目的 :观察肺动脉造影诊断肺动脉栓塞中的价值 ,及溶栓治疗后肺动脉的再通情况。方法 :穿刺右股静脉(Seldinger穿刺法 )置猪尾巴 (pigtail)于肺动脉主干近端分别多个体位造影 ,观察肺动脉内充盈、缺损及肺野有无血流灌注 ,肺动脉分支充盈和排空延迟情况。结果 :可见明显大动脉的缺损及肺动脉分支明显排空延迟。结论 :肺动脉造影是诊断肺栓塞最可靠的方法 Objective: To observe the value of pulmonary arteriography in the diagnosis of pulmonary embolism and pulmonary recanalization after thrombolysis. Methods: The pig tail was placed in the proximal part of the main pulmonary artery by Seldinger puncture. The filling and defect of the pulmonary artery and the perfusion in the lung field were observed. The pulmonary artery branch filling and emptying delay Happening. Results: Obvious obvious aortic defects and pulmonary artery was significantly delayed emptying. Conclusion: Pulmonary arteriography is the most reliable method to diagnose pulmonary embolism
