数字减影血管造影在严重鼻衄中的应用

DSA for the Treatment of Uncontrollable Epistaxis

本文对我院1994年来，采用DSA血管栓塞治疗的13例严重鼻衄进行了分析。其中11例栓塞颌内动脉后止血；1例去除前、后鼻孔填塞物仍出血，再次栓塞面动脉后止血；仅1例插管失败。栓塞止血有效率为92．3％。无严重并发症发生。DSA具有实时显像、轨迹减影透视等功能。在严重鼻衄治疗中，有简单、有效、安全等优点。文章讨论了DSA的操作要点、并发症预防措施。认为DSA血管栓塞可作为治疗严重鼻衄常现方法。

Thirteen patients with uncontrollable epistaxis were treated with digital subtraction angiograph (DSA) embolization since 1994. In 11 patients, the epistaxis was controlled after embolization of the intemal maxillary artery. In 1 patient, the nasal packing was removed and the epistaxis continued; the epistaxis was controlled after supplement embolization of the facial artery. Only 1 case was failure. The success rate was 92. 3% No severe complication occurred. DSA has instant subtraction, real-time subtraction, and road mapping. It is simple, efficient, and safe In this paper, the techniques and the methods for prevention of complications of emboliztion were also discussed. It is considered DSA embolization may be routine treatment for uncontrollable epistaxis.
