To the Editor:
I read with interest the case report by Puchakalaya and Tremper (1). The practice in our hospital is similar to that described by the authors, as we also insert the spinal drainage catheter into the patient before surgery on thoracic and thoracoabdominal aortic aneurysms. I am concerned about advancing the catheter 17 cm into the intrathecal space. We only advance the catheter 5 cm into the intrathecal space. The authors postulated that the mechanism of spinal cord injury might have been a result of coiling of the catheter and subsequent uncoiling on removal resulting in spinal cord injury. Fortunately, there were no long-term neurological sequelae. However, advancing a shorter length of catheter into the intrathecal space might have reduced the risk.
