Fiber-Optic Navigation During TIPS Creation: A Prospective Pilot Study

Transjugular intrahepatic portosystemic shunt (TIPS) creation is an established minimally invasive treatment for complications of portal hypertension such as refractory ascites and variceal bleeding. A technically challenging step of the procedure is the puncture of the portal vein from the hepatic vein, which is usually performed under fluoroscopic guidance and may require multiple puncture attempts. This prospective pilot study evaluates the use of fiber-optic navigation technology during TIPS creation. The system allows real-time three-dimensional visualization of guidewires and catheters and may improve spatial orientation during the procedure. Approximately 30 patients with a clinical indication for TIPS placement will be included. The study will assess procedural parameters such as the number of puncture attempts, fluoroscopy time, radiation exposure, procedure duration, technical success, and complications. The results may help to improve procedural efficiency and radiation safety during TIPS interventions.

Clinical Study to Evaluate the Efficacy and Safety of Dapagliflozin in Patients With Refractory Cirrhotic Ascites

The aim of this clinical trial is to evaluate the safety and efficacy of low dose dapagliflozin use along with standard care versus the standard care alone in improving the clinical outcomes of patients with cirrhotic refractory ascites. The main question it aims to answer is the difference in ascites control between the two groups at the end of treatment defined as: Complete response: Disappearance of ascites. Partial response: Presence of ascites not requiring LVP. No response: Presence of ascites requiring LVP. Researchers will compare intervention group receiving dapagliflozin 5m once daily for 3 months along with standard care versus standard care group to evaluate the effectiveness and safety of dapagliflozin in refractory ascites patients.
