 95%, low morbidity and brief hospitalization. Occlusion of the fistula itself, rather than occlusion of feeding pedicles, is achieved by super-selective catheterization and the use of a suitable permanent embolic agent, depending on location of the fistula and its flow characteristics. A girl aged 2 10/12 with a large, high-flow, arteriovenous fistula of the internal maxillary artery is presented. Complete occlusion of the fistula itself, with full cure, was achieved by super-selective transcatheter embolization using Gianturco coils. There has been no recurrence after more than 7 months of follow-up.
颈外动脉动静脉瘘并不常见。它们通常源于外伤，但在罕见情况下可能是先天性的。当位于难以接近的区域时，由于术中出血和显著的发病率，它们构成了一个棘手的外科问题。随着经导管栓塞术和新型栓塞剂的出现，栓塞术已成为首选治疗方法，治愈率超过95%，发病率低且住院时间短。通过超选择性插管并根据瘘管的位置及其血流特征使用合适的永久性栓塞剂，可实现瘘管本身的闭塞，而非供血蒂的闭塞。本文介绍了一名2岁10/12个月大的女孩，患有上颌内动脉大型、高流量动静脉瘘。通过使用Gianturco弹簧圈进行超选择性经导管栓塞，实现了瘘管本身的完全闭塞并完全治愈。随访7个多月后未出现复发。
