Enhancing transjugular intrahepatic portosystemic shunt procedure efficiency with digital subtraction angiography image overlay technology in esophagogastric variceal bleeding

Figure 1 Preoperative and postoperative liver computed tomography scans. This figure illustrates the liver computed tomography scans before and after the transjugular intrahepatic portosystemic shunt procedure in a patient with chronic hepatic schistosomiasis complicated by portal hypertension and esophagogastric varices bleeding. A: The preoperative condition where the left lobe of the liver is significantly enlarged and the right lobe is atrophic, highlighting the exposed portal vein (indicated by an arrow); B: The postoperative scan where a high-density stent, effectively placed within the portal vein, is clearly visible.
