CONCLUSIONS: Parallel grafting presents a safe, efficacious and off the shelf alternative to conventional repair of complex aortic aneurysms involving the visceral aorta. Copyright (c) 2021. Published by Elsevier Inc. INTRODUCTION: Parallel grafting presents a viable method for treating patients with complex aortic aneurysms. The current literature is limited to mostly pararenal configurations. We examined our results in patients with SMA/Celiac artery involvement. METHODS: A retrospective analysis was performed for all patients undergoing parallel grafting during the period of 2014 to 2018 at a single institution. All patients had at least SMA with/without Celiac artery parallel grafting. RESULTS: Seventy-nine patients (65% male, median age 74) were treated with 208 parallel grafts. Median ASA1 score is 4. Forty-nine cases were elective, 22 urgent, and 8 emergent. Mean pre-operative aneurysm diameter was 7.1cm (4.6-15cm). Self-expanding covered stents were used for the renal arteries (mean 6.3mm), and balloon-expandable covered stents were used for the SMA and Celiac (mean SMA 8.6mm, mean celiac 8.3mm). Axillary exposure was the choice of access in 68 patients (86%). Technical success was achieved in all cases. We defined this as aneurysm sac exclusion with patent visceral stent grafts, and absent to mild gutter leaks. Mean aortic graft proximal seal achieved was 48mm. Coverage extended above the celiac artery in 75% (10% stented and 65% covered). Median contrast volume was 145ml, operative duration was 4 hours, fluoroscopy time was 56min, and EBL was 250ml. Peri-operative mortality was 6.1%. 4.5%, and 25%, for the elective, urgent, and emergent groups, respectively. There was no incidence of spinal cord ischemia. Axillary access was complicated in 4 patients, requiring patch closure of the axillary artery. One patient developed postprocedural ESRD from a rupture and ATN despite patent renal stents. Of those patients with a patent GDA and celiac coverage, two required a cholecystectomy. Nine patients had a persistent gutter leak at the conclusion of the procedure. Median follow-up was 12 months. On follow-up imaging, all SMA and Celiac stents were patent. Six renal stents were occluded and 2 patients progressed to ESRD, both solitary renal periscope configurations at the index procedure. Only 4 patients had persistent gutter leaks with 2 requiring reintervention. Ninety-five percent of patients demonstrated sac regression or stabilization with a mean sac size of 6.5cm.
