摘要

目的:应用计算机断层血管造影(CTA)三维重建技术研究女性髂静脉病变。方法:回顾性分析2009年12月至2018年12月1623例接受腹部和盆腔CTA扫描的妇科疾病患者。利用Mimics 19.0软件构建精确的髂静脉数字三维模型,研究其形态及变化。髂总静脉(CIV)、髂外静脉(EIV)和髂内静脉(IIV)的变异为I型,静脉数量异常;II型,通信分支异常;或III型,其他变种。结果:髂静脉和CIV的总变异率分别为51.57%(837/1623)和20.33%(330/1623)。CIV变异类型以II型为主。I型CIV变异以无CIV为主(98.15%),多发生在右侧(64.81%,35/54)。II型CIV变异最为常见,左侧CIV与右侧CIV之间的交流分支异常(81.78%,211/258)。EIV和IIV的总体变异率分别为36.66%(595/1623)和49.60%(805/1623),以右侧为主。变异类型以i型为主,其中以IIV分为两支并与同侧EIV汇合最为常见(22.98%,373/1623)。结论:在这项研究中,大约一半的患者有髂静脉变异。术前识别髂静脉变异可减少骨盆手术中的血管损伤。

Three-Dimensional in Vivo Anatomical Study of Female Iliac Vein Variations.

Objective: To investigate female iliac vein variations by using the computed tomography angiography (CTA) three-dimensional (3 D) reconstruction technique.

Methods: We retrospectively studied 1623 patients undergoing abdominal and pelvic CTA scanning for gynecological diseases from December 2009 to December 2018. Accurate digital 3 D models of the iliac vein were constructed using Mimics 19.0 software and used to study the morphology and variations. Variations in the common iliac vein (CIV), external iliac vein (EIV) and internal iliac vein (IIV) were classified as type I, abnormal number of veins; type II, abnormal communicating branches; or type III, other variations.

Results: The overall variation rates of the iliac vein and CIV were 51.57% (837/1623) and 20.33% (330/1623), respectively. The main type of CIV variation was type II. The main type I CIV variation was the absence of the CIV (98.15%), which mostly occurred on the right side (64.81%, 35/54). Type II CIV variation was the most common, with abnormal communicating branches between the left CIV and right IIV (81.78%, 211/258). The overall variation rates of the EIV and IIV were 36.66% (595/1623) and 49.60% (805/1623), respectively, mainly on the right side. The main type of variation was type I. Among them, the division of the IIV into two branches plus convergence with the ipsilateral EIV was the most common (22.98%, 373/1623).

Conclusion: In this study, approximately half of the patients had iliac vein variations. The preoperative identification of iliac vein variation may reduce vascular injury in pelvic surgery.
