    Abstract:
    OBJECTIVE: We evaluated the early- and medium-term outcomes of single- and double-fenestrated physician-modified endovascular grafts (PMEGs) for total endovascular degenerative aortic arch aneurysm repair. METHODS: We performed a single-center, retrospective analysis of prospectively collected data from 52 patients from August 2013 through January 2021 who had undergone homemade fenestrated thoracic endovascular aortic repair for degenerative aortic aneurysms. In all cases, a distal smaller fenestration for the left subclavian artery (LSA) was fashioned and was the only one stented. For a double-fenestrated endograft, a proximal larger fenestration that incorporated both the brachiocephalic trunk and the left common carotid artery was added. RESULTS: A total of 52 patients with degenerative aortic arch aneurysms were treated. Of the 52 patients, 36 were men, the mean age was 75 ± 8 years, 31% had received a single LSA fenestration, and 69% had undergone double-fenestrated thoracic endovascular aortic repair. Of the 52 procedures, 5 (10%) were emergent procedures. The technical success was 100%. The median time required for stent graft modification was 22 ± 6 minutes. The 30-day mortality was 2% (n = 1). Five patients (10%) had experienced a cerebrovascular event, including two transient ischemic attacks, one minor stroke with full neurologic recovery, and two with sequelae. Two patients (4%) had experienced perioperative retrograde dissection during follow-up. No patient had developed a type I, II, or III endoleak from the LSA. No patient had required reintervention. All supra-aortic trunks were patent. During a mean follow-up of 18 ± 11 months, no patient had required conversion to open surgical repair, aortic rupture, or paraplegia. CONCLUSIONS: Single or double PMEG is a safe and suitable tool for the treatment of high morbidity pathology such as aortic arch degenerative aneurysm repair. In addition, this device can be used in patients requiring elective or emergency repair.
