Preoperative and postoperative complications of cerebrospinal fluid drainage in descending thoracic and thoraco-abdominal aortic aneurysm surgery: a single-center retrospective study.

Bloody cerebrospinal fluid and meningitis, which are severe complications associated with spinal puncture, occurred within 1 day after spinal puncture. The incidence rates of moderate/mild complications were high in both the preoperative and postoperative periods. These results showed that CSFD catheter insertion and management should be performed carefully with consideration given to the risks and benefits of CSFD.
