Reference range of gestational uterine artery resistance index in small canine breeds

The objectives of this study were to evaluate the uterine artery blood flow during the second half of normal pregnancy in small breed dogs and to determine the RI reference values of this artery in these bitches. Fifty-two, 1.5 –6.5 kg, purebred healthy pregnant bitches were included in this study. Doppler ultrasonographic examinations of the uterus were performed every 10 days from Day 30 of the estrous cycle to parturition. Peak systolic velocity (PSV) and end diastolic velocity (EDV) of the uterine artery were measur ed while RI [(PSV−EDV)/PSV] was automatically calculated.
