ABSTRACT

Objective To explore the misunderstanding and comprehension of hybrid operation for treating aortic dissection involving aortic arch.Methods From March 2009 to November 2013,13 patients received hybrid operation for aortic dissection involving aortic arch in the People's Hospital of Xinjiang Urgur Autonomous Region were enrolled,including male 11 and female 2,and aged 36 ～ 60 years old with a mean age (44 ± 6.8) years old.All patients were type-B aortic dissection.All of them were not suitable to be treated with endovascular exclusion monotherapy.The ascending aorta-brachiocephalic artery bypass and left carotid artery bypass was established with median sternotomy approach and neck incision in 13 patients,and 2 patients did left subclavian artery bypass additionally,then retrograde endovascular stent graft implantation was used.Computed tomography angiography (CTA) scanning at 3-month,9-month,1-year and every-year after operation showed no stent grafts translocation and bypass graft obstruction.Results The surgical operation and stent grafts implantation were completely successful.Angiography showed 1 case had end leakage and other cases no obvious displacement or end leakage of stent grafts in operation.Blood flow in true lumen of aortic dissection was recovered and all of bypass grafts were unobstructed.No death and severe complications occurred.All patients were followed-up with 3 to 56 months [(29.0 ± 10.2) months],and all patients resumed normal life.Enhanced CT scanning after operation showed 1 case had endoleak and other cases no endoleak,stent grafts translocation and bypass graft obstmction.No signs of brain and limb ischemia were observed.Conclusions To summarize misunderstanding and experience by continuous explore feature of hybrid operation for treating disease involving aortic arch,we developed a more reasonable surgical treatment options that can improve the success rate of complex aortic dissection surgery,and ultimately achieve better surgical results.
