摘要:

为探索不同生殖时期母犬生殖系统的超声声像图变化特征,以8只标准试验比格犬为对象,利用彩色多普勒超声诊断仪,在二维灰阶、彩色多普勒超声模式下分别对子宫、卵巢、胎儿进行实时跟踪监测,将获取的声像图进行总结分析,同时对母犬在不同时期进行阴道涂片镜检。结果表明,超声条件下可见发情期母犬卵巢、子宫体积明显逐渐增大,边界清晰,单个卵泡成像明显,子宫腔内可见呈“细线”状的子宫乳,妊娠后23 d超声即可探查到孕囊;彩色多普勒超声下,发情期卵巢内血流明显丰富,后腔静脉和腹主动脉分出的卵巢动静脉相互缠绕,呈红蓝条带相互交织状态进入卵巢;妊娠后子宫血流逐渐丰富,血管内径及血流信号强度迅速增大。超声条件下可实时监测卵巢、子宫及胚胎在不同时期的大小、血流分布变化及其声像图规律,为母犬生殖系统发育过程多普勒超声声像图研究及临床检查提供相应参考依据。

Abstract:

The aim of the present study was to explore the ultrasound image features of pregnant bitches of the reproductive system at different times.In our study,8 standard test Beagles are selected,and the color Doppler instrument was used.The uterus,ovaries and fetus were observed by real-time tracking and monitoring under the two-dimensional gray-scale and color Doppler ultrasound mode.The ultrasound images we got were summarized and analyzed,meanwhile the bitches testing by vaginal smear microscopy.The result of ultrasound image showed that the ovaries and uterus’s volume increased significantly,the line was clear,the follicle was obviously,and the womb milk like ‘thin’ in uterine cavity was visible during the heat period.We tested the fetus at the 23 d of gestation by ultrasound.The blood stream of ovaries was obviously and plentiful,the arteriovenous fistula of ovary from the back cavity vein and the abdominal aorta twisted together as red and blue strap interlace,and flow into the ovary during the estrus by color Doppler ultrasound machine;the blood of uterine was more plentiful gradually after pregnancy,internal diameter and signal intensity of blood vessel rising quickly.The size,blood stream distribution can change during physiology period,and real-time monitored regular pattern of ultrasound image of the ovary,uterus and embryo by ultrasound will provide reference information for bitches reproductive system development and clinical examination.
