摘　　要：目的探讨CT血管造影(CTA)在动脉性大出血介入栓塞治疗中应用的策略及临床效果。方法 120例动脉性大出血患者在介入栓塞治疗前行CTA检查,在介入手术中寻找所有的出血动脉,并逐一进行栓塞治疗。88例患者栓塞治疗2周后复查CTA检查。对CTA在动脉性大出血介入栓塞治疗中的应用效果进行回顾性总结评价。结果120例动脉性大出血的患者在介入栓塞治疗前行动脉CTA检查,共找到162支病变的出血动脉,介入手术中共找到178支出血动脉并成功栓塞治疗。术前CTA检查诊断的准确率为91.01%(162/178)。88例患者栓塞治疗后CTA检查显示所有已栓塞的出血动脉栓塞效果良好。结论介入栓塞治疗前CTA检查可以为栓塞治疗中寻找出血动脉提供准确的定位作用。栓塞治疗后行CTA检查有利于对栓塞疗效的准确判定。Objective To explore the strategy and clinical effect of CT angiography in embolotherapy of massive arterial haemorrhage. Methods 120 patients of massive arterial haemorrhage underwent angiography before embolotherapy. All bleeding arteries were found and blocked one by one in embolotherapy. CTA was conducted after two week of embolotherapy in 88 patients. The strategy and clinical effect of CTA in embolotherapy of massive arterial haemorrhage was analysed retrospectively. Results All 162 bleeding arteries were found in 120 patients underwent CTA before embolotherapy. 178 bleeding arteries were located and embolized successfully in embolotherapy. Diagnostic accuracy of CTA before embolotherapy was 91.01% （162/178）. CTA after embolotherapy confirmed the embolized bleeding arteries were blocked completely in 88 patients. Conclusion CTA before embolotherapy can provide the effect of location for finding the bleeding arteries in embolotherapy. CTA after embotherapy is conducive to determine the efficacy of embolization.
