Hybrid Endovascular Repair of Thoracic Aortic Aneurysms by Debranching and the Creation of Landing Zone-zero

Thoracic aortic aneurysms (TAA) have remained a formidable operative challenge. Open surgical techniques have been associated with high rates of morbidity and mortality. Thoracic endovascular aneurysm repair (TEVAR) has produced results equal to or better than the traditional open surgical approach. This report presents a patient with a complex thoracic aortic aneurysm involving the ascending, transverse, and proximal descending thoracic aorta. This patient was successfully managed by the creation of Landing Zone-Zero, arch vessel debranching, and endografting the entire aortic arch without the need for hypothermic circulatory arrest or cerebral perfusion strategies. Computer tomographic images demonstrate the repair to be durable at 18 months.
