对牛蹄部动、静脉血管吻合支的观察研究
Observational Study on the Anastomotic Branches of Arterial and Venous Vessels in the Hoof of Cattle
摘要
Abstract
In order to clarify the main reason for the presence of red casting fluid from the arteries into the veins in Cow's hoof blood vessels cast specimens.In this study,three specimens of red and blue coloured arterial and venous vascular casts of bovine hooves were cut into several small slices and observed under the microscope,and it was found that anastomotic branches were observed in many places between small and micro arterial and venous vessels in the dermis of the hooves;X-ray angiography with 76%compound pantethine-glucosamine was performed,and it was clearly observed on the fluoroscopic screen that the contrast agent injected from the third common artery on the lateral side of the fingers and palms passed through the short circuit of the artery and vein near the fork of the third common artery on the lateral side of the fingers and palms 2/3 below the knuckle bone,and entered the veins on the lateral side of the fingers and palms directly.In conclusion,it was shown that the casting fluid used could not enter the vein from the artery through the capillary network,and that the red casting fluid entered the vein from the artery through the open anastomotic branch between the artery and vein in the hoof of the cow or through a short circuit.关键词
