Hemodynamic analysis of esophageal varices in patients with liver cirrhosis using color Doppler ultrasound

Table 1 Hemodynamics in cirrhotic and healthy groups (mean±SD)

Group	Diameter (cm)		Velocity (cm/s)
	PV	LGV	PV	LGV
Controls	1.12±0.11	0.40±0.18	15.3±1.41	8.70±1.91
EVB (–)	1.48±0.15b	0.52±0.21ab	13.7±1.54b	14.8±1.11ab
EVB (+)	1.56±0.28b	0.71±0.34b	12.8±1.18b	16.6±2.62b

EVB, esophageal variceal bleeding; PV, portal vein; LGV, left gastric vein.

^aP<0.05 compared with EVB (+);

^bP<0.01 compared with the healthy controls.
