Abstract: Objective The aim of this study was to summarize the feature spontaneous splenorenal shunts (SSRS) diagnosed by abdominal contrast-enhanced CT scan and CT portal venography (CTV) in patients with liver cirrhosis (LC). Methods A total of 131 patients with LC were admitted to our hospital between December 2022 and January 2025, all patients underwent CT scan, and post-processed by multiplanar reconstruction,maximum intensity projection and volume reconstruction. Results Of the 131 patients with LC, SSRS was found in 29 cases (22.1%); incidence of esophagogastric varices, diameters of splenic vein and superior mesenteric vein in SSRS group were 82.8%, (1.2±0.3)cm and (1.1±0.2)cm, all significantly higher or greater than [62.7%, (1.0±0.3)cm and (0.9±0.2)cm, respectively, P<0.05], while diameters of main portal vein, left and right branches were (1.2±0.3)cm, (0.8±0.2)cm and (0.8±0.2)cm, all significantly smaller than [(1.4±0.3)cm, (1.0±0.3)cm and (0.9±0.2)cm, respectively, P<0.05] in non-SSRS group; multivariate Logistic regression analysis showed that diameter of splenic vein (OR<0.001), diameter of main portal vein (OR=0.003), diameter of right branch of portal vein (OR=0.025) and diameter of superior mesenteric vein (OR=0.008) were all the independent risk factors for SSRS occurrence. Conclusion CTV could help find SSRS existence in patients with LC, and its impact on clinical outcomes needs further investigation.
