Color Doppler Ultrasound in Portal Hypertension

Abstract

Portal hypertension is one of the most important causes of morbidity and mortality in cirrhotic patients. A color Doppler evaluation of the left gastric vein (LGV) has proven utility in the prediction of esophageal varices and variceal bleeding in patients with portal hypertension. The purpose of this review is to discuss the ultrasound evaluation, imaging findings, and clinical application of Doppler ultrasound in the assessment of the LGV. Knowledge of the color Doppler technique and imaging findings of the LGV may help clinicians improve the monitoring of portal hypertension and predict patients with a high risk of esophageal varices.

Predictive Value of Spectral Computed Tomography Parameters in Esophageal Variceal Rupture and Bleeding in Cirrhosis

“…Hemodynamic changes in the left gastric vein during liver cirrhosis play a crucial role in predicting the risk of EVB. 16 Our results showed that LGVI in the EVB group was higher than that in the non-EVB group, and the risk of EVB would increase when the left gastric venous blood flow increased.…”

The clinical value of color ultrasound screening for fetal cardiovascular abnormalities during the second trimester: A systematic review and meta-analysis

“…[10] It offers several advantages, including minimal trauma, no radiation exposure, quick and convenient operation, and widespread utilization in clinical practice. [11] It can be used for examination of the brain, [12] liver, [13] spleen, [14] stomach, [15] kidney, [16] breast [17] and uterus, [18] along with screening for vascular diseases, especially cardiovascular diseases. [19] Color Doppler can be conveniently and accurately applied in the screening of fetal heart malformations during pregnancy, which can clearly diagnose and reduce the birth rate of newborns with congenital heart disease.…”
