Transjugular intrahepatic portosystemic shunt (TIPS) offers a minimally invasive option for managing portal hypertension complications. Careful follow-up is crucial due to potential risks like encephalopathy and shunt stenosis.

Area of Science:

  • Interventional Radiology
  • Hepatology
  • Gastroenterology

Background:

  • Portal hypertension complications necessitate advanced management strategies.
  • Transjugular intrahepatic portosystemic shunt (TIPS) is a recently introduced procedure for managing these complications.

Purpose of the Study:

  • To review the indications, complications, and follow-up requirements of TIPS procedures.
  • To evaluate the efficacy of TIPS in managing acute variceal hemorrhage, recurrent bleeding, and refractory ascites.

Main Methods:

  • Review of existing literature and clinical data on TIPS procedures.
  • Analysis of complication rates, including infection, hemorrhage, encephalopathy, and shunt stenosis.
  • Assessment of follow-up protocols involving ultrasonography and angiography.

Main Results:

  • TIPS placement is technically feasible with low mortality by skilled radiologists.
  • Major complications include infection, hemorrhage, encephalopathy (more common in older patients with wide shunts), and shunt stenosis (linked to pseudo-intimal hyperplasia).
  • Regular follow-up is mandatory to monitor for shunt stenosis and manage encephalopathy.

Conclusions:

  • TIPS is primarily indicated for acute variceal hemorrhage, prevention of recurrent bleeding, and refractory ascites unresponsive to conventional therapy.
  • The long-term role of TIPS in portal hypertension management requires further validation through clinical trials.
  • Close patient monitoring is essential to mitigate risks associated with TIPS procedures.
