肺隔离症引发大咯血的介入治疗

目的探讨血管造影及栓塞术治疗肺隔离症引发大咯血的临床价值及其安全性。方法对12例肺隔离症引发大咯血患者,通过血管造影明确诊断。采用明胶海绵颗粒和真丝线段栓塞异常供血动脉网。结果对12例肺隔离症患者,通过血管造影,共发现异常供血动脉26支,均发自胸主动脉。表现为供血动脉主干明显增粗、扭曲,中远段血管呈毛线团状,远端相互吻合成丰富的血管网。11例患者病变区有数支血管共同组成。栓塞异常供血动脉后,咯血停止。随访6～18个月,无复发及并发症出现。结论血管造影及利用明胶海绵颗粒及真丝线段栓塞肺隔离症引发大咯血具有较高的临床应用价值和安全性。

Interventional therapy for massive haemoptysis due to pulmonary sequestration

Objective To evaluate the clinical value and safety of angiography and embolization in the treatment of pulmonary sequestration causing massive haemoptysis. Methods Though digital subtraction angiography(DSA), abnormal arteries were demonstrated in 12 cases with massive haemoptysis. All the abnormal arteries were embolized by gelatin sponge plus silk thread sterilized with high temperature and pressure. Results Among 12 cases of the pulmonary sequestration, 26 abnormal arteries were discovered, originating from thoracic aorta and presenting enlargement, twisting and irregular diameter with strands of middle and distal arterial segments associated with abundant vasculature network. There were several arteries supplying the lesion in 11 cases, and massive haemoptysis were stopped after embolization. Follow up for 6 to 18 months, no recurrence and no complication occurred. Conclusion Arterial angiography and embolization with gelatin sponge plus silk thread for treating pulmonary sequestration with massive hemoptysis possesses high clinical efficiency and safety.
