[End-to-side anastomosis of the carotid artery of the rat with a modified suture technique. Scanning electron microscopy study].

On the basis of a grid-electromicroscopic examination the endothelialisation of the carotis in rats after an end-to-side anastomosis with a non-three-layer individual suture or a continuous three-layer suture is represented. The wall of the non-three-layer suture anastomosis will form an endothelium more quickly and does not seem to include any disadvantages with respect to the function of the anastomosis. The threads of the continuous three-layer suture visible in the interior of the vessels are only covered by the endothelium on the seventh day. The new suturing technique developed by Tulleken et al. will probably not obtain any importance for the IEA bypass and only be employed in individual cases.
