BACKGROUND
The obturator artery (OA) often presents multiple anatomical variations. These can be an atypical origin, variable anastomosis, or abnormal course within the pelvis.
METHODS
This study aimed to report a rare arterial variation in a Puerto Rican female cadaver that showed two abnormal obturator arteries with multiple pelvic branches. The OA emerged from the anterior branch of the internal iliac artery, which typically runs anteroinferior along the lateral wall of the pelvis to the upper part of the obturator foramen.
RESULTS
The atypical OA described in this report provided two variant branches. Abnormal obturator artery I (AOAI) emerged first and gave rise to three additional branches, while abnormal obturator artery II (AOAII) emerged second and gave rise to two other branches.
CONCLUSIONS
Identifying these accessory arteries is essential for surgical interventions, particularly within the field of gynecology and urogynecology. Knowledge regarding anatomical variations within this region must be assessed preoperatively to decrease the risk of iatrogenic injury.
背景
闭孔动脉（OA）常呈现多种解剖变异。这些变异可以是不典型的起源、可变的吻合或在盆腔内的异常走行。
方法
本研究旨在报告一名波多黎各女性尸体中一种罕见的动脉变异，该变异显示有两条异常的闭孔动脉，带有多个盆腔分支。闭孔动脉起源于髂内动脉前支，该分支通常沿盆腔侧壁向前下走行至闭孔上缘。
结果
本报告中描述的不典型闭孔动脉有两个变异分支。异常闭孔动脉I（AOAI）先出现并发出另外三个分支，而异常闭孔动脉II（AOAII）后出现并发出另外两个分支。
结论
识别这些副动脉对于手术干预至关重要，尤其是在妇科和泌尿妇科领域。术前必须评估该区域的解剖变异知识，以降低医源性损伤的风险。
