Spinal Cord Ischemia (SCI) after Endovascular Repair (EVAR) of the Thoracoabdominal Aorta

Paraplegia is a recognized complication after endovascular stent repair of descending thoracic aortic aneurysms. Interventions to augment spinal cord perfusion are effective for avoiding or decreasing paraplegia. Clinical Findings or Procedure Details: SCI occurs 3–12% with EVAR of thoracoabdominal aorta and there is a higher rate of spinal cord ischemia in patients with previous/concomitant AAA repair. Compared to open surgery EVAR shows lower risk factor of spinal cord ischemia because e.g. neither there is need for proximal hypertension due to clamping nor segmental arteries are re-implanted and reperfusion i…
