Blood flow in the splanchnic veins was studied in cirrhotics and matched controls by means of a system that combines a mechanical sector scanner with a pulsed Doppler. The measurements were validated in an in vitro model. Echo‐doppler studies could be carried out reproducibly in only approximately two‐thirds of cases because of poor echo transmission or incomplete cooperation. Portal blood velocity was significantly reduced in cirrhotics (10.5 ± 0.6 cds versus 16.0 ± 0.5 in controls; p < 0.001), but portal blood flow was normal because of enlarged portal caliber. A complete hemodynamic evaluation of the splenic and superior mesenteric veins was possible in only a few subjects. In selected patients the technique may prove relevant in the study of hemodynamic effects of drugs and surgery on portal blood flow.
