| 静脉曲张是静脉系统最常见的疾病，形成的主要原因是由于先天性血管壁膜比较薄弱或长时间维持相同姿势很少改变，血液蓄积下肢，在日积月累的情况下破坏静脉瓣膜而产生静脉压过高，是血管突出皮肤表面的症状。静脉曲张最常发生的部位在下肢。值得强调的是，静脉曲张本身可能是其他病变的继发表现，如腔静脉闭塞等，应积极处理原发病。 Varicose veins are the most common diseases of the venous system. The main reason for the formation of varicose veins is that congenital vessel walls are weak or maintain the same posture for a long time with little change. Blood accumulates in the lower limbs and destroys the venous valves in the cumulative situation, resulting in high venous pressure, which is a symptom of the skin surface of vascular protrusion. Varicose veins occur most frequently in the lower extremities. It is worth emphasizing that varicose veins themselves may be a secondary manifestation of other diseases, such as vena cava occlusion, and the primary diseases should be actively dealt with. |
