Sampson’s Artery

Other Known Aliases artery of the round ligament of the uterus

Definitionbranch of the inferior epigastric artery that runs under and supplies the round ligament of the uterus

Clinical Significance this artery constitutes an anastomosis of the uterine and ovarian artery and is generally considered an physiologically insignificant artery dissected during hysterectomies. However, if accidentally severed or damaged, can lead to hemoperitoneum and need for re-operation.

HistoryNamed after John Albertson Sampson (1873-1946), an American gynecologist who received his medical doctorate from Johns Hopkins University in 1899. He would spend the majority of his career at the Albany Hospital in New York and was a pioneer in the research of endometriosis, first introducing and coining the term for this condition in 1921. He would also be the first to describe the implantation areas of endometriosis as “chocolate cysts”. It was during his time at Johns Hopkins that he took a keen interest in oncology and extensively studied the lymphatic drainage and vascular supply of the pelvis, where he was later credited with his eponymous artery of the round ligament of the uterus.
