【Abstract】 Objective To evaluate the curative effect of coated stent-graft placement in the treatment of the Stanford type B thoracic aortic dissection. Methods The data of 9 cases diagnosed to be Stanford type B thoracic aortic dissection by CT,MR,IADSA had been analyzed. The conditions of post-operation and follow-up had been evaluated. Results In the 9 cases, 3 patients had been treated with interventional therapy and had been finished successfully only one time,and each one underwent placement of stent graft.Two patients had been verified no endoleak, and a slight typeⅠendoleak had been found in 1 patient by post-operation angiography. One residual shunts disappeared, and no new endoleak occurred in the three patients. The interventional therapy was given up in one patient because the guide-wire could not be reached the abdominal aortic through the real cavity of the thoracic aortic, and in another patient because of the severe aortic distort. Conclusion Interventional therapy of Stanford type B thoracic aortic with coated stent-graft is a safe, effective, less invasive method. Its recent and middle term effect is satisfactory, the succes rate is high, complication rate is low. Further observations are necessary for long term result with a large sample.更多还原
