Corrosion Cast of Bronchopulmonary Segments

Department of Anatomy Sapthagiri Institute of Medical Sciences and Research Center Chikkasandra, Hesaragatta Main Road Bengaluru560090 Karnataka, India ABSTRACT: The tracheo-bronchial tree is rather difficult for anyone to understand without visual aids. Luminal corrosion casts made of silicone sealant material give a better orientation that aids understanding. Many different materials like gelatin and different types of silicone, and different methods such as injecting the solutions with a syringe and a gun have previously been used in cast preparation. Some methods are costly, and some are difficult to carry out, requiring much care in the procedures. In the present study, the sealant material “WACKER GP” general purpose silicone sealant, (Wacker® Wacker Chemie AG Munich, Germany), which is low in cost and easily available in hardware shops, has been used. The method adopted to inject the silicone using an injection gun is relatively very easy. The prepared bronchial tree cast was found to be safe to handle, soft, flexible and has long-lasting durability. The cost of preparation is very low compared to other methods.
