摘要篇首： Massive presacral venous hemorrhage is a non-pulsatile hemorrhage due to the rupture of either the presacral venous plexus or the sacral vertebral basivertebral vein. It is a serious complication of surgery for pelvic tumors, like middle or low segment rectal cancers, advanced ovarian cancers and presacral tumors.Massive presacral venous hemorrhage is dangerous and difficult to manage. Traditional methods for controlling this condition include packing with laparotomy pads, the use of sterile thumbtacks,1 ligation of the internal iliac vessel,2 and selective arterial embolization.3 These methods are generally ineffective. Recently, several other methods for controlling presacral bleeding have been reported, such as occlusion of the wound with rectus muscle fragment welding,4 oppression with sterile normal saline bags,5 balloon tamponade,6 and the use of endoscopic staples.7 However, these measures fail to arrest the bleeding in some patients, resulting in massive hemorrhage and even death.
