Total aortic arch repair with double-fenestrated physician-modified fi ed endografts, at least 3-year follow-up

Objective: This study aims to report the efficacy fi cacy and safety of double-fenestrated physician-modified fi ed endovascular grafts (PMEGs) for total aortic arch repair with at least 3 years of follow-up. Methods: All consecutive patients with a pathological aortic arch who underwent aortic arch repair combined with a homemade double-fenestrated stent graft from 2017 to 2020 were reviewed. Results: 74 patients were treated for pathological arch conditions with a double-fenestrated PMEG. Of these, 81% were male, the mean age was 69.9 years, and 59% were classified fi ed as American Society of Anesthesiology 3 or 4. Thirty-five fi ve percent were treated for a postdissection aneurysm, 36% for a degenerative aneurysm, and 14% for acute type B dissection. Fifteen percent had supra-aortic trunk dissection. Fenestration on the subclavian artery was performed in 96%; if not, a carotid-subclavian bypass was carried out. Technical success was 100%. The proximal landing zone is consistently in zone 0. Early outcomes revealed a 3% occurrence of type 1 endoleak, which was successfully treated by prompt reintervention. One retrograde dissection occurred, and one patient died from hemorrhage on an iliac conduit. A 5% stroke rate was reported. During long-term follow-up (mean time 40.7 months), one type 1 endoleak appeared and was successfully treated; no type 2 or type 3 endoleak requiring intervention occurred. No stent fractures or migrations were reported. Four percent of patients required reintervention, but no surgical conversion to open surgical repair was needed on the aortic arch. No patient died from a cause related to the main procedure. Conclusions: Total aortic arch repair with double-fenestrated PMEGs is associated with acceptable early and midterm major morbidity and mortality. It is suitable for the main aortic pathologies. Moreover, it is easily available for emergency situations. (J Vasc Surg 2024;80:344-54.)
