[ XXXX evaluated by Doppler hepatic vein flow patterns].

@entity1 @entity997 @entity955
Hepatic vein flow can be reliably measured because Doppler sampling volumes are easily oriented parallel with the course of the hepatic vein. In this study, the relationship between the Doppler signal in the hepatic vein and the external jugular vein pulse was evaluated, and the contribution of the Doppler echocardiography to the quantitative diagnosis of @entity997 was also assessed. The subjects consisted of five healthy @entity1 , four @entity1 with lone @entity955 , 27 @entity1 who underwent cardiac surgery, and 34 @entity1 with @entity997 . The severity of the regurgitation was judged by right ventriculography and inferior caval angiography. The pattern of the Doppler hepatic vein flow mimicked that of the jugular phlebogram in each @entity1 . The normal hepatic vein flow consisted of two forward flows toward the heart; one in systole; the other, in diastole, and one retrograde flow toward the liver during atrial contraction. In @entity1 with lone @entity955 , a systolic backward flow toward the liver or a decrease in the systolic forward flow was observed, though there was no @entity997 . In @entity1 who had cardiac surgery, a systolic backward flow toward the liver or a decrease in the systolic forward flow was usual. However, a prominent systolic backward flow toward the liver was observed in @entity1 with severe @entity997 , and a decreased systolic forward flow toward the heart was observed in @entity1 with moderate @entity997 in sinus rhythm. We concluded that Doppler measurement of hepatic vein flow does not contribute to the diagnosis of @entity997 in the presence of @entity955 or in postoperative conditions, but that it is useful in identifying severe @entity997 .
