Abstract
Introduction The technical difficulties involved in the anastomosis of small blood vessels (ie, 3-4 mm) is well known. One group1 has proposed a simple, rapid, nonsuture technique. Others2 have concluded that sutured anastomosis in small vessels is superior to the non-suture technique, even though the latter is more appealing. Utilizing light microscopy and the suture technique, excellent results have been obtained. The present study was undertaken to compare the results of sutured anastomosis with and without the use of light microscopy and to apply this study to very small vessels (ie, 1-2 mm). Since blood flow is frugal in vessels of this caliber, it seemed feasible that a comparison of these two techniques would be a valuable study. Materials and Methods Sixty anastomoses were performed on 11 mongrel dogs. The vein size ranged between 1-2 mm. In all animals biangular simple continuous suture was used. The veins on
