Abstract

Objective To analyze the 128 slice CT angiography findings of spontaneous isolated superior mesenterric artery dissection(SISMAD).Methods Eight cases of SISMAD were enrolled in the study.The CT findings and optimal post processing method were analyzed retrospectively.Results The length of SISMAD ranged from 10mm to 75 mm.SISMAD located at the proximal segment of SMA in 7 cases,10-30 mm from the site of SMA in 3 cases,located at the inferior pancreaticoduodenal artery in 1 case.More than 3 teared ruptures of SISMAD were found in 5 cases,two ruptures in 1 case,one rupture in 2 cases.Thrombosis was found in partial false lumen.Conclusion Pathological changes of SISMAD were showed clearly on CTA,128 slice CTA can be used as the first choice method in diagnosing SISMAD.
