Background.Background.Severe int raoperative bleeding can not always be controlled by standard surgical tech-niques. We recently reported a new te chnique to repair serious vascular injury using a free graft of omentum or rectus abdominus fascia as an overlaying autogenous tissue (OAT) patch in the experimental sheep model. We nowdescribe the successful clinical use of this patch in three patients. Case Reports. Radi al surgery was per-formed on three patients with pelvic malignancy with re-sulting uncontrollable bleeding fr om the internal iliac vein, pelvic side wall and paravaginal venous plexuses, respec- tively. Hemostasis was secured usin g an OAT patch made of abdominus rectus fascia in two cases and appendix epi-ploicae as an omental substitute in t he other. Disussion. The utility of the OAT patch is described in three different clinical situations. It is suggeste d that this technique may be more useful to gynecologic oncologists when stan-dard surgical techniques fail to con trol ble eding or there is limited access to the site of injury.
