Acute subdural hematoma following lumbar cerebrospinal fluid drain for thoracoabdominal aortic aneurysm repair

Intracranial Subdural hematoma is a rare but potentially catastrophic complication after Cerebrospinal fluid drainage (CSFD) for thoracoabdominal aortic aneurysm repair. We report a patient with an acute left frontoparietal subdural hematoma following insertion of lumbar drain for prevention of spinal cord ischemia after thoracoabdominal aortic aneurysm repair. He presented with delayed neurological deficits which were completely reversed after surgery. The rationale for systematic use of lumbar drainage of Cerebrospinal fluid (CSF) in Thoracoabdominal Aortic Aneurysm (TAAA) repair is discussed.
