Usually a single end-to-end anastomosis on a middle-size vessel cannot
be performed in less than twenty minutes with either separate or cont
inuous suture technique. For easy and quick anastomoses the authors st
udied 12 dogs with a sutureless concept, With this method proximal and
distal ends of a vessel were joined by means of a polydioxanone tube
connector. The sutureless procedure took approximately five minutes to
complete, Six months after the operation the anastomoses were examine
d and more than 41% of the vessels were found patent. The authors' opi
nion is that, if polydioxanone tube is prepared more properly the rate
of patency will be higher than this.
