Staged Hybrid Repair to Reduce the Risk of Spinal Cord Ischemia After Extensive Thoracic Aortic Aneurysm Repair

Area of Science:

• Cardiovascular Surgery
• Vascular Surgery
• Neurosurgery

Background:

• Extensive thoracic aortic aneurysms pose significant risks, including spinal cord ischemia.
• Current repair strategies may not adequately protect spinal perfusion.
• Staged repair offers a potential solution to mitigate these risks.

Observation:

• Seven patients with extensive thoracic aortic aneurysms underwent staged hybrid repair (2-3 stages).
• The strategy involved maintaining adequate spinal artery flow and allowing interval distal type I endoleak.
• This approach aimed to preserve spinal perfusion during the vulnerable early postoperative period.

Findings:

• The 30-day mortality rate was 0%.
• The incidence of spinal ischemia was 0%.
• Staged repair facilitated structural remodeling of spinal cord vasculature.

Implications:

• Staged hybrid repair is a viable strategy for extensive thoracic aortic aneurysms.
• This technique may significantly reduce the risk of spinal cord ischemia.
• Further research is warranted to validate these findings in larger cohorts.
