Doppler study of hepatic vein in cirrhotic patients: Correlation with liver dysfunction and hepatic hemodynamics

Table 1 Hepatic vein waveforms in study population n (%)

	Non-cirrhotic controls		Liver cirrhosis patients
	No liver	Chronic	A	B	C
	pathology	hepatitis	n = 46	n = 29	n = 25
Triphasic	30	30	26 (56.6%)	16 (55.2%)	7 (28%)
Biphasic	0	0	18 (39.1%)	13 (44.8%)	17 (68%)
