Abstract
BACKGROUND: The present study retrospectively reviewed and evaluated the effectiveness of thoracic endovascular aortic repair (TEVAR) combined with assistant techniques and devices for the treatment of acute complicated Stanford type B aortic dissections involving aortic arch. METHODS: Fifty-six patients with acute complicated Stanford type B aortic dissection involving aortic arch were treated with TEVAR combined with hybrid procedure, chimney-graft technique, and branched stent grafts from January 2009 to March 2014. RESULTS: Seventeen patients undergone TEVAR combined with hybrid technique. Technical success was achieved in 94.1% with 5.8% of early mortality. Strokes occurred in a patient developing paraplegia, who completely recovered after lumbar drainage. Cardiocirculatory and pulmonary complications, bypass dysfunction or severe endoleak was not observed. Thirty patients undergone TEVAR combined with chimney technique with 100% technical success rate. Chimney-stent compression was observed in 1 patient, and another bare stent was deployed inside the first one. Three patients (10%) died during the study period. Immediate postoperative type I endoleak was detected in 4 cases (13.3%). TEVAR assisted by Castor branched aortic stent grafts in 9 patients was successful. Mortality during perioperative period and 30 days after TEVAR was null. No serious complications such as strokes, acute myocardial infarction, and ischemia of arms occurred. CONCLUSIONS: The results indicate that TEVAR combined with hybrid technique, chimney technique, and branched stent grafts is proven to be a technically feasible and effective treatment for acute complicated Stanford type B aortic dissection involving aortic arch in small cohort.
