Research progress in the application of stent in TIPS procedures

Transjugular intrahepatic portosystemic shunt (TIPS) stands as a pivotal interventional therapy for managing portal hypertension (PH) and its associated complications. Distinguished from pharmacological treatments, endoscopic interventions, or surgical portocaval shunts, TIPS has achieved extensive clinical application attributed to its minimally invasive nature and efficacy. Notwithstanding, complications ensuing from TIPS, such as hepatic encephalopathy (HE) and shunt dysfunction, etc, significantly impact patient prognosis. Over the course of several decades, a diverse array of stent types and diameters have become available for TIPS procedures. Moreover, the stent puncture position and the initial stent position also exhibit variability. Our review aims to address this gap in knowledge by reviewing the research progress on stent types, diameters, puncture positions, and initial stent positions in the context of TIPS. It presents a comprehensive overview of the various stent options available for TIPS procedures and highlights the importance of individualized treatment approaches in reducing surgical complications and improving patient prognosis. The findings outlined in our review provide valuable insights for clinicians and researchers in the field.
