摘要/Abstract

摘要： 目的　应用多层螺旋CT描述肺静脉的解剖变异并分型，为房颤射频消融术和心胸外科手术提供解剖依据。方法　回顾性分析250例应用MSCT行冠状动脉CTA检查的患者，通过多平面重建（MPR）、最大密度成像（MIP）和容积重建（VR）观察肺静脉解剖结构，对其分型并统计出现频率。结果　共同静脉出现率38.8%，副肺静脉出现率14.8%，均无性别差异。左心房-肺静脉连接方式可分4型：标准型最常见，有130例（52%）；共干型83例（33.2%），是最常见的变异类型；副静脉型23例（9.2%）；混合型14例（5.6%），最少见。两侧肺静脉引流模式的变异率为54%，右侧26.8%，左侧42%，均无性别差异。结论　肺静脉具有较大变异性，MSCT可详细显示肺静脉，是研究其解剖结构的有效手段。

Abstract: Objective　To describe and classify the anatomic variations of pulmonary veins by multi-slice spiral CT (MSCT), so as to provide anatomic basis for radio-frequency ablation of atrial fibrillation and cardio-thoracic surgery.　Methods　Two hundred and fifty patients underwent coronary CT angiography with MSCT were respectively analyzed. The anatomical structure of pulmonary veins was observed by post-processing techniques such as multi-plane reconstruction (MPR), maximum density imaging (MIP) and volume reconstruction (VR). The frequency of each type was classified and counted.　Results　The incidence of common vein and accessory pulmonary veins was 38.8% and 15.2%, respectively, with no gender difference. The left atrium and pulmonary vein connection could be divided into 4 types: 130 cases in standard type (52%), 83 cases in common vein type, which was the most common variation type(33.2%), 23 cases in additional vein type ( 9.2%), and 14 cases in mixed type ( 5.6%). The variation rate of bilateral pulmonary vein drainage patterns was 54%, 26.8% on right side, 42% on left side, with no gender difference.　Conclusions　Pulmonary veins has great variability. MSCT can display pulmonary vein in detail, which is an effective tool to study its anatomical structure.
