Dr. Sumathilatha Sakthi-Velavan, Charlotte Gabbard-OMS-II, and Jacob
Carrico-OMS-II have published new research in Surgical and Radiologic Anatomy, highlighting a little-known yet clinically significant blood vessel.
Their review article, “Sampson’s Artery: Anatomical, Surgical and Radiologic Implications,” examines Sampson’s artery, a small vessel that runs alongside the round ligament of the uterus. While often overlooked, the artery can enlarge during pregnancy or pelvic disease, increasing the risk of severe bleeding in obstetric, gynecologic, and general surgical procedures.
The study highlights several important findings:
- - ampson’s artery most commonly branches from the inferior epigastric or external iliac artery.
- - It contributes to collateral circulation between the uterine and ovarian arteries.
- - It may be an underrecognized source of persistent hemorrhage following uterine artery embolization, post-operative bleeding following hernia repair, and other pelvic disorders.
Importantly, the authors note that awareness of Sampson’s artery among surgeons and trainees remains limited, underscoring the need for stronger anatomical education and clinical recognition.
The research reinforces a key message: even the smallest anatomical structures can significantly impact patient outcomes.
