TEVAR for aortic arch lesions combining physician-modified endograft and in-situ fenestration.

BACKGROUND: The aim of this retrospective study was to investigate the outcomes of combining physician-modified endograft (PMEG) and in-situ fenestration (ISF) for aortic arch repair. METHODS: A retrospective analysis was performed in 12 patients with aortic arch pathologies who underwent thoracic endovascular aortic repair with PMEG and ISF between June 2019 and February 2020. RESULTS: Revascularizations of supra-aortic arteries were successfully performed in 91.7% patients (11/12). One patient with aberrant right subclavian artery was unsuccessful because of tortuosity and sharp angle. One patient received endovascular exclusion by Viabahn due to artery injury of the femoral access. During the follow-up (mean 22.7 months), one patient underwent Bentall surgery because of retrograde type A aortic dissection, and one patient received coils embolization due to occurrence of a type I endoleak. In addition, one patient died of myocardial infarction 13 months after surgery. Results obtained after computed tomography angiography confirmed patency of all the supra-aortic arteries. CONCLUSIONS: Combining PMEG and ISF could be a feasible option for aortic arch lesions in selected patients. Long-term durability concerns require further evaluation.
