本文报告3例由于血管异常所致后鼻孔顽固性出血病例。第一例患者因右筛窦肿物行手术切除后致后鼻出血。经结扎右筛前动脉和栓塞右颌内动脉及面动脉均不能止住,颈外动脉造影发现右面横动脉发出额外支至后鼻孔,栓塞该动脉及再栓塞右颌内动脉后鼻出血停止。第二例患者30年前因大脑动脉瘤行左侧颈内动脉结扎。此次后鼻出血虽经左颈外动脉结扎仍无效。血管造影显示由左椎动脉经右枕动脉重建颌内动脉血液循环。行左筛前动脉和颌内动脉远端结扎术治愈。第三例后鼻孔出血曾行右倾内动脉和筛前动脉结扎无效。动脉造影发现
This article reports 3 cases due to vascular abnormalities caused by intractable hemorrhage after the nostril. The first patient had a post-operative nosebleed due to surgical excision of the right ethmoid sinus. After the right anterior ligation of the artery and embolization of the right internal mammary artery and facial artery can not stop the carotid artery angiography found that the right transverse artery extra branch to the posterior nostril, embolization of the artery and re-embolization of the right internal mammary artery bleeding stopped. The second patient had an occlusion of the left internal carotid artery 30 years ago due to cerebral aneurysms. Although the post-nasal hemorrhage left ligation of the external carotid artery is still ineffective. Angiography showed reconstruction of the maxillary artery blood circulation from the left vertebral artery via the right occipital artery. Left anterior ethmoid artery and distal ligation of the internal carotid artery were cured. The third case after nostril hemorrhage had right internalization of the artery and anterior ethmoid ligation ineffective. Arterography found
