Nonsuture microvascular anastomosis using magnet rings: preliminary report.

An original method of nonsuture microvascular anastomosis was developed using magnet rings and hollow cogwheel-shaped metal devices held together by magnetic power. Only 8.3 minutes was required on average for the anastomosis with a high rate of patency. Histologically, a continuity of vascular wall is noted. This method of simple, rapid and reliable microvascular anastomosis appears to be the best one at present.
