Abstract

Microvascular anastomosis has become a general and essential technique in the field of vascular reconstructive surgery. Side-to-side microvascular anastomosis is rarely performed by microsurgeons. Laboratory training models are essential for the development and refinement of microsurgical techniques. A new experimental model of a side-to-side "arterial" anastomosis in the rat internal and external carotid arteries is presented, in which 100 percent patency was accomplished immediately, and was maintained 7 days after anastomosis. This model can provide an experimental and training tool for side-to-side anastomosis of small arteries.
