Single- and Double-Fenestrated Physician-Modified Stent Grafts for Emergent Aortic Arch Lesions

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.
