A re-appraisal and modification of the Lauritzen technique of microvascular anastomoses.
Twenty arterial anastomoses were performed in ten Sprague-Dawley rats, utilising a modification of the Lauritzen technique which was being re-evaluated because of its apparent simplicity and high patency rate. In 90% of the anastomoses performed patency was confirmed one week after operation. Histological examination at this time revealed neo-endothelialisation across the anastomotic site. It is clear that this technique is a very efficient method of anastomosing vessels of similar size in the experimental animal where tension is not a problem and should be considered for use in suitable cases in man.
