Parâmetros dopplervelocimétricos na avaliação da perviedade da anastomose portossistêmica intra-hepática transjugular (TIPS)

Abstract: A anastomose portossistêmica intra-hepática transjugular (TIPS) é um procedimento intervencionista minimamente invasivo realizado pela introdução de prótese metálica auto-expansível no parênquima hepático, via transjugular. Tem por objetivo tratar as complicações da hipertensão portal, principalmente a hemorragia digestiva alta e a ascite refratária. A estenose é complicação freqüente, embora o procedimento seja eficaz e com baixo índice de insucesso. O diagnóstico precoce da estenose é de fundamental importân… Show more

“…Maybe, the major impact of US is observed in the analysis of the portal circulation, especially after the introduction of the Doppler technology (1) . In the eighties, with the introduction and development of the technique of transjugular intrahepatic portosystemic shunt, the Doppler method emerged as an useful toll for following up patients who have been submitted to this procedure (2,3) , as well as those who have undergone liver transplant (4) . More recent studies start evaluating the usefulness of magnetic resonance imaging in the evaluation of the portal system, hepatic parenchyma and other solid viscera (5,6) .…”
