Resin corrosion cast in experimental evaluation of femoral microanastomosis

Abstract

In order to obtain more information about the site of microvascular anastomosis, the authors used the methylmethacrylate resin corrosion casts. 80 microvascular anastomoses were performed in Wistar albino rats and divided into two groups : in the Group 1 (40 anastomoses), the resin was injected into the vessel whereas in Group 2, the tissues were prepared without injecting resin. Both groups were compared under the scanning electron microscope (SEM). The SEM preparation was easier in the Group 1 and the artefacts were significantly reduced. The anastomotic site was better appreciated in Group 1 in three-dimensional views. The resin corrosion cast is a promising technique for the evaluation of the microvascular anastomosis. © 1988 Société d'Édition de l'Association d'Enseignement Médical des Hôpitaux de Paris.
