Knowledge of vascular anatomy and its possible variations is essential for performing embolization or revascularization procedures and complex surgery in the pelvis. The obturator artery (OA) is a branch of the anterior division of the internal iliac artery (IIA), and it has the highest frequency of variation among branches of the internal iliac artery. Possible anomalies of the origin of the obturator artery (OA) should be known when performing pelvic and groin surgery, where its control or ligation may be required. The purpose of this systematic review and meta-analysis, based on Sanudo's classification, is to analyze the origin of the obturator artery (OA) and its variants.
Thirteen articles published between 1952 and 2020 were included.
The obturator artery (OA) was present in almost all cases (99.8%): the pooled prevalence estimate for the origin from the IIA axis was 77.7% (95% CI 71.8-83.1%) vs. 22.3% (95% CI 16.9-28.2%) for the origin from EIA axis. In most cases, the obturator artery (OA) originated from the anterior division trunk of the internal iliac artery (IIA) (61.6%).
Performing preoperative radiological examination to determine the pelvic vascular pattern and having the awareness to evaluate possible changes in the obturator artery can reduce the risk of iatrogenic injury and complications.
了解血管解剖结构及其可能的变异对于在骨盆进行栓塞或血管重建手术以及复杂手术至关重要。闭孔动脉（OA）是髂内动脉（IIA）前干的分支，在髂内动脉各分支中变异频率最高。在进行骨盆和腹股沟手术时，可能需要控制或结扎闭孔动脉（OA），因此应了解其起源的可能异常情况。本系统评价和荟萃分析基于萨努多分类法，旨在分析闭孔动脉（OA）的起源及其变异情况。
纳入1952年至2020年间发表的13篇文章。
几乎所有病例（99.8%）均存在闭孔动脉（OA）：起源于髂内动脉轴的合并患病率估计为77.7%（95%CI 71.8 - 83.1%），而起源于髂外动脉轴的为22.3%（95%CI 16.9 - 28.2%）。在大多数情况下，闭孔动脉（OA）起源于髂内动脉（IIA）的前干（61.6%）。
进行术前影像学检查以确定骨盆血管模式，并意识到评估闭孔动脉可能的变化，可降低医源性损伤和并发症的风险。
