Abstract
In medical terms, cast refers to the replica obtained after filling a luminal structure with resin to reproduce its morphology. It can be accomplished by removing the soft tissue around it, termed corrosion or maceration. Corrosion casts form very important material in learning morphology of various structures like- vascular tree, tracheobronchial tree, luminal casts of various organs. Vascular casts have been studied using scanning electron microscopy, which has contributed to understanding the biological processes. If the specimen is fixed after resin injection, it can be used for surgical training, medical teaching etc. In the present review, the authors have tried to analyse the technical aspects of corrosion casting. We have also added note on polyurethane foam cast of coronary vessels, which was carried out in our laboratory.
Highlights
Casting refers to filling of anatomical or pathological spaces with extraneous material which results in the production of a three-dimensional replica of the said space.[1]

Summary
Casting refers to filling of anatomical or pathological spaces with extraneous material which results in the production of a three-dimensional replica of the said space.[1]. Tompsett (1970) suggested the injection of tissues c) Hard materials: polyesters, epoxy resin, Methyl with 4% formalin prior to casting They stopped perfusion at methacrylate (Mercox), polyurethanes. Least 24 hours before resin injection, to facilitate the escape of excess fluid.[7] Use of hydrogen peroxide (1-2% H2O2) Casting materials and their application in research and has been suggested, to clean the lumen of clots or debris teaching have been exhaustively reviewed by Kati (Important to wash after H2O2, otherwise H2O2 itself may damage the tissue).[3]. The media used for casting vary in physicochemical fixatives used include formaldehyde, glutaraldehyde, and properties- viscosity, replication quality, properties, paraformaldehyde in differing concentrations Describe that the specimens which cannot be processed immediately can be refrigerated and injection can be done
