摘要

目的　应用多层螺旋CT血管造影（MSCTA）联合后处理容积重建（VR）技术显示右肺上叶静脉，对其解剖结构进行分类。方法　95例患者行肺动静脉造影，应用VR技术显示右肺上叶静脉，研究其分支类型及引流静脉归类概况。结果　（1）右肺上叶前静脉有多支，95例患者共268支，走形复杂，主要收集右肺上叶前段和尖段血液，有18例走形于右肺水平裂，收集右肺上叶前段和右肺中叶的血液；右肺中央静脉为1支，共95支，走形于右肺上叶前段和尖段支气管中间；右肺上叶后静脉较少出现，共14支，其中5支直接汇入左心房。（2）右肺上叶肺静脉分型中，“前+中央静脉”型最为常见，有81例（85.2 %），“前+中+后静脉”型14例（14.8%），单纯的“前静脉”型和“中央静脉”型本研究未发现。结论　MSCTA联合后处理VR技术可以真实直观地显示右肺上叶静脉的分支形式。

Abstract

Objective　To study the pulmonary veins of the right upper lobe with multi-slice spiral CT angiography (MSCTA) combined with the post-processing technology of volume rendering (VR). Methods　Totally 95 patients underwent multi-slice CT pulmonary venography. The right upper vein was displayed with VR technology, then the right upper pulmonary veins was classified and the segmental veins with the VR technology was studied.　Results　(1)There were a total of 268 venous branches with complex shape in the anterior superior lobes of the right lung, mainly draining the anterior segment of the right upper lobe and the tip of the lung in 95 cases; There were 18 branches in the right lung horizontal fissure, draining the right upper lobe and the right lung mid-lobe. The central vein of the right lung had one branch in 95 cases, which was shaped in the middle of the anterior segment of the right upper lobe and the middle of the apical segment of the right lung. The veins in the upper lobe of the right lung appeared scarce, with a total of 14 branches, and with 5 directly into the left atrium. (2)The pulmonary veins of the right upper lobe were mainly classified as “pre+central vein” type in 81 cases (85.2%), and as“pre+middle+posterior vein” type in 14 cases (14.8%), which were described in the previous literature. The lonely “anterior vein” and “central vein” types were not found in this study.　Conclusion　MSCTA combined with post-processing VR technology can truly visualize the branch form of the right upper lobe vein.
