OBJECTIVE: To evaluate and compare outcomes of single- and double-fenestrated physician-modified endovascular grafts (PMEGs) for aortic arch pathologies treated in an emergent setting.
METHODS: All patients consecutively treated for an emergent aortic arch pathology were included in this retrospective single-center cohort study between July 2014 and March 2023. In each case, the distal smaller fenestration for the left subclavian artery (LSA) was the only 1 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 86 patients with complicated aortic arch lesions were treated, with 74% being men and a mean age of 68 years. Of these, 63% underwent single LSA fenestration, while 37% had double-fenestrated thoracic endovascular aortic repair. The main indications for repair included acute complicated type B aortic dissection (TBAD) (54%), traumatic transection of the aorta (TTA) (19%), and other conditions such as penetrating aortic ulcer (PAU), degenerative aneurysm (DA), pseudoaneurysm (PSA), and aortic thrombus. The technical success rate was 91%, with modification times of 10 minutes for single fenestration and 23 minutes for double fenestration. Thirty-day mortality was 19%, with no significant difference between the 2 fenestration types. Neurologic events occurred in 3 patients (3%), and 3 (3%) patients had perioperative retrograde dissection. Endoleaks occurred in 5% (type 1) and 2% (type 3), with no type 2 endoleaks. Eight patients (9%) required reintervention, and all supra-aortic trunks remained patent. During a follow-up of 27.6 months, no patients experienced aortic rupture (AR), neurological events, or required conversion to open surgery.
CONCLUSION: Single and double PMEGs are suitable and reproducible treatment for emergent serious aortic arch lesions, with comparable outcomes whatever the aortic landing zone and number of fenestrations.Clinical ImpactFenestrated physician-modified endovascular grafts for emergent aortic arch repair appear to be a promising treatment, offering reproducibility, rapid deployment, and limited manipulation of supra-aortic trunks. The standardized technique eliminates the need for complex sizing and benefits from consistent aortic arch anatomy in most patients. It provides clinicians with a practical and efficient option in emergency settings, achieving high technical success with acceptable complication rates.
