AbstractAcute paraplegia caused by an epidural hematoma developed in a patient following the removal of an epidural catheter. This catheter had been used for 3 days for postoperative pain relief with no apparent complications. Heparin (10,000 units/day) had been infused for thrombosis prophylaxis and was associated with a normal activated partial thromboplastin time (aPTT) for the first two postoperative days. However, test results from blood drawn prior to catheter removal revealed, in retrospect, an unexpected prolongation of the aPTT (75 s) and PT (56%, Quick's method). An epidural hematoma extending from T12 to L4 was evacuated during emergency laminectomy and neurologic deficits resolved completely over the next days. Thus, the removal of an epidural catheter has the potential for inducing formation of an epidural hematoma. Accordingly, it may be safest to leave epidural catheters in place if test results demonstrate a bleeding diathesis or if a potential for bleeding is suspected on clinical grounds.
