CT肺动脉造影对肺动脉栓塞的诊断价值

Diagnosis Value of CT Pulmonary Arteriography in Pulmonary Embolism

目的探讨CT肺动脉造影对肺动脉栓塞(PE)的诊断价值。方法20例PE患者均行CT肺动脉造影(CTPA)检查。结果Ⅰ型12例,其中4例位于左肺动脉,3例位于右肺动脉,5例左、右肺动脉及肺叶肺动脉皆有;Ⅱ型2例,其中右下叶肺动脉1例,左上叶肺动脉1例;Ⅲ型3例,其中右下叶肺动脉1例,左上叶肺动脉1例,2个以上肺叶肺动脉1例;Ⅳ型3例,均位于双下肺肺段、亚段肺动脉。左、右肺动脉、叶肺动脉、段肺动脉、亚段肺动脉栓塞率分别为77.78%、66.67%、60.00%、12.50%。结论CTPA对肺动脉栓塞有重要的诊断价值。

Objective To investigate diagnosis value of CT pulmonary arteriography （CTPA） in pulmonary embolism （PE）. Methods Twenty PE patients all had the examination of CTPA. Results Twelve cases showed type Ⅰ. Among them four located in left pulmonary artery; Three located in right pulmonary artery, and five located in left and right lobar pulmonary artery. There were two cases with type Ⅱ. Among them one located in right lower lobe pulmonary artery, one located in left superior pulmonary lobe artery. There were three cases with type Ⅲ. Among them one located in right lower lobe pulmonary artery, one located in left superior lobe pulmonary artery, and one located in more than two lobe pulmonary arteries; Three cases showed type Ⅳ,all them located in segment and inferior pulmonary artery of under double lung. Rate of PE in left and right pulmonary artery, lobe pulmonary artery, segment pulmonary artery and inferior pulmonary artery each was 77.78 %,66.67 %, 60.00 %, and 12.50%, respectively. Conclusion CTPA has important diagnosis value in PE.
