Análise de peças anatômicas preservadas com resina de poliester para estudo em anatomia humana

Abstract

Objective: To evaluate the use of polyester resin in preserving anatomical specimens for the study of human anatomy. Methods: We used 150 anatomical specimens, comprised of unfixed (fresh), fixed in 10% formalin and vascular casts of organs injected with vinyl acetate and polyester resin. The solution used consisted of polyester resin with the diluent styrene monomer and catalyst (peroxol). After embedding in this solution, models in transparent resin were obtained, allowing full observation of structures and conservation of the specimens used. Results: upon evaluation of the specimens, we observed a high degree of transparency, which promoted a complete visualization of structures with perfect preservation of the anatomy. The average time for the completion of the embedding was 48 hours. Only 14 specimens (9.3%) were lost during the preparation. Conclusion: Polyester resin can be used for preserving anatomical specimens for teaching human anatomy in a practical, aesthetic and durable way.
