Abstract: Objective To carry out the training of vascular anastomosis under the microscope in postgraduate students of department of neurosurgery. Methods After the postgraduates carried out the basic operation of the microscope, then they were trained to perform the common carotid artery end to side anastomosis of the rats. Results All the 20 Sprague-Dawley rats who were underwent this procedure survived the operation. The success rate was up to 100%. The anastomoses were almost 100% patent immediately and 1 months after the procedure. HE staining showed good anastomotic healing,without stenosis and false aneurysm. Conclusion Through establishing the a rat model of end to side anastomosis of the carotid artery and special training, the standardization of the operation and a good foundation of applying its skills were developed.
