%X The silicone rubber injection technique was first described in 1999 and has been used in the vascular study of neurology and head and neck dissection. Silicone rubber is durable, flexible, and inexpensive. However, the original silicone rubber injection formula perfuses poorly into the pelvis and extremities. We present a simple modification to the silicone rubber injection technique, showcasing its effectiveness in studying the vascular structures in the pelvis and extremities. We used an ordinary mold-making silicone rubber. The new formula involves mixing the silicone rubber with silicone thinner, acetone, catalyst, and resin color. The mixture is then injected into the artery until the color becomes visible under the skin. The specimen is left at room temperature for 0.5-1 h for the silicone rubber to harden. With our technique, the silicone rubber substance perfuses adequately into small arterial perforators and can penetrate into the subdermal plexus. The smallest subdermal arteries identified under a light microscope measured 6 μm. The modified silicone rubber injection technique has proven to be a valuable tool in anatomical education and surgical training.
