Résumé
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.

BACKGROUND
BACKGROUND
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.

RESULTS
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%).

CONCLUSIONS
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.
