Abstract:
Objective To summarise the clinical experience on the treatment of aortic dissection with stent-graft. Methods From June 2005 to November 2008, 117 patients with aortic dissection underwent surgery with stented elephant trunk (CRONUS stent-graft)which was implanted through the aortic arch under deep hypothermic circulatory arrest, including Stanford A in 50 patients who underwent Bentall operation and total arch grafting with stented elephant trunk operation in 28, Wheat operation and total arch grafting with stented elephant trunk operation in 8, ascending aorta and total arch replacement with stented elephant trunk operation in 14 and Stanford B in 67 patients who all underwent stented elephant trunk operation. Results The location of the entry was in the ascending aorta in 35 patients, the aortic arch in 4, the proximal descending aorta in 78. Cardiopulmonary bypass time was ( 159 ±31 ) min, average cross clamp time was (95 ±23) min, and average selected cerebral perfusion and lowerbody arrest time was (27 ±8) min. The in-hospital mortality was 2.6% (3/117). One patient died of the hemorrhage shock, one died of multi-organ failure postoperatively and the third died of infective endocarditis. The complications included transient neurologic deficit in 11(9.4%), cerebrovascular accident in 6 (5. 1%, cerebral embolism in 2 and cerebral hemorrhage in 4, of which 5 cases were discharged from hospital. One case died of multiorgan failure 18 days after discharge owing to his family' s giving up treatment), hemorrhage of anastomose which was treated by reoperation in 5,hoarseness in 2, renal failure in 1. One case died of the cerebral hemorrhage after 4 months due to inappropriate anticoagulation during following up. Conclusion The treatment of the aortic dissection with stent-graft which was implanted into the descending aorta through aorta arch is safe, effective and feasible, which will be helpful to vascular reconstruction by accurately close subintimal rip and can streamline surgery with minimally invasive and less complications.
