Bloody Cerebrospinal Fluid Drainage.

Bloody Cerebrospinal Fluid Drainage.:

The present images were obtained 48 h after thoracic endovascular aortic repair. The T2-weighted sagittal magnetic resonance image of the spine demonstrates a ventral subdural and subarachnoid hemorrhage (white arrows) extending from T12–L1 to the termination of the thecal sac at S2 (panel A). The axial image at L1 shows (white arrows) severe ventral compression of the conus medullaris (panel B). Lower extremity paresthesias followed by leg weakness were noted immediately after intended removal of a spinal drain prompting emergent magnetic resonance imaging necessitating surgical evacuation. Notably, 36 h before the first complaint of neurologic symptoms, bloody cerebrospinal fluid (CSF) was noticed in the spinal drain. The patient had normal coagulation status throughout the event.

Bloody CSF is considered benign if it ensues intraoperatively because the likely reason is...
