Artery of round ligament of uterus

The artery of the round ligament of the uterus, also known as Sampson's artery,[2][3] is a branch of the inferior epigastric artery.[4] It runs under, and supplies, the round ligament of the uterus.[5] It constitutes an anastomosis of the uterine artery and ovarian artery.[6] It was originally named after John A. Sampson (1873–1946), an American gynecologist who studied endometriosis.[7]

Clinical significance

It is considered an insignificant artery that is dissected during hysterectomies. It can be the source of hemoperitoneum,[8] but only rarely does it pose a hemodynamic risk to the patient if severed and it is easily cauterized or sutured to prevent bleeding.
