Doppler
sonography was performed in a 1.5 year old healthy German shepherd bitch at
late pregnancy and puerperium stage. Maternal and fetal arteries were
examined by color Doppler and pulsed-wave Doppler ultrasonography. In the
last two weeks of pregnancy, pulsatility and the resistance index were
decreased in vessels. None fetal stress symptoms were observed during
Doppler examinations. Parturition was in the 65th day
spontaneously and six healthy puppies were born. After parturition,
pulsatility and the resistance index was also recorded from artery from
the uteroplacental site. While decreasing of the uterine thickness, there
was a mathematically increase in pulsatility and resistance during the
first thirteen days. It seemed that the Doppler sonography was an
important diagnostic method to evaluate prenatal growth and fetal stress in
this case. Besides this, the Doppler ultrasonography can be used to study
the characteristics of pregnant uterine vessels flow and their
progressive changes during puerperium in the bitch.
