The end-to-end anastomosis of vessels with a diameter of 1 mm or less is an extremely difficult technique (Jacobson et al. 1960; 1962; Yaşargil 1967; Piza-Katzer 1974). It requires thorough training. The common carotid artery of the rat is best suited for this purpose. In regard to its size and consistency, this vessel is comparable to those used in extra-intracranial anastomosis. Mpreover, the changes caused by aging and by chronic hypertension produce morphological changes similar to those that take place in human vessels of the same diameter (Meyermann and Kletter 1977; Meyermann et al. 1977). Another advantage is that rats present no particular difficulties either as test animals or during the operation in comparison with other small experimental animals such as hares and cats. End-to-end microvascular anastomoses are performed on the arteries of hares, ears, however, mainly to practice plastic and reconstructive surgery (Buncke and Schultz 1965).
