Outline the mechanism of action and list the indications, contraindications and complications of the TIPSS procedure (Transjugular intrahepatic portosystemic shunt).
Mechanism of action:
Percutaneous formation of a tract between hepatic vein and intrahepatic segment of portal vein. Blood is shunted away from portal circulation to systemic circulation, thereby reducing portal pressure.
Indications: (20% Marks)
Contraindications (1 mark/point to max 4 points) (30% marks)
Complications: (50% marks)
