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.

Figure 2 Digital subtraction angiography image overlay technology-assisted hepatic artery labeling for guided transjugular intrahepatic portosystemic shunt procedure. This figure demonstrates the steps involved in a transjugular intrahepatic portosystemic shunt procedure utilizing digital subtraction angiography (DSA) image overlay technology. A: The simultaneous visualization of the hepatic artery and its adjacent portal vein facilitated by DSA image overlay technology, enabling precise navigation and planning for the procedure; B: The hepatic artery after it has been catheterized and labeled, which serves as a crucial guide for accurate portal vein puncture; C: The portal vein post-catheterization, where angiography confirms that the esophagogastric varices have been fully embolized; D: The final placement of the portosystemic stent with visible spring coils within the embolized esophagogastric varices, indicating successful implementation of the shunt.
