Transjugular intrahepatic portosystemic shunt
Updates to Article Attributes
Body
was changed:
A transjugular intrahepatic portosystemic shunt (TIPS) is a treatment for portal hypertension in which a direct communication is formed between a hepatic vein and a branch of the portal vein, thus bypassing the liver. A successful endpoint is a portosystemic gradient of <12 mmHg.
Indications
Many patients have end stage liver disease. Indications include
- variceal bleeding (preventative in recurrent cases)
- variceal bleeding (for treatment in acute setting5)
- refractory ascites, hepatic hydrothorax
- portal
hypertensivehypertensive gastropathy - hepatorenal syndrome
- lower gastrointestinal and stomal varices
- malignant compression of hepatic or portal veins
- Budd-Chiari syndrome
Relative contraindications
- severeright heart failure
- cavernous transformation of the portal vein
- severe rapidly
progressive hepaticprogressive hepatic failure - multi-cystic hepatic disease
- severe hepatic encephalopathy
- main portal vein occlusion
- polycystic kidney disease
- hypervascular hepatic tumour
Complications
- blockage: TIPS occlusion. A portovenogram with re-stenting is indicated when there is recurrent bleeding and decreased doppler flow on follow up.
- uncontrollable hepatic encephalopathy
- hepatic venous stenosis
- haemorrhage (haemoperitoneum, intrahepatic haematoma, subcapsular haematoma
- sepsis secondary to infection 6
- unintentional arterial access 7,8
Methods to assess patency
- colour Doppler1
- CT angiography 4
- portography with portal manometry
See: TIPS evaluation
Factors affecting poor survival 5
- hyponatremia
- hyperbilirubinemia
- elevated serum ALT
- advanced liver disease
- coexisting renal insufficiency
