嗅裂区鼻出血的特征

目的：探讨嗅裂区鼻出血的临床特征及治疗方法。方法：回顾性分析32例嗅裂区鼻出血患者的临床表现及治疗情况。结果：本组患者平均50岁，出血反复发作，病程长，多次鼻腔填塞；出血部位明确22例，不明确8例，蝶窦假性颈内动脉瘤2例；内镜下烧灼、钳夹及嗅裂区局部填塞成功止血21例，筛前动脉结扎6例，DSA治疗1例， 4例保守治疗自愈。结论：嗅裂区出血不易发现、治疗，用内镜及正确的检查方法发现出血点是关键。

Clinical features of oltactory cleft bleeding

Objective: To investigate the clinical features and management for olfactory cleft bleeding. Method: The clinical features and management for twenty-two patients with olfactory cleft bleeding were retrospectively analyzed. Results: Olfactory cleft bleeding was found in 22 cases, was uncertain in 8, and was induced by internal carotid artery pseudoaneurysm in 2. Under an endoscope, burnt and package were performed on 21 cases, ligation of the anterior ethmoid artery on 6, and DSA on 1. Four cases were healed under a conservative condition. Conclusion： Olfactory cleft bleeding is difficult to be found and treated. Nasal endoscopic surgery provides an effective and safe method for it.
