XXXX during a lumbar laminectomy.

@entity1317 @entity1 @entity1410
A lumbar laminectomy is a common and routine operation. Damage to abdominal vascular structures during surgery is a relatively infrequent complication; however, when it does occur, it is sudden and life-threatening. We herein report on 2 cases of @entity1317 which occurred during lumbar microdiscectomies. The first case was a 34-year-old @entity1 . A bloody surgical field was noted 45 min into the operation along with an increase in heart rate and a decrease in blood pressure. After fluid resuscitation and an ephedrine injection, his vital signs stabilized. The @entity1 was then sent to the surgical intensive care unit for observation. An emergent abdominal computer tomography scan revealed @entity1410 , and an urgent exploratory laparotomy was performed to check for bleeding and to remove the @entity1410 . The second case was a 61-year-old @entity1 with recurrent disc herniation. The operation was proceeding smoothly for 90 min, when a large amount of fresh blood suddenly gushed out. Her blood pressure immediately dropped to that of a state of shock. The @entity1 was turned back to a supine position, and an emergent laparotomy was done to repair the injured vessels. Both @entity1 had uneventful recoveries.
