RS09. The Fundamentals of Vascular Surgery: A 6-Year Review of the First U.S. Dedicated Vascular Simulation Course

Abstract

the TEVAR group and 8.3% (7 of 84) in the STABLE group (P ¼ .22). The 30day rate of malperfusion-related mortality (deaths from bowel/mesenteric ischemia or multiple organ failure) was 12% (5 of 41) in the TEVAR group and 2.4% (2 of 84) in the STABLE group (P ¼ .038). Thirty-day morbidity, for the TEVAR and STABLE groups, respectively, included bowel ischemia (9.8%, 4 of 41 vs 2.4%, 2 of 84; P ¼ .09), renal failure requiring dialysis (7.3%, 3 of 41 vs 9.5%, 8 of 84; P > .99), paraplegia or paraparesis (4.9%, 2 of 41 vs 3.6%, 3 of 84; P ¼ .66), and stroke (2.4%, 1 of 41 vs 11%, 9 of 84; P ¼ .16). The occurrence of 30-day secondary intervention was similar in the TEVAR and STABLE groups (7.3%, 3 of 41 vs 7.1%, 6 of 84; P > .99). Conclusions: In patients with acute type B aortic dissection in the setting of branch vessel malperfusion, the use of a composite device with proximal stent grafts and distal bare aortic stent seemed to result in lower malperfusion-related mortality than the use of stent grafts alone. Thirty-day rates of morbidity and secondary interventions were similar between the groups.
