Objective

To systematically assess available information about all variations of obturator vessels and to present the most surgically relevant types, their prevalence and calibre in order to provide a comprehensive overview for both anatomists and clinicians.

Materials and methods

A total of 2689 studies were found via searching the online databases. After applying exclusion criteria 44 studies were assessed. The cadaveric studies, CT angiographies, and clinical studies were included. Number of hemipelves, prevalence of each variation and calibre of identified vessels were studied. Each variation was classified as aberrant obturator artery/vein, aberrant accessory obturator artery/vein or anastomosis.

Results

In included studies the average incidence of the variant obturator artery was 26% with the aberrant obturator artery being the most frequent type (with the mean calibre 2.10 mm, SD = 0.35 mm), while the overall incidence of the variant obturator vein was 55%. Presented venous structures had the mean calibre of 2.98 mm (SD = 0.56 mm).

Conclusions

According to reviewed studies, variant obturator vessels are present in a great number of patients. Due to their possible calibre larger than 3 mm they represent a structure of high clinical importance. It is important to unify the terminology and to stress out the significance to all clinicians.

闭孔血管的解剖变异性：文献的系统回顾

客观的

系统评估有关闭孔血管所有变化的可用信息，并呈现与手术最相关的类型、其患病率和口径，以便为解剖学家和临床医生提供全面的概述。

材料和方法

通过搜索在线数据库，总共找到了 2689 项研究。应用排除标准后，对 44 项研究进行了评估。包括尸体研究、CT 血管造影和临床研究。研究了半脑的数量、每种变异的发生率以及已识别血管的口径。每种变异被分类为异常闭孔动脉/静脉、异常副闭孔动脉/静脉或吻合。

结果

在纳入的研究中，闭孔动脉变异的平均发生率为 26%，其中异常闭孔动脉是最常见的类型（平均口径 2.10 mm，SD = 0.35 mm），而闭孔静脉变异的总体发生率为 55% 。所呈现的静脉结构的平均口径为 2.98 毫米 (SD = 0.56 毫米)。

结论

根据回顾性研究，大量患者存在闭孔血管变异。由于它们的口径可能大于 3 毫米，因此它们代表了具有高度临床重要性的结构。统一术语并强调其对所有临床医生的重要性非常重要。
