支气管动脉栓塞治疗咯血的临床疗效

目的 探讨支气管动脉栓塞术治疗咯血的临床疗效及其影响因素。方法 对14例急性或慢性反复咯血患者，先作选择性支气管动脉血管减影显像（DSA）检查，明确出血部位后，行超选择性插管，用明胶海绵栓塞。结果 均1次栓塞成功，咯血立即停止13例，咯血明显减少1例，即时止血率92．8％，有效率100％，近期复发率7．14％，均无并发症。结论 支气管动脉栓塞术治疗咯血的疗效满意；复发咯血与原病变及栓塞材料有关；推荐用微导管超选和用PVA栓塞。

Clinical Efficacy of Bronchial Arterial Embolization in the Treatment of Hemoptysis

Objective To investigate the efficacy and influential factors of bronchial arterial embolization in the treatment of hemoptysis. Methods Fourteen patients with acute or chronic repeated hemoptysis underwent selected DSA in the bronchial artery to identify bleeding part and then were performed by superselective catheterization following gelatin sponge embolization. Results All 14 cases were embolized successfully at a time, among whom 13 had immediate hemoptysis and 1 had a significant decrease in hemoptysis with a hemostasis rate of 92.8%, an effective rate of 100% and a short-term recurrence of 7.14% and all without complications. Conclusion Bronchial arterial embolization in the treatment of hemoptysis can have a satisfactory efficacy. The recurrent hemoptysis may be associated with primary affection and embolization material. Therefore, it is recommended that the superselective DSA be performed by utilizing microtubular and embolized with PVA.
