[Practical Bypass Training for Young Neurosurgeons].

Microvascular anastomosis is an essential technique for cerebrovascular surgeons. Practicing microvascular anastomosis in off-the-job training is critical to perform high-quality revascularization surgery. Gauze, silicone tubes, and artificial blood vessels are useful for daily training practice. Anastomosis training using rats, if available, is more effective. This paper presents practical training procedures for novice neurosurgeons, in particular related to microvascular anastomosis, to improve their microsurgical techniques.
