摘要
目的 分析颌面鼻咽部血循环特点 ,探讨安全有效的颈外动脉 (ECA)超选择性插管栓塞技术。方法 37例患者 ,疾病包括鼻咽纤维血管瘤、颌面血管畸形、鼻出血、上颌窦血管瘤、右眶内骨折出血、颈静脉球瘤、颈静脉球瘤并颈动脉体瘤、脑膜瘤、颅底硬脑膜动静脉瘘。均经ECA及分支数字减影血管造影 (DSA) ,有 2 5例共行 32支ECA及分支栓塞治疗。结果 均取得治愈或好转疗效。其中 1例右眼失明 ,1例左颊及耳廓坏死。结论 颌面鼻咽部血供丰富 ,侧支吻合多 ,ECA及分支DSA可明确病变血供 ,了解侧支及危险吻合情况。应尽量高超选择直接栓塞病灶 ,以提高疗效和减少并发症。正确选择导管及熟练操作是高超选择性插管成功的保证。不能超选择性插入分支者采用血流再分布原理进行栓塞。对活动性出血不能超选择性插管时可采取主干栓塞后局部降压而止血。
Objective To analyze the blood circulation character of supper catheterization and embolization in external carotid artery(ECA).Methods Thirty-seven cases (9 nasopharyngeal angiofibroma, 7 maxillojaw arteriovenous malformation, 5 nosebleeding, 1 maxillary hemangioma, 1 right orbital fracture with hemorrhage, 5 jugular glomus tumor, 2 jugular glomus tumor and carotid body tumor, 6 meningioma and 1 basal skull dural arteriovenous fistula) were passed through DSA of ECA and the branches, 32 branches of ECA were embolized in 25 cases.Results All cases obtained improvement or cure. One of them showed blindness of right eye and another one left in chap and auricle necrosis.Conclusion Catheterization through DSA embolization could be successfull achieved especially by supper selective approach for stopping bleeding in the rich blood supplied maxillojaw region with even better result by lowering local blood pressure.
