Feasibility of computed tomography portal venography in the preoperative evaluation of emergent TIPS creation for cirrhotic patients with acute variceal bleeding

To evaluate the feasibility of computed tomography portal venography (CTPV) in the preoperative evaluation of emergent transjugular intrahepatic portosystemic shunt (TIPS) creation for cirrhotic patients with acute variceal bleeding (AVB).One hundred and forty-eightcirrhotic patients with AVB undergoing emergent TIPS creation from January 2016 to December 2022 in our institution were enrolled in the retrospective study. The primary outcome was the consistency between CTPV and endoscopy in the classification and grading of gastroesophageal varices (GEVs). The second outcome was extraluminal CTPV findings. The consistency of CTPV and endoscopy in the classification and grading of GEVs was determined by Kappa values.Emergent TIPS creation was technically successful in all patients. Forty-five patients underwent preoperative endoscopy. The results of CTPV diagnosis of GEVs classification were that 112, 28, and 8 patients were classified as gastroesophageal varices type 1 (GOV1), GOV2, and isolated gastric varices type 1 (IGV1), respectively. In diagnosing the classification and grading of GEVs, CTPV showed substantial agreement with preoperative endoscopy, with Kappa values of 0.823 and 0.625, respectively. CTPV provided the afferent and afferent vessels of GEVs for emergent TIPS creation.CTPV is feasible and effective to act as an alternative preoperative evaluation method to endoscopy for cirrhotic patients with AVB undergoing emergent TIPS creation.
