Abstract:
To evaluate the significance and methods of preoperative revealing of the tears of thoracic aortic dissections before endovascular graft exclusion, 32 cases were studied. Among them, 26 cases were evaluated with spiral CT only, 5 with CT and MR together, while one with MR only. Compared with intra operative Digital Subtraction Angiography, the detectable rate of CT,MR and DSA for revealing the tears was 90 32%, 66 7%, and 100% respectively.The most frequently appeared locations of the tears were at the section between 3 and 7 o'clock. In the case of multi entrances, the results evaluated with CT were different from those with DSA. It is concluded that accurate evaluation of the tears would be profitable to stent grafts selection and operative decision, and spiral CT images are most effective in preoperative evaluation of the tears.
