[A Case of Epidural Hematoma after Removal of Epidural Catheter in a Patient with Coagulation Disorder].

A 75-year-old man with abdominal aortic aneurysm underwent Y-graft replacement under combination of general anesthesia and epidural anesthesia. Although we inserted an epidural catheter at first attempt from T11-12, nurse cut the epidural catheter accidently. We re-inserted from the same place.
