[Microsurgical Technique in Injuries of Pheripheral Nerves Part II: Experimental Study (Comparison of Microsuture with the Technique of Gluing by Means of Plasma Coagulum of the Ischiadic Nerve).].
In a group of 20 rabbits the authors compared regeneration of the nervus ischiadicus after microsuture and after gluing the severed nerve with plasma coagulum. In 10 rabbits of group A epineural suture was performed, in 10 rabbits of group B the severed nerve was glued with autologous plasma coagulum. During a three-month regeneration period the authors examined the threshold of sensation 90 days after surgery the anastomosis was examined and also the rate of conduction across the anastomosis. Firmness of the suture was proved in 100% (group A), in two glued nerves dehiscence of the anastomosis occurred, the coagulum was found to be firm in 80 % (group B). When the repaired nerves of both groups were examined, no significant difference was found during clinical examination nor in the conduction across the anastomosis. The method of gluing the nerve with plasma coagulum does not ensure sufficient firmness of the anastomosis on traction. As compared with suture, gluing and preparation of centrifuged plasma is a more tedious method. The method of choice for joining a nerve on the extremities remains microsuture with maximal efforts to achieve adaptation of the corresponding nerve fascicles. Key words: rabbit, nervus ischiadicus, regeneration, microsuture, fibrin coagulum.
