Abstract:
Objective To estimate the application value of dual-source CT on preoperational evaluating new type of three branches aortic arch covered stent graft implantation on DeBakey type I aortic dissection.Methods 20 cases with DeBakey type I aortic dissec-tion prepared to performe three branches aortic arch covered stent graft implantation were reviewed,and their CT findings were ana-lyzed in order to evaluate the guiding value for operation.Results The location and size of entries were determined and the diameter of aortic arch and three branchesas well as the intervals of three branches were also measured by dual-source CT.Furthermore, blood-supply for main vessel and complications related with covered stent were further analyzed prior to operation.The surgical pro-tocols were designed according to preoperational CT findings.Among all cases,13 cases were fit for new type of three branches aor-tic arch covered stent graft implantation.While the rest cases (N=7)were adopted other operations due to non-fitted indications. Conclusion Dual-source CT is of significance for preoperational evaluating new type of three branches aortic arch covered stent graft implantation on DeBakey type I aortic dissection.
