1. TIPS - anastomose portossistêmica intra-hepática transjugular. Revisão
Diversas alternativas terapêuticas têm sido usadas, atualmente, na tentativa de reduzir a mortalidade de pacientes com hipertensão portal que desenvolvem varizes esofagianas. Abordagem de uma dessas alternativas que ainda é de exceção e pouco utilizada em nosso meio - o "shunt" (desvio) portossistêmico intra-hepático transjugular - TIPS ("transjugula

2. Differential effects on portal and effective hepatic blood flow. A comparison between transjugular intrahepatic portasystemic shunt and small-diameter H-graft portacaval shunt.
OBJECTIVE: This study was undertaken to determine the effects of transjugular intrahepatic portasystemic shunt (TIPS) and small-diameter prosthetic H-graft portacaval shunt (HGPCS) on portal and effective hepatic blood flow. SUMMARY BACKGROUND DATA: Mortality after TIPS is higher than after HGPCS for bleeding varices. This higher mortality is because of hepa

3. Prognostic factors in survival after portasystemic shunts. Multivariate analysis.
Multivariate analyses correlated short-term survival and long-term survival with clinical data from 141 patients with portasystemic shunts for bleeding esophageal varices over the 8 years from 1974 through 1981. By logistic regression analysis, the elements with independent prognostic significance for operative death were an emergency operation, serum albumi

4. A prospective trial of transjugular intrahepatic portasystemic stent shunts versus small-diameter prosthetic H-graft portacaval shunts in the treatment of bleeding varices.
OBJECTIVE: The authors compare transjugular intrahepatic portasystemic stent shunts (TIPS) to small-diameter prosthetic H-graft portacaval shunts (HGPCS). SUMMARY BACKGROUND DATA: Transjugular intrahepatic portasystemic stent shunts have been embraced as a first-line therapy in the treatment of bleeding varices due to portal hypertension, although they have

5. Hepatic and renal metabolism before and after portasystemic shunts in patients with cirrhosis.
Hepatic cirrhosis with portal hypertension and gastroesophageal hemorrhage is a disease complex that continues to be treated by surgical portasystemic shunts. Whether or not a reduction or diversion of portal blood flow to the liver adversely affects the ability of the liver to maintain fuel homeostasis via gluconeogenesis, glycogenolysis, and ketogenesis is
