Tissue Elimination of Large Vascular Corrosion Casting for Anatomy Education

Objective: Vascular corrosion casting is crucial tool for three-dimensional study. Focusing on the gross anatomy, large fatty tissue reacts with corrosive agents resulting in extensive saponification. Our study aimed to prevent saponification by a) finding optimal temperature and concentration of agent b) comparing flow conventional “non-flow” setting.
 Materials Methods: Phase I: pig tissues, weighing 10 g each, were immersed still (non-flowing) solution containing 0.5%, 1%, 5% sodium hydroxide. Different temperatures set find minimum soap-free each concentration. Phases II, III: 6 hearts injected via coronary arteries polymethyl methacrylate. Three non-flowing NaOH solution, while another three placed a flowing solution. The was vertical upward fashion specialized chamber outflow residue collected from system. at temperature. durations compared.
 Results: concentrations 55°C, 54°C, 47°C, respectively. times 216 h, 114 24 Flowing reduced time 25%-39% compared non-flowing.
 Conclusion: most efficient condition minimal 47°C.
