title: Assessment of uterine involution in bitches using B-mode and Doppler ultrasonography.
abstract: The aim of this study was to measure the uterine diameter by B-mode and Doppler velocimetry patterns of uterine arteries in postpartum female dogs after normal delivery or cesarean section (c-section). Ten female dogs were assessed on weeks 0, 1, 2, 3 and 4 postpartum. Only at week 0, bitches submitted to c-section presented higher body diameters and uterine horns when compared to normal delivery. It was observed a reduction in uterine diameters over the weeks in both groups. In general, bitches submitted to c-section presented lower uterine perfusion. Each group presented distinct Doppler velocimetric characteristics. It was concluded that the B-mode ultrasound and Doppler are important tools for assessing puerperal uterine with distinct characteristics influenced by the type of delivery.
