多层螺旋CT对胰源性区域性门静脉高压的诊断价值(附42例报道)

Objective To analyze MSCTfeatures of PSPHand to evaluate the value of MSCT in clinical settings and imaging diagnosis of PSPH.Methods A 16-detector row spiral CT scanner was used to perform plain and muti-phase contrast enhanced abdominal scanning in 42 patients with PSPH.Various image post-processing techniques were applied to depict abnormal splenic vein and the collateral vessels of PSPH.Results In 30 cases with isloated splenic vein occlusion, esophageal vein (EV, 9.5%) , coronary gastric vein (CGV, 76.19%) , short gastric vein (SGV, 85.71%) gastroepiploic vein (GEV, 95.24%) and gastrocolic trunk (GCT, 23.81%) were varicose and dilated, respectively.In 12 non-isloated splenic vein occlusion, associated with 8 cases SMV occlusion, other collateral veins such as gastrocolic trunk (GCT, 19.05%) , the right superior colic vein (RSCV, 16.67%) , middle colic vein (MCV, 14.29%) and anterior superior pancreaticoduodenal vein (ASPDV, 19.05%) were seen as well.Meanwhile 5 cases assoicated with cavernous transformation of portal vein.Conclusion MSCT and image post-processing techniques are of great value for the diagnosis of PSPH in Splenic vein occlusion and collateral vessels around.
