Reappraisal of the Variations in the Origin of the Obturator Artery With Clinical and Developmental Perspectives: A Cadaveric Analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background The obturator artery (OA), typically originating from the anterior division of the internal iliac artery (ADIIA), shows significant variability in its origin. Such variations can present clinical challenges during pelvic surgeries, potentially causing unnoticed bleeding and complicating effective treatment. This study aims to thoroughly document the diverse anatomical variations of the OA and explore their implications for surgical practice. Materials and methods Forty-eight hemipelvis specimens from adult human cadavers were dissected. The origin of each OA was meticulously documented, photographed, and analyzed descriptively. Results In 38 specimens (79.2%), the OA originated from the IIA. It branched off at various levels from either the ADIIA or the posterior division of the IIA (PDIIA), either individually or in combination with other named branches. In nine cases (18.8%), the OA originated directly from the external iliac artery (EIA), either as a distinct branch or alongside the inferior epigastric artery (IEA). Additionally, one specimen (2%) exhibited a dual origin involving both the ADIIA and the IEA. Conclusion These findings highlight the frequent anatomical variations in the origin and pathway of the OA. Understanding these variations is crucial for accurately assessing pelvic anatomical relationships, which is essential for effective surgical planning and ensuring procedural safety. This knowledge is particularly important during vascular and surgical procedures, as it can impact the risk of bleeding and the effectiveness of treatment strategies.
