Combined vascular‐bronchoalveolar casting using formalin‐fixed canine lungs and a low viscosity silicone rubber

Background: Previous work using unfixed or fixed tissues has shown that casts can be made that demonstrate the three‐dimensional structure of tissues such as the bronchoalveolar tree or the vasculature. In this report, a new method for creating a vascular‐bronchoalveolar cast is described.
