Venous Doppler in the Evaluation of Fetal Hydrops

Table 2

Relationship between cause of hydrops and mortality and abnormal venous blood velocity.

	Number	Mortality	Mortality minus termination	Abnormal HV PIV	Abnormal DV PIV	UV pulsations
Number		51	32	39	34	49
High-output heart failure	32	9 (28%)	7 (23%)	11 (34%)	8 (25%)	13 (41%)
Low-output heart failure	24	19 (79%)	10 (67%)	15 (63%)∗	18 (75%)∗	18 (75%)∗
Venous obstruction	25	10 (40%)	7 (32%)	7 (28%)	5 (20%)	8 (32%)
Idiopathic	19	13 (68%)	8 (57%)	6 (32%)	3 (16%)	10 (53%)

DV: ductus venosus; HV: right hepatic vein;
PIVs: pulsatility index for veins; UV: umbilical venous.
Abnormal PIV was defined as > 95th percentile.
