  • Employed a rabbit carotid artery bifurcation model for aneurysm clipping simulation.

    • Main Results:

    • Surgical duration and suture errors increased with complexity.
    • Anastomosis patency rates decreased as procedural difficulty rose.
    • The animal model provided insights into aneurysm clipping and occlusion.

    Conclusions:

    • PVC rat and PVA vascular models are effective for advanced microvascular anastomosis training.
    • The rabbit carotid artery model enhances expertise in vascular surgery.
    • These models are valuable for practicing aneurysm clipping and occlusion techniques.
