RESUMO
Objective To evaluate the methods,applicability and results of cndovascular therapy for Stanford type B aortic dissection.Methods The clinical data of 36 cases of Stanford type B aortic dissection were analysed retrospectively.The stent-grafts were introduced via femoral arteriotomy.Stent-grafts were implanted to blockade tears of aortic dissection under the guidance of DSA.Results In all cases,the aortic dissection tears were blockaded,true lumens were opened,and organs function was restored.There were not complications such as internal hemorrhage due to trauma or stent displacement on CTA 3 and 12 months after endovascular therapywhile 2 cases developed new tears.The caliber of the 36 true lumens was restored to near normal.Twenty-two pseudocoeloms were obliterated,while the others were reduced is size and had varying degrees of thrombosis.Conclusions Endovascular thcrapy is safe and effectivc for the patients with Stanford type B aortic dissection.Its clinical application has a favorable outlook.
