Flowmetry-based portal inflow manipulation for a small-for-size liver graft in a recipient with spontaneous splenorenal shunt

We report a case of living donor liver transplantation using a small-for-size graft (SFSG) with graft to estimated standard liver volume of only 28% in a recipient with spontaneous splenorenal shunt and demonstrate the value of intraoperative ultrasonic flowmetry. Despite an SFSG, the graft was underperfused. This was recognized by flowmetry and was rectified by ligation of the splenorenal shunt.
