title: Animal models for therapeutic embolization.
abstract: Embolization techniques have been performed in different animals to accumulate basic data before a clinical trial. Choosing the right embolization model for a specific project is critical. However, there are several variables when defining the best model for embolization research such as the size of the animal to be used, the target organs, the route of introducing the embolization agent, and the feasible methods of evaluation. Commonly used research animals for endovascular embolization include rabbits, dogs, and rats. Frequently used target organs are the kidney and the liver. Most models use a transcatheter for introducing the embolus and occasionally open surgery and direct arterial injection are used. Basic methods of evaluation are straightforward, and commonly include macro observation of the embolized organs, angiogram, and histology. This article concisely reviews the available animal models and their evaluation for embolization research to help researchers to choose the appropriate model.
