部分性肺静脉异位引流多层螺旋CT表现及其诊断价值

The manifestations and the value of multi-slice CT in the diagnosis of partial anomalous pulmonary venous connection

目的:探讨MSCT对部分性肺静脉异位引流(PSPVC)的诊断价值。方法:回顾性分析5例经手术或心导管造影确诊的PAPVC患者的MSCT及后处理重组影像资料。结果:MSCT血管成像对5例PAPVC均做出正确诊断,包括2例心上型,2例心内型,1例心下型;发生部位均为右侧肺静脉,其中右上肺静脉4支,右下肺静脉3支;4例患者存在肺动脉高压表现;1例合并右位降主动脉及胸椎畸形。5例患者均出现不同程度的右心房及右心室增大。结论:MSCT能够对PAPVC作出准确诊断,可作为该病的首选检查方法。

Objective:To study the multi-slice CT (MSCT) appearances and to evaluate the diagnostic value in patients with partial anomalous pulmonary venous connection (PAPVC). Methods:Five patients with PAPVC confirmed by surgery or cardiac catheterization were collected and their MSCT as well as post-processed imaging materials were analyzed retrospectively.Results:All patients were diagnosed by MSCT accurately including supracardiac type (n=2),intracardiac type (n=2) and infracardiac type (n=1).All of the anomalous pulmonary veins occured at right pulmonary vein (PV) with right superior PV (n=4) and right inferior PV (n=3).Pulmonary hypertension appeared in four cases and 1 case had co-exsiting right sided descending aorta and thoracic vertebra anomalies.Enlargement of right atrium and right ventricle with various degree could be assessed in all 5 cases. Conclusion:PAPVC could be accurately diagnosed by MSCT,which is the method of choice for the diagnosis of this disease entity.
