Objective:To evaluate the methods and results of endovascular therapy for Stanford type B aortic dissection.
Methods :A retrospective review was conducted of 158 patients with Stanford type B aortic dissection who were treated with endovascular therapy in the past six years. There were 19 cases of emergency operation and 139 cases of elective operation. Fellow-up was performed regularly after operation. Aortas were dynamically observed.
Results:After the stent-graft implantation, 92.4% blockade rate of the first tear of the Stanford type B aortic dissection was obtained.After operation, 22 cases were complicated by hemothorax,13 cases by ischemia of superior mesenteric artery,9 cases by acute renal insufficiency, and 5 cases by ischemia of artery of lower extremity. Three cases of huge chronic dissection aneurysm achieved clinical cure after operation. No subclavian steal syndrome occurred in the 19 cases whose left subclavian artery was sealed by the stent-graft during operation. There was no hospital death.One hundred and forty-one cases were followed up for 3～48 months. Continuous endoleaks were found in 2 cases; 1 case of the stent-graft migration was successfully treated after another stent-graft implantation; and 1 case of cerebral arteries infarction recovered well.
Conclusions:Endovascular therapy is safe and effective for the patients with Stanford type B aortic dissection in the early and mid-term periods of postoperation.
