  Objective Analysis and evaluate the performance of celiac axis stenosis and collateral circulation by multislice spiral CT angiography.Methods Retrospective analysis of celiac axis stenosis 30 cases,23 males and 7 females,average age 53.7 years,diagnosised by MSCT threedimensional reconstruction.All the cases were not indicated celiac clinical history of vascular disease.Transport all the image data to CT workstation for CT angiography reconstruction analysis,including maximum intensity projection(MIP)and volume rendering(VR).Evaluation of stenosis of the celiac axis,respectively the extent,collateral circulation,and the presence of concurrent aneurysm,or the superior mesenteric artery stenosis.Celiac collateral circulation is divided into four types: pancreaticoduodenal arcades type,dorsal pancreatic artery type,intrahepatic type,and inferior mesenteric artery type.Results Celiac initial segment of 30 patients are stenosis,the degree of stenosis 45%-95%.22 cases with collateral circulation(73.3%,22/30),a total of 28 lateral transport,including 17(60.7%,17/28)with pancreaticoduodenal arcades type,6(21.4%,6/28)with dorsal pancreatic artery type,one(3.6%,1/28)with intrahepatic type,4(14.3%,4/28)with inferior mesenteric artery type.8 patients without collateral circulation(26.7%,8/22).Of 30 patients,four patients with superior mesenteric artery stenosis,and three with abdominal aneurysm.Conclusion Multislice Spiral CT Angiography can accurately diagnose and evaluate the stenosis of celiac axis and collateral circulation or abdominal aneurysm,and has important clinical value.
