摘　　要：目的:探讨利用磁共振血管成像(MRA)原始数据集及三维重建软件构建在体女性骶前静脉丛三维模型的方法,观察骶前区静脉解剖。方法:2012年10月于南方医科大学南方医院获取10名青年健康未育女性磁共振检查原始数据集,利用Mimics 10.0软件重建骶前静脉丛三维模型,以及骨盆、盆腔动脉三维模型。结果:构建出骶前血管网,其中骶横干静脉、骶正中静脉、骶外侧静脉可清楚显示,将其与骨盆、盆腔动脉三维模型配准融合,骶前静脉丛与动脉走行关系、骶前区无血管区域一目了然。结论:利用MRA原始数据集能够重建女性骶前静脉丛,为研究骶前血管提供一种方法,且具有较好的临床实用性。Objective：To explore the method to construct the three-dimensional of the presacral venous plexus based on Magnetic Resonance Angiography（MRA）, observe the vascular anatomy of the presacral space. Methods：The original Dicom datasets were obtained from 10 young healthy nulliparous woman by MRA in Nanfang Hospital of Southern Medical University in October 2012. Then the pelvic venous vascular network,pelvis,pelvic artery vascular were reconstructed by inputting the datasets into Mimics 10.01 software. Results：The digital three-dimensional models of pelvic venous vascular network was built,which could clearly show middle sacral vein,transverse veins,and lateral sacral vein. Combined with the view of venous vascular network with pelvis and pelvic arterial vascular network,the anatomic structure and drainage region of pelvic veins are much more clearer. Conclusions：To construct the three-dimensional of the presacral venous plexus based on MRA is an effective method to investigate the relative safety area anatomy, which has better clinical utility.
