Summary: | The purpose of this study was to investigate the relationship between a series of portal hemodynamic parameters obtained with Doppler ultrasonography and portal pressure measured directly from patients with portal hypertension (PHT).
Fifty-seven patients with a clinical diagnosis of PHT who accepted surgical therapy were investigated. The portal pressure was measured directly intraoperatively. Relevant parameters were compared and measured, including the hepatic artery pulsatility index (HAPI), hepatic artery resistive index (HARI), splenic artery resistive index, splenic artery pulsatility index (SpAPI), congestion index (CI) of the portal vein, hepatic buffer index (HBI), liver vascular index (LVI), and PHT index (PHI).
Doppler parameters for the postprandial HAPI, SpAPI, CI, LVI, HBI, and PHI were statistically different in patients with PHT and healthy control subjects (P |
