Transjugular Intrahepatic Portosystemic Shunt (TIPSS) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Summary of Trials Comparing TIPSS to Endoscopic Therapy for Variceal Bleeding Stanley. Lancet. 1997;350(9086):1235-1239. Generally, higher rates of rebleeding were more common after  Endoscopy treatment, while encephalopathy rates were higher in the  TIPSS groups
Complications of TIPSS ,[object Object],[object Object],[object Object],[object Object],[object Object]
Conditions Which May Contraindicate TIPSS This venogram shows an occlusive thrombus of the portal vein, which may make safe TIPSS placement impossible.   This abdominal CT demonstrates a large hypodense hepatic lesion due to  hepatocellular carcinoma in a very  shrunken cirrhotic liver. Other contraindications include hepatic vein occlusion, heart failure or pulmonary hypertension, biliary obstruction, and poorly controlled systemic infection.
TIPSS Thrombosis/Stenosis ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Trans-TIPSS Embolization of Persistent Varices Persistent variceal bleeding due to high flow collaterals despite a patent TIPS shunt may be coil-embolized radiologically via the TIPS shunt itself.
Acute Variceal Hemorrhage: Surgery ,[object Object],[object Object],[object Object],[object Object]
Relative Effectiveness of  Available Therapies for  the Prevention of Recurrent Variceal Bleeding Beta-blockers are the single most effective and safest strategy to prevent the recurrence of variceal  Bleeding.  More aggressive strategies such as banding, TIPSS, or  shunt surgery may decrease bleeding but are associated with higher risks and costs. Sharara A, et al. N Engl J Med. 2001.

  • 22. Summary of Trials Comparing TIPSS to Endoscopic Therapy for Variceal Bleeding Stanley. Lancet. 1997;350(9086):1235-1239. Generally, higher rates of rebleeding were more common after Endoscopy treatment, while encephalopathy rates were higher in the TIPSS groups
  • 23.
  • 24. Conditions Which May Contraindicate TIPSS This venogram shows an occlusive thrombus of the portal vein, which may make safe TIPSS placement impossible. This abdominal CT demonstrates a large hypodense hepatic lesion due to hepatocellular carcinoma in a very shrunken cirrhotic liver. Other contraindications include hepatic vein occlusion, heart failure or pulmonary hypertension, biliary obstruction, and poorly controlled systemic infection.

  • 28. Relative Effectiveness of Available Therapies for the Prevention of Recurrent Variceal Bleeding Beta-blockers are the single most effective and safest strategy to prevent the recurrence of variceal Bleeding. More aggressive strategies such as banding, TIPSS, or shunt surgery may decrease bleeding but are associated with higher risks and costs. Sharara A, et al. N Engl J Med. 2001.
