Chronic venous insufficiency of the lower limbs is a frequent disorder that has costly repercussions for society as a whole. It is important to distinguish between abnormality of venous function and its most frequent causes, which are sequelae of deep venous thrombosis and varices of the lower limbs. Chronic venous insufficiency manifests by functional symptoms, based on the heavy leg syndrome, which is very frequent but not specific, and on objective distal signs that are highly specific. Both prognosis and cost of the disorder are based on such objective signs, cutaneous and subcutaneous complications of stasis and of venous hypertension, ranging from simple ochre dermatitis to recurring ulcers and ankylosis of the ankle. Dermo- and hypodermatitis and ulcers complicate less than 10% of chronic venous insufficiency but are responsible for most of the cost involved, two-thirds of which is linked to invalidity. Clinical grades of chronic venous insufficiency have been established, which should facilitate standardisation and comparison of epidemiological, pathophysiological and therapeutic data. Diagnosis of chronic venous insufficiency is by clinical examination, while etiological investigation should most often be done by technical investigation.
下肢慢性静脉功能不全是一种常见疾病，对整个社会造成了高昂的影响。区分静脉功能异常及其最常见病因非常重要，其病因是深静脉血栓形成的后遗症和下肢静脉曲张。慢性静脉功能不全表现为功能性症状，基于非常常见但不具特异性的腿部沉重综合征，以及具有高度特异性的客观远端体征。该疾病的预后和成本均基于此类客观体征、淤滞和静脉高压的皮肤及皮下并发症，范围从单纯的赭色皮炎到复发性溃疡和踝关节强直。皮肤和皮下皮炎及溃疡在不到10%的慢性静脉功能不全病例中出现并发症，但却占了大部分相关成本，其中三分之二与残疾有关。已经确立了慢性静脉功能不全的临床分级，这应有助于流行病学、病理生理学和治疗数据的标准化和比较。慢性静脉功能不全的诊断依靠临床检查，而病因调查通常应通过技术检查进行。
