Objective The total SPSS diameter(TSD),Total cross-sectional SPSS area(TSA),and Total SPSS volume(TSV)were measured by imaging methods in patients with spontaneous portosystemic shunting(SPSS),to compare the di-agnostic efficacy for the complications of cirrhosis.Methods A retrospective collection of 107 patients from Shandong U-niversity Qilu Hospital Dezhou Hospital from January 2015 to January 2022 was conducted.TSD,TSA and TSV of shunt veins were measured respectively,and the linear relationship was analyzed.Receiver operating characteristic curves(ROC curves)were constructed to predict hepatic encephalopathy,portal vein thrombosis,gastrointestinal bleeding and ascites based on three measurement methods,and the diagnostic efficiency of the three methods was analyzed and compared.Re-sults No linear relationship was found between TSD with both TSA and TSV(B=0.102,4.176,P＞0.05),but the line-ar relationship between TSA and TSV existed(B=9.585,P=0.015).A total of 46 patients(42.99％)with hepatic en-cephalopathy were diagnosed accurately by TSD,TSA and TSV(AUC=0.797,0.817,0.810),and there was no statistical significance in the diagnostic efficacy of these three methods(P＞0.05).A total of 39 cases(36.45％)with portal vein thrombosis were diagnosed accurately by TSD,TSA and TSV(AUC=0.751、0.873、0.862),and the diagnostic efficacy of TSA and TSV were higher than that of TSD(P＜0.05).A total of 41 cases(38.32％)with gastrointestinal bleeding were diagnosed inaccurately by TSD(AUC=0.581),but were diagnosed accurately by TSA and TSV(AUC=0.761、0.813),and there was no statistically significant difference in diagnostic efficacy between TSA and TSV(P=0.373).A total of 52 cases(48.60％)with ascites were diagnosed inaccurately by TSD(AUC=0.652),but were diagnosed accurately by TSA and TSV(AUC=0.753、0.878),and the diagnostic efficacy of TSV were higher than that of TSA(P=0.049).Conclu-sion Imaging measurement had a high predictive value for the occurrence of cirrhosis complications,with TSA and TSV had high efficacy,while TSD had limited efficacy.Considering the convenience of operation,TSA is a more suitable imaging measurement method.
