合并颅内外动脉异常交通支的颌面部血管畸形的诊治

目的分析颌面部血管畸形合并颅内外异常交通支的临床资料及特点，为避免脑异位栓塞提供参考。方法分析对有适应证的120例颌面部血管畸形行患侧颈内、外动脉和椎动脉造影及供瘤动脉栓塞治疗中14例合并颅内外动脉异常交通支患者的临床资料。结果14例中9例栓塞前，5例栓塞后发现颅内外存在异常交通支，占同期血管内栓塞治疗病例的11.7%(14/120)，其中枕-椎动脉交通11例，咽升-椎动脉交通1例，颌内-眼动脉交通2例。14例中蔓状血管瘤（动静脉畸形）9例，海绵状血管瘤（静脉畸形）4例，葡萄酒色斑并巨唇症1例。结论当颌面部血管畸形合并颅内外异常交通支时，在数字减影血管造影术（digital subtraction

Maxillofacial vascular malformation associated with abnormal communication between external carotid and cranial arteries

Objective To introduce the clinical characteristics of maxillofacial vascular malformation with abnormal communication between external carotid and cranial arteries. Methods One hundred and twenty patients with maxillofacial vascular malformations had been studied by arteriography of internal and external carotid, and vertebral arteries before embolization of tumor supplying artery. Cases found to have communications between extra and intra cranial arteries were analyzed. Results Fourteen patients (11.67%, 14/120 ) were found to have abnormal communications between external carotid and cranial arteries. Among them, 11 patients demonstrated communications between occipital and vertebral arteries, 1 patient showed ascending pharyngeal artery and vertebral artery communication, and 2 patients showed maxillary artery ophthalmic artery communication. Conclusion Embolization of tumor supplying artery is a safe and practical method for the treatment of maxillofacial vascular malformation when done under digital subtraction angiography and superselective catheterization to avoid the abnormal communicant branches.
