Staged Hybrid Approach to Chronic Type B Aortic Dissection Involving the Distal Arch Associated with Aortic Root Aneurysm

Abstract

Open surgical repair of complex aortic pathologies using cardiopulmonary bypass and deep hypothermic circulatory arrest still carries a substantial rate of mortality and morbidity. Endovascular stent-graft placement has developed as a safe and effective treatment modality for various diseases of the aorta. We report on the case of a 65-year-old female presenting with symptomatic type B aortic dissection with aneurysm of the ascending aorta and the aortic root. The patient was treated with a flanged composite graft custom made from a branched 24-mm Dacron graft for entire prosthetic transposition of the supra-aortic branches. Metachronously, the patient underwent endovascular stent-grafting of the descending aorta. She was discharged free of complications on day 10.
