Key result
Prophylactic cerebrospinal fluid drainage combined with standardized physiologic protocols reduced permanent spinal cord ischemia rates to approximately 2.1% compared to 4.9% with selective or no drainage after thoracic or thoracoabdominal aortic aneurysm repair.
Why the study?
Spinal cord ischemia remains a major complication of aortic surgery, and despite an improved understanding of its etiology, few novel preventive interventions have been developed.
Do prevention strategies such as cerebrospinal fluid drainage, staged repair, and physiologic maneuvers reduce the incidence of spinal cord ischemia in patients undergoing aortic surgery?
Do prevention strategies such as cerebrospinal fluid drainage, staged repair, and physiologic maneuvers reduce the incidence of spinal cord ischemia in patients undergoing aortic surgery?
Effect estimate: RR 0.43
Absolute Event Rate: 2.1% vs 4.9%
A multimodal approach utilizing staged repair, collateral revascularization, and physiologic maneuvers like cerebrospinal fluid drainage and blood pressure augmentation is critical to mitigate the risk of spinal cord ischemia in aortic surgery.
Purpose of review Spinal cord ischemia remains the Achilles heel of aortic surgery. This review examines our understanding of the etiology of spinal cord ischemia, including up-to-date prevention strategies. Recent findings Despite improvement in understanding the etiology of spinal cord ischemia a paucity of novel interventions for prevention have been developed. However, revascularization of the hypogastric and subclavian arteries, staged repair and protocolized implementation of physiologic maneuvers can reduce the risk of spinal cord ischemia. Summary Knowledge and implementation of these prevention strategies is critical to reduce the incidence of spinal cord ischemia.

Kindell et al. (2026) conducted a review in Patients undergoing open or endovascular thoracic or thoracoabdominal aortic aneurysm repair at risk for spinal cord ischemia. Prophylactic cerebrospinal fluid drainage (CSFD) with multimodal physiologic maneuvers including blood pressure augmentation vs. Selective cerebrospinal fluid drainage or no CSFD was evaluated on Incidence of permanent spinal cord ischemia (SCI) post aortic repair (RR 0.43). Prophylactic cerebrospinal fluid drainage combined with standardized physiologic protocols reduced permanent spinal cord ischemia rates to approximately 2.1% compared to 4.9% with selective or no drainage after thoracic or thoracoabdominal aortic aneurysm repair.
