Hybrid thoracoabdominal aortic aneurysm repair: current perspectives

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine
• Medical Technology

Background:

• Open repair of thoracoabdominal aortic aneurysms (TAAAs) carries high morbidity and mortality.
• Complications include respiratory failure, heart failure, renal failure, and spinal cord ischemia.
• The hybrid approach aims to reduce physiologic stress by combining open visceral bypass with endovascular repair.

Purpose of the Study:

• To evaluate the outcomes of a hybrid technique for TAAA repair.
• To assess the feasibility and safety of visceral debranching followed by thoracic endovascular aneurysm repair (TEVAR).
• To compare the hybrid approach's outcomes with traditional open repair, considering patient comorbidities.

Main Methods:

• Retrospective review of 18 hybrid TAAA repairs performed between 2006 and 2010.
• Inclusion of visceral debranching followed by endovascular aortic repair.
• Analysis of 30-day mortality, visceral graft patency, and spinal cord ischemia rates.

Main Results:

• Thirty-day mortality was 11.1%.
• Thirty-day visceral graft patency was 94.4%.
• Spinal cord ischemia occurred in 11.1% of patients.

Conclusions:

• The hybrid approach may reduce mortality and morbidity, particularly spinal cord ischemia, in TAAA patients.
• Further standardization of the staged approach and long-term graft patency data are needed.
• Preoperative comorbidities significantly influence patient outcomes.
