Abstract
This study aimed to evaluate the efficacy and safety of a handmade fenestrated stent graft over an aortic stent graft for preserving the left subclavian artery (LSA) in thoracic endovascular aortic repair (TEVAR). From July 2015 to October 2018, a total of 32 consecutive patients with various thoracic aortic pathologies who underwent TEVAR in which handmade fenestration over a thoracic aortic stent graft was used for LSA were included. Outcomes including technical success, procedure-related complications, perioperative mortality and morbidity and graft patency were analysed. Twenty-four patients (75.00%) presented with aortic dissection, 5 patients (15.63%) with thoracic aortic aneurysm and 2 patients (6.25%) with penetrating aortic ulcer; 1 patient (3.13%) required re-TEVAR due to endoleak and sac expansion from previous TEVAR for thoraco-abdominal aneurysm. TEVAR was performed in a zone 2 landing with single fenestration for LSA (26 patients, 81.25%), zone 1 landing with double fenestration for both LSA and left common carotid artery (5 patients, 15.63%) or zone 1 landing with single fenestration for LSA and a chimney graft for left common carotid artery (1 patient, 3.13%). The technical success rate, defined as the successfu...Continue Reading
