Komatsu, T., Ohta, H., Motegi, H. et al. 2021. A novel model of ischemia in rats with middle cerebral artery occlusion using a microcatheter and zirconia ball under fluoroscopy. Scientific Reports 11(1), 12806.

Here, we present a highly selective rat MCAO model by percutaneous caudal arterial puncture using a microcatheter and zirconia ball under fluoroscopic guidance. The model is predictable and reproducible, which is well confined within the territory supplied by the MCA, and the surgical procedures can be typically completed within 10 min. Furthermore, minimally invasive and highly reproducible procedure lead to a “reduction” in the suffering and “refinement” of the welfare of laboratory animals.
