Abstract

Background: To report the use of the Oscor Destino steerable sheath in challenging target visceral vessel (TVV) cannulation/bridging stenting in fenestrated and branched endovascular aneurysm repair (FB-EVAR). Methods: Between 2016 and 2018, patients undergoing FB-EVAR for juxtarenal/pararenal aneurysms (j/p-AAAs) and thoracoabdominal aortic aneurysms (TAAAs) were recorded. Cases requiring the use of the steerable sheath as planned or unplanned maneuvers were analyzed. Technical success, freedom from reinterventions, and TVV patency were assessed. Results: Two hundred sixty patients underwent FB-EVAR to treat j/p-AAAs and TAAAs, for an overall of 956 TVVs. Among these, the Oscor Destino steerable sheath was used in 33 (13%) cases to cannulate a total of 62 (7%) TVVs. FB-EVAR was performed for 7 (21%) j-AAAs, 4 (12%) p-AAAs, 11 (61%) TAAAs, and 2 (6%) previously failed EVAR. The TVVs were 37 (60%) renal arteries, 9 (15%) superior mesenteric arteries, and 16 (25%) celiac trunks. The Oscor Destino steerable sheath was used as the primary cannulation approach in 29 (47%) cases and after failure of the standard cannulation technique in 33 (53%) cases. Technical success was achieved in 61/62 (98%) TVVs. There was no 30-day mortality or bowel ischemia. At the discharge, there were no type I/III endoleaks, whereas 4 type II endoleaks were detected. The median follow-up was 12 months (interquartile range: 8). One patient died at 6 months because of aneurysm-unrelated cause. No TVV occlusion or TVV-related reinterventions occurred. There were no type I–III endoleaks. Conclusions: The use of the steerable sheath could be an effective adjunctive tool and can be used primarily as a planned technique or in case of failure of the standard cannulation technique in challenging TVV anatomy during FB-EVAR.
