Protocol for renal artery embolization via caudal artery in rats

Transvascular embolic materials are vital for acute hemorrhages and tumors, but newly developed materials require preclinical validation. Here, we present a protocol for renal artery embolization through the caudal artery of rats. We describe steps for rat anesthesia, heparinization of surgical materials, and isolation of the rat caudal artery. We then detail procedures for puncturing and intubating the rat caudal artery and superselective renal artery embolization.
