Liver and biliary interventional procedures

There is a wide range of liver and biliary interventional procedures, both diagnostic and therapeutic, most commonly using CT-guidance or ultrasound-guidance.  

Vascular Interventions:

• transjugular intrahepatic portosystemic shunt (TIPS)

• transjugular liver biopsy (TJLB)

Percutaneous interventions: 

• liver biopsy (US and CT-guided)

• collections/abscess drainage

  • ultrasound guided

  • CT guided

• transhepatic biliary interventions

  • ​​percutaneous transhepatic cholangiography (PTC) 

  • percutaneous transhepatic biliary drainage (PTBD)  

  • percutaneous cholecystostomy (PC)

Interventional oncologic therapeutic procedures:

• transarterial tumor embolization: a method that promotes tumor destruction through a combination of embolization of its supplier arteries, often combined with locoregional chemotherapy

  • bland embolization

  • transarterial chemoembolisation (TACE)

  • transarterial chemoembolisation with drug-eluting beads (DEB-TACE)

  • hepatic radioembolization (also known as selective internal radiation therapy - SIRT)

• tumor ablation: percutaneous local tumor destruction using a device to cause a focussed zone of cell death

  • thermal ablation techniques

    • radiofrequency ablation (RFA)

    • microwave ablation (MWA)

    • cryoablation

  • non-thermal ablation technique

    • irreversible electroporation (IRE)
