Abstract:

BACKGROUND: The research on lower extremity vascular disease is becoming popular. In the experiment of large animals as research platform, it is necessary to detect the shape and density of lower extremity vascular in order to study and verify the effectiveness of intervention measures, and this detection method needs high feasibility and repeatability.

OBJECTIVE: To investigate the feasibility, influencing factors and application value of digital subtraction angiography in lower limb arteriography of a canine animal model.

METHODS: Six Beagle dogs were fixed on the working bed after anesthesia and punctured percutaneously through the femoral artery with an indwelling needle. Contrast agent was injected artificially. Digital subtraction angiography bolus chase technology was used to collect contrast images. The image effect and influencing factors were analyzed.

RESULTS AND CONCLUSION: (1) The final arteriography images of all six Beagle dogs’ hind limbs were clear, and the branches of small vessels could be distinguished without artifacts. (2) The first beagle shook when encountering contrast agent stimulation during the initial angiography, resulting in poor image effect. After fixing the limbs and diluting the contrast agent, the clear images were obtained by re-angiography. (3) These results indicate that arteriography using digital subtraction angiography can clearly reveal the shape and density of blood vessels in canine animal models. It is simple and reproducible, and is of great significance for research on animal models of limb ischemia.
