Experience with physician-modified Ankura™ endografts for endovascular repair of thoracoabdominal aortic aneurysms

BACKGROUND: The aim of this study was to evaluate the early results of fenestrated/branched endovascular aortic repair (F/B-EVAR) of thoracoabdominal aortic aneurysms (TAAAs) using physician-modified Ankura (TM) endografts (PMEGs). METHODS: Sixteen consecutive patients who underwent F/B-EVAR using PMEGs between July 2017 and December 2018 were retrospectively reviewed. The perioperative mortality and morbidity of the PMEG technique were assessed, and the early results of follow-up were evaluated. RESULTS: The median age of the patients was 75.3 years old (range: 48-83 years), and 12 (75.0%) patients were male. The median TAAA diameter was 7.1 +/- 1.5 cm (range: 5.1-11 cm). The initial technical success rate of vessel revascularization was 98.2% (55 of 56). Target vessel patency was 98.1% (52/53), and freedom from reintervention was 98.1% (52/53) at follow-up. The 30-day mortality rates 6.3%. There was no death during follow-up. CONCLUSIONS: PMEGs represent an important innovation. with favorable initial results, in the treatment of patients with complex TAAAs who may be unfit for open repair. In addition, they remain a promising option for high-risk patients in need of urgent repair who cannot wait for a custom-made device.
