[Color Doppler in evaluating the effects of octreotide on portal hemodynamics]
1Ultrasound Department, Memorial Hospital, Sun Yat-Sen University of Medical Sciences, Guangzhou.
Objective:
To study the effects of octreotide on portal pressure and the relationship between the portal pressure and portal hemodynamics measured by color Doppler.
Methods:
A high portal resistance model by injecting bletilla hyacinthina was established in 6 dogs. The portal pressure and portal hemodynamics studied by color Doppler were measured respectively by two investigators before and after injecting octreotide into the peripheral vein.
Results:
Portal hypertension was caused by injecting bletilla hyacinthina into the portal vein. The portal pressure was reduced and portal venous velocity increased after injecting octreotide into the peripheral vein. There was a significant negative correlation between the portal pressure and portal venous velocity.
Conclusion:
Color Doppler is helpful in evaluating the effects of octreotide on the portal pressure.
