[Hemodynamic study of distal splenorenal shunt (DSRS)]

Color-flow Doppler sonography (FDS) was used for assessing the hemodynamic changes in 8 patients undergoing distal splenorenal shunt (DSRS). Results were compared with 14 patients with portal-azygos disconnection (PAD). It was found that 3 weeks after DSRS portal venous flow (PVF) decreased by 50%, and at least in some patients the reduction of the PVF was a continuous process during the period of two years in the DSRS group. The postoperative decrease in PVF in DSRS patients was in sharp contrast to that in PAD patients (P < 0.001), hence PAD is superior to DSRS in remaining satisfactory PVF.
