Abstract

The present study was undertaken to assess the technical feasibility of transfemoral hepatic artery catheterization in rats and to describe the imaging techniques that can be used on tumors in rats. A total of 106 N1-S1 cells were inoculated into the left lobes of 74 rats. In 17, transfemoral angiography was attempted. Tumor volumes for 2 weeks before angiography were measured with magnetic resonance imaging in 40 animals. Tumors grew in 63 animals. Angiography was successful in 16 rats. Mean tumor volumes were 0.13 mL and 0.9 mL after 1 and 2 weeks, respectively. In conclusion, transfemoral hepatic artery catheterization is feasible in this animal model.
