Abstract

PURPOSE

The ductus venosus (DV) blood flow has been studied in fetal lambs and in humans. This study aims to describe the velocities, the Doppler indices and the morphological patterns of the venous blood flow in the DV of canine fetuses during physiological pregnancy.

METHODS

The DV of 55 canine fetuses has been evaluated and the waveforms described using B-mode, color and pulsed-wave Doppler ultrasound technology.

RESULTS

We found 48 diphasic waves and 7 threephasic waves. No monophasic waveform was found. Six of seven threephasic waveforms belonged to litters in which perinatal mortality occurred. The peak velocity during ventricular systole S (cm/s), the peak velocity during the ventricular diastole D (cm/s), the velocity during atrial contraction aV (cm/s), the S/D index, the pulsatility index (PI) and the resistance index were measured.

CONCLUSIONS

All Doppler indices and velocities were significantly correlated with each other (p < 0.05). The number of newborn puppies and the age of bitches were not related to DV vascular indices or flow rate (p > 0.05). Gestational age was proportional to the PI (p < 0.02). Doppler ultrasonography allows the assessment of DV blood flow in canine fetuses during pregnancy.

摘要

目的

已在胎羊和人类中研究了静脉导管（DV）血流。本研究旨在描述生理妊娠期间犬胎儿DV中静脉血流的速度、多普勒指数和形态模式。

方法

对55只犬胎儿的DV进行了评估，并使用B超、彩色和脉冲波多普勒超声技术描述了波形。

结果

我们发现48个双相波和7个三相波。未发现单相波形。七个三相波形中的六个属于围产期发生死亡的窝。测量了心室收缩期峰值速度S（cm/s）、心室舒张期峰值速度D（cm/s）、心房收缩期速度aV（cm/s）、S/D指数、搏动指数（PI）和阻力指数。

结论

所有多普勒指数和速度之间均存在显著相关性（p < 0.05）。新生幼犬数量和母犬年龄与DV血管指数或流速无关（p > 0.05）。孕龄与PI成正比（p < 0.02）。多普勒超声检查可用于评估妊娠期间犬胎儿的DV血流。
