Regional blood flow occlusion during extensive pelvic procedures for ovarian cancer: a randomized trial

The objective of this study was to determine the effects of intraoperative aortic occlusion on blood loss and operative time when used during en bloc resection of internal reproductive organs, pelvic peritoneum, and rectosigmoid colon [modified posterior exenteration (MPE)] for primary cytoreduction of ovarian cancer. Patients undergoing MPE, without palpable distal aortic plaque or calcification, were randomized to: (a) complete distal aortic occlusion (
