摘　　要：目的:探讨鼻咽癌放疗后鼻咽部出血的原因。方法:回顾性分析70例因鼻咽癌放疗后鼻咽出血住院患者的出血原因。结果:70例患者中,由鼻咽癌复发引起鼻咽出血24例(34.3%),其中7例因大出血死亡;10例(14.3%)由假性动脉瘤引起,其中3例鼻咽大出血死亡;36例(51.4%)为鼻咽放疗后痂皮及肉芽出血,1例因大出血窒息死亡。结论:鼻咽癌放疗后鼻咽部出血是死亡率高的放疗并发症,其中以鼻咽癌复发及假性动脉瘤危险性最高,鼻咽癌放疗后痂皮及肉芽要积极处理。Objective：To investigate the cause of epitasis in patients irradiated for nasopharyngeal carcinoma.Method：Seventy nasopharyngeal carcinoma cases with epitasis after radiotherapy were retrospectively analyzed.Result：The causes of epitasis were local nasopharyngeal carcinoma recurrent 34.3%（24/70）,pseudoaneurysm 14.3%（10/70） and nasopharyngeal crust 51.4%（36/70）.Seven cases with local recurrent,3 cases with pseudoaneurysm and 1 cases with nasopharyngeal crust and osteoradionecrosis died of intractable epitasis.Conclusion：Epitasis in patients irradiated for nasopharyngeal carcinoma is dangerous complication, especially in cases with local recurrent and pseudoaneurysm. Nasopharyngeal crust must be treated actively.
