摘要
目的探讨建立CT肺动脉（PA）及支气管动脉（BA）联合造影的方法及其对咯血患者的诊断价值。方法连续纳入北京朝阳医院2007年6月至2009年7月36例中等量及以上咯血住院患者，其中男21例，女5例，年龄27～83岁，平均（56±14）岁。使用16排螺旋CT，静脉注射对比剂后，首先完成CT肺动脉造影（CTPA），延迟时间12～16s，继之完成CT支气管动脉造影（CTBA），延迟时间26～28s，经图像重建后对PA及BA进行评价。结果36例患者CTPA检查发现7例PA异常（肺栓塞3例，PA畸形、原发性PA平滑肌肉瘤、PA边缘模糊及右下PA闭塞各1例）。36例患者CTBA检查共显示37支右侧BA，其中11支迂曲增粗、40支左侧BA及3支非支气管体循环动脉，其中来源于腹主动脉的1支迂曲增粗。异常血管与肺部疾病关系密切。结论利用16排螺旋CT技术，可进一步完成CTPA及CTBA检查，清楚显示异常的PA及BA，对咯血的诊断及治疗具有重要价值。
Objective To establish the method of muhi-slice spiral CT pulmonary angiography （CTPA） combined with bronchial angiography（CTBA） and to evaluate its value for diagnosis and treatment in hemoptysis. Methods After contrast material was administered intravenously, a 16-detector row helical CT scanner （Light Speed Ultra 16; GE Medical Systems） was used to complete CTPA first with a scan delay time of 12 - 16 s. Then CTBA was carried out, with a scan delay time of 26 - 28 s. The images were reformatted to evaluate the pulmonary artery and bronchial artery （BA）. Results In 36 cases of hemoptysis, CTPA showed 7 pulmonary arterial abnormalities （ 3 cases with pulmonary embolism, 4 cases with one of pulmonary artery abnormity, primary pulmonary artery leiomyosarcoma, loss of sharpness of pulmonary artery or occlusion of right-inferior lung artery）. In the 36 cases, CTBA showed 37 right BAs （11 tortuosity and thickening） ,40 left right BAs（ 10 tortuosity and thickening）and 3 non-bronchial systemic arteries（ 1 from abdominal aorta tortuosity and thickening）. Abnormal vessels had a close relation with pulmonary diseases. Conclusions With this method CTPA and CTBA can be completed in a single procedure and abnormal pulmonary arteries and bronchial arteries can be shown clearly. This procedure maybe of important value for the diagnosis and treatment of hemoptysis.
