下肢静脉曲张是一种常见疾病,长期站立工作、重体力劳动是该病的诱因。其发病机理是大隐静脉瓣膜处瘤样扩张,使下肢浅静脉与深静脉汇合处的瓣膜失去“单向阀门”的作用,下肢血液向心方向回流障碍,导致静脉血液倒流、大隐静脉淤血,至使静脉扩张。下肢静脉曲张早期表现为下肢浅静脉呈蚯蚓状扩张,站立时患者感到腿部酸胀和疼痛,行走或平卧位时不适感消失。病程进 Varicose veins of the lower extremities is a common disease, long standing work, heavy manual labor is the cause of the disease. Its pathogenesis is the saphenous vein at the tumor-like dilatation, the lower limb veins and deep venous confluence of valves lost “one-way valve” effect, lower extremity blood flow to the heart of the obstacles, leading to venous blood back, hidden Venous congestion, to make the vein dilated. Lower extremity varicose veins showed early earthworm-like dilatation of the lower extremities, standing patients feel sore legs and pain, discomfort disappeared when walking or supine position.
