[Discrepancy between clinical and radiologic manifestations of an epidural hematoma after catheterization]

Abstract

Neuraxial techniques are considered safe if certain guidelines are followed, but they are not risk free. We report the case of an 81-year-old woman with an invasive bladder tumor who underwent radical cystectomy with a Bricker-type procedure. General anesthesia was used and epidural analgesia was also provided for surgical and postoperative pain management. Late in the postoperative recovery period a large epidural hematoma was diagnosed based on radiologic signs of spinal cord compression, in the absence of symptoms other than mild and progressive back pain that developed after extubation. The surgeon decided against emergency surgery to reduce compression. Symptoms resolved gradually, and a magnetic resonance image 45 days after discharge confirmed that the hematoma was smaller. In addition to the usual safety recommendations for epidural anesthesia with regard to drugs that alter hemostasis, it is important to bear in mind circumstances that have pharmacokinetic repercussions and that increase risk. Lower back pain can be a warning sign. Some cases may resolve spontaneously.
