Abstract
Objective:To explore the applied value of MSCTA in the diagnosis of acute embolism of SMA and SMV .Methods :To analyze the emergent CTA and three-dimensional reconstruction images of 13 cases with acute embolism of SMA and SMV proved by operation and clinic retrospectively .All patients underwent emergent full abdominal plain CT scan and CTA scan ,and the CT scan and CTA were analyzed independently .Results:In 13 cases ,7 cases with SMAE ,and 6 cases with SMVE .Straight-forward signs :2 cases with thrombosis on CT scan in SAME ,all cases with filling defect on CTA ;4 cases with thrombosis on CT scan in SMVE ,all cases with filling defect on CTA .Indirect signs :abdominal effusion(n=6) ,intestinal obstruction(n=5);SMAE (n=7):vessel wall calcification (n=5) ,paper-thin changes of intestinal wall (n=2) ,edema and thickening of the intes-tinal wall with weakened enhance (n=3) .SMVE (n=6):Venous wall ring-sharped enhancement and vascular expansion (n=5) ,vascular“cable”-like changes(n=4) .The involved bowel and mesentery were extensive edema and thickened ,and with ob-vious or weakened enhanced features ,inhomogeneous attenuation in liver parenchyma in portal vein phase (n=2) .Portal vein and splenic vein were involved by thrombus in 2 cases .Conclusion:CTA has higher sensitivity than CT scan on the diagnosis of SMAE and SMVE ,patients with negative signs on CT scan underwent CTA examination is very valuable.关键词
