Efficiency of modified triple-branched stent graft in type I aortic dissection: two-year follow-up

Abstract Background The efficacy of hemiarch replacement combined with a modified triple-branched stent graft in Debakey type I aortic dissection remains to be confirmed. Methods From January 2016 to December 2017, 167 patients with acute Debakey type I aortic dissection underwent hemiarch replacement combined with a modified triple-branched stent graft. The clinical and imaging data were retrospectively analyzed. The early composite endpoint was defined to comprise perioperative mortality, permanent neurological deficits, and renal failure requiring hemodialysis at discharge. Results The overall 30-day mortality was 4.2% (7/167). The incidence of the composite endpoint was 11.4% (19/167). The risk factors for the composite endpoint were malperfusion syndrome (odds ratio [OR], 5.17; 95% confidence interval [CI] 1.46-18.35, P=0.011) and Creatine > 1.5 mg/dl (OR, 5.44; 95% CI 2.27-13.06, P Conclusions Hemiarch replacement combined with a modified triple-branched stent graft is a reliable technique for acute Debakey type I aortic dissection as indicated by two years’ follow up.
