Does ligation of the hypogastric artery at the time of radical hysterectomy and lymphadenectomy decrease blood loss? Results of a prospective randomized trial.

A prospective, randomized study of patients undergoing radical hysterectomy for gynecologic malignancies was undertaken from 10/95 to 11/96 to determine if ligation of the hypogastric arteries at the time of radical hysterectomy decreases blood loss. Patients were randomized to either ligation of the hypogastric artery (Group 1) or no ligation (Group 2) prior to a standard Piver type III radical hysterectomy. Surgeries were performed by Board certified gynecologic oncologists with gynecologic oncology fellows and/or OB/GYN residents. Patients were analyzed for demographic characteristics and intraoperative and postoperative parameters. Statistical analysis was performed with independent samples t-test, Mann-Whitney rank sum test, Chi square and Fisher exact test. Twenty-one patients were randomized to group 1 and 22 to group 2. Groups were similar with respect to demographics and preoperative parameters except for age. There were no differences among the groups with respect to intraoperative and postoperative parameters. The mean estimated blood loss for group 1 was 600 ml and 550 ml for group 2 (P = NS). Hypogastric artery ligation (HAL) at the time of radical hysterectomy for gynecologic malignancy does not reduce blood loss.
