The end-to-side anastomosis is 1 of the most common anastomosis configurations used in cerebrovascular surgery. Although several living practice models have been proposed for this technique, few involve purely arterial vessels. The purpose of the present study was to compare 2 arterial models using common carotid arteries (CCAs) and common iliac arteries (CIAs) in rats. ⋯ Both CCA and CIA models could be efficiently used for practicing the end-to-side anastomosis technique. Each model provides the trainee with a specific set of advantages and disadvantages that could help with the optimal selection of the practice model according to trainee's skill level.
