An ambulatory, vascular surgery office-based approach to bariatric artery embolization

Bariatric artery embolization (BAE) is a minimally invasive therapy for obesity that has primarily been described with postprocedural inpatient monitoring. Whether this procedure can safely be performed without mandatory inpatient monitoring remains unknown. We, therefore, herein report on a retrospective case series evaluating the safety and feasibility of BAE in an ambulatory, vascular surgery office-based setting. As such, six consecutive patients with class II obesity or greater underwent BAE at a single QUAD A-accredited office-based laboratory between December 2024 and August 2025. Five patients were female with a median age of 71 (range, 50-82) and a median body mass index of 42.6 (range, 35.2-49.3). Technical success, defined as cessation of flow within the targeted gastric fundal arteries on completion angiography, was achieved in all. Procedural success, defined as same-day discharge without unplanned hospitalization, was achieved in all. No adverse events of Society of Interventional Radiology grade 1 or higher were observed during the median follow-up duration of 9 months (range, 4-15 months). These findings suggest that BAE can be performed safely and feasibly in an ambulatory, office-based setting in appropriately selected patients, supporting further prospective evaluation of the outpatient BAE model.
