作者们报告两例因行右下颌骨部分切除(恶性肿瘤)、颈外动脉结扎术和鼻咽部纤维血管瘤切除术(经硬腭径路),于术后发生颈内动脉栓塞而出现进行性偏瘫,经颈动脉造影证实分别于颈内、外动脉分歧部及分歧上部2厘米处有完全性栓塞,经保守疗法无效死亡。虽在战伤中能见到颈部穿通伤时可并发颈内动脉栓塞,但在头、颈部闭合性外伤时则不易发生。这两例均发生在头颈部区域内术后,可能与
The authors report two cases of progressive hemiplegia due to internal carotid artery embolization after partial resection of the right mandible (malignant tumor), external carotid artery ligation, and nasopharyngeal angiofibroma resection (transpedicular approach). Contrast-enhanced carotid angiography demonstrated complete embolization at the internal and external branches of the internal and external branches of the cervix and 2 cm above the bifurcation, and died after conservative treatment. Although internal carotid artery embolization can be seen when a neck piercing injury is seen in a war wound, it is not likely to happen when the head and neck are closed. Both of these cases occurred after surgery in the head and neck area, possibly with
