Direct measurement of portal venous blood flow is technically difficult, yet crucial for accurate assessment of liver hemodynamic and metabolic functions. The aim of this investigation was to assess the feasibility of implanting transit-time ultra-sound (TTUS) perivascular flow probes on the portal...
