Chronic cerebrospinal venous insufficiency (CCSVI) is a syndrome recently described in multiple sclerosis patients. It is characterized by abnormal venous hemodynamics resulting from numerous obstacles in the main veins draining the central nervous system, usually: the internal jugular veins and the azygous vein. Internal jugular vein is the most commonly vein affected. Most of the abnormalities in this vein are located at the level of jugular valve. The aim of this review is to give venographic and schematic descriptions of the most common valvular and perivalvular anomalies found in the lower part of internal jugular vein.
慢性脑脊髓静脉功能不全（CCSVI）是一种最近在多发性硬化症患者中被描述的综合征。其特征是由于引流中枢神经系统的主要静脉（通常是颈内静脉和奇静脉）存在众多障碍而导致的异常静脉血流动力学。颈内静脉是最常受影响的静脉。该静脉的大多数异常位于颈静脉瓣水平。本综述的目的是对颈内静脉下部最常见的瓣膜及瓣膜周围异常进行静脉造影和示意图描述。
