During live ultrasound exploration, individual organs may be difficult to distinguish due to their small volume, high mobility, or small density differences with surrounding tissues and organs. However, their significance in diagnosis and monitoring is significant. If the ovary has a small volume and is surrounded by a fat layer, it is difficult to distinguish it from the surrounding tissue without the development of larger follicles; The uterus is small and its position is uncertain when empty, making it difficult to distinguish. Especially when the cervix opening is used for uterine intubation flushing, it must be located and can be performed under the guidance of animal B-ultrasound, so its position needs to be found accurately. To accumulate experience and verify the accuracy of live exploration ultrasound images, after general anesthesia is applied to animals, surgical incision of the abdominal wall is performed, and rectal exploration is performed under direct visualization with intubation and contrast imaging. The ultrasound images determined during surgery are compared with the preoperative live exploration ultrasound images.

Application of veterinary B-ultrasound in cervical and vaginal catheterization imaging: To verify the position of the cervix and its opening, a rubber catheter is first inserted into the vagina, and at the same time, rectal veterinary B-ultrasound exploration is performed. At the position of the second section, the urinary catheter can be seen twitching, confirming the sonographic features of the vaginal vault. But it was difficult to find the cervix with vaginal catheterization, so a small incision was made from one side of the uterine horn and inserted

Insert another catheter, and when * * * reaches the cervical opening on the ultrasound image, inject a small amount of hydrogen peroxide through the catheter for contrast imaging, forming a strong echo light mass at the cervix to verify the position of the cervical opening.

Application of Veterinary Ultrasound in hydrogen peroxide contrast surgery for uterine horns: The empty uterus is a solid dark area in front of the bladder during live exploration, but it is difficult to distinguish the uterine horns. To confirm the position of the uterine horn, a small amount of hydrogen peroxide is injected into one side of the uterine horn during the operation. The gas generated by the hydrogen peroxide fills the uterine horn and forms a regular strong echo light cluster. Confirm that the solid dark area observed before surgery is indeed the uterine echo area.

Application of veterinary B-ultrasound in ovarian localization surgery: The ovary is a solid organ surrounded by a serosal layer and mostly covered with a thin layer of fat. During live exploration, it appears as an oval solid dark area structure with peripheral echoes, which are slightly stronger than uterine echoes. When there is follicular development, small circular liquid dark areas can be seen, but without follicular development, it is difficult to distinguish them from the transverse section of the uterine horn. Therefore, during the surgery, the ovary is pulled near the incision, fixed behind it with fingers, and filled with physiological saline solution inside the incision, followed by rectal exploration. Clearly visible ovarian structure and finger echoes with acoustic shadows behind the ovaries, consistent with live exploration ultrasound images.
