Abstract：
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.
摘要：
硅橡胶注射技术于1999年首次被描述，并已用于神经病学和头颈解剖的血管研究。硅橡胶经久耐用，灵活,而且便宜。然而,原来的硅橡胶注射配方对骨盆和四肢的灌注不良。我们提出了对硅橡胶注射技术的简单改进，展示其在研究骨盆和四肢血管结构方面的有效性。我们用普通的模具制作硅橡胶。新配方涉及将硅橡胶与有机硅稀释剂混合，丙酮,催化剂,和树脂颜色。然后将混合物注射到动脉中，直到颜色在皮肤下可见。将样品在室温下放置0.5-1小时以使硅橡胶硬化。用我们的技术,硅橡胶物质充分灌注到小动脉穿孔器中，并可以渗透到真皮下丛中。在光学显微镜下确定的最小皮下动脉测量为6μm。改良的硅橡胶注射技术已被证明是解剖教育和手术训练中的宝贵工具。
