A new animal model of continuous catheterization for investigating mechanisms of arteritis associated with chemotherapy.

Although superselective continuous intra-arterial infusion has advantages for cancer therapy, intra-arterial chemotherapy is often interrupted by arterial damage due to arteritis. Therefore, an animal model must be developed to elucidate the mechanism of arteritis associated with continuous anti-cancer drug infusion. We developed a new rat model with which to investigate the causal mechanism(s) of vascular damage associated with continuous catheterization chemotherapy.
