[Doppler color flow imaging for demonstrating changes in portal hemodynamic after Hassab procedure].

Doppler color flow imaging (DCFI) was used to observe portal hemodynamic changes in 40 patients with portal hypertension after Hassab procedure. Preoperative portal blood flow was hepatopetal in all patients, and in 30 of them gastric coronary vein was shown, with the hepatofugal blood flow of 235.32 +/- 56.24 ml/min, and the velocity of 8.62 +/- 2.33 cm/sec. Postoperatively, the gastric coronary vein was interrupted in 27 patients, the portal blood flow was significantly increased from 742.62 +/- 141.73 ml/min to 986.82 +/- 134.58 ml/min (P < 0.01) and the velocity was increased from 10.14 +/- 2.13 cm/sec to 13.41 +/- 1.91 cm/sec (P < 0.01). The results showed that the operation can stop abnormal blood flow in the gastrosplenic region and enhance liver perfusion. DCFI is useful for postoperative follow-up and observing portal hemodynamic changes.
