Abstract：Objective To evaluate the value of multi-slice spiral CT angiography（MSCTA）with post-processing image features in the diagnosis of spontaneous isolated dissection of superior mesenteric artery(SIDSMA). Methods MSCTA and post-processing images of 21 SIDSMA patients were reviewed retrospectively. Multiple post-processing techniques were used to analyze the image data such as dissection rupture, true and false lumen, intimal flaps, extent of interbed, branches’affected situation and presence of ischemia. Results In these 21 patients, there were 14 patients had clear ruptures. The distance from the origin of the superior mesenteric artery (SMA) to the tear ranged from 1.4 cm to 5.5 cm. The length of dissection ranged from 5.5 cm to 15.9 cm. There were 14 patients had clear intimal flaps, 18 patients had false lumen thrombosis, 6 patients had pseudoaneurysm of SMA, 3 patients had aneurysmal dilatation of the SMA. 1 patient had dissecting aneurysm ruptured. 17 patients had stenosis of the true lumen, 2 patients had SMA trunk occlusion, 12 patients had SMA branches involvement, and 2 patients had acute small intestinal ischemia. Conclusion MSCTA and image post-processing technique provide clear diagnosis and accurate evaluation of SIDSMA, which are helpful for the choice of clinical therapy.
