The Jepson classification of Raynaud phenomenon, based on its pathogenesis, is presented. Raynaud phenomenon can be induced in the fingers of the normal hand as the digital vessels are sensitive to the direct effects of cold. A 'local fault' in the digital arteries renders the fingers more susceptible to a fall of environmental temperature, as do limb artery occlusions which impair the digits' ability to maintain their temperature. Other vasoconstrictive influences act similarly to precipitate the onset of the phenomenon.
本文介绍了基于发病机制的雷诺现象的杰普森分类。由于指动脉对寒冷的直接影响敏感，正常手部的手指可诱发雷诺现象。指动脉的“局部缺陷”使手指更容易受到环境温度下降的影响，肢体动脉闭塞也会损害手指维持体温的能力，从而产生类似影响。其他血管收缩因素也会以类似方式促使该现象发作。
