[Suture and gluing technics in microvascular surgery. Comparative animal-experiment clinical studies]

In 135 femoral vessels of rats (70 arteries, 60 veins) end-to-end anastomoses performed, using 3 different methods (anastomoses with interrupted sutures, two-suture telescopic anastomosis, sutureless telescopic anastomosis with fibrinogen adhesive). The advantages and disadvantages of these methods were investigated and valued by clinical aspects (time of anastomosing, patency rate, complications). The results showed that a combined two-suture-telescopic anastomosis using absorbable suture material and fibrinogen adhesive is very stable and causes minimal lesions of the vessel wall, so that this method will be a nearly ideal anastomosing technique.
