Hemorrhage from the presacral venous plexus is a potentially life-threatening complication of pelvic operations. The morbidity and mortality that stems from severe hemorrhage has led to the development of various hemostatic techniques. Although suture ligature, packing, and placement of tacks can be very effective, they can often be unsuccessful. When these conventional hemostatic techniques fail, alternative approaches are required. We describe the successful use of an expandable breast implant sizer and outline the practical, theoretical, and financial advantages of applying this technique when more conservative approaches have failed.
