Vascular corrosion casting uses resin to capture the 3D structure of blood vessels within human and animal tissue.
It is widely used in research as a technique for obtaining the volume and surface area of the blood vessel network within an organ.
[3] Subsequently, the blood vessels of interest are filled with resin (or alternative solidifying material).
The resin is allowed to cure resulting in the blood vessel network containing a solid plastic material.
Surrounding tissue is dissolved away using a corrosive chemical, commonly potassium hydroxide.
