With the objective of studying the spectrum of clinical manifestations of Chronic Venous Insufficiency (CVI), we conducted an epidemiological survey in 17 of the 20 districts in Portugal. This study involved 436 general practitioners and 8243 consecutive attendants of the national health service aged 15 and over, who were inquired for symptoms and signs of CVI. The diagnosis of CVI was established on clinical grounds by the physicians, who recorded data on demography, associated diseases, past history, symptoms, physical signs, and characteristics and location of varicose veins. These data were combined with the estimates of prevalence of CVI obtained in a previous study on 45,000 individuals and with the results of the population census of 1991 to obtain age and sex adjusted population prevalences of the disease manifestations. The results show that the prevalence of CVI, radicular and troncular varices, and troncular varices is 20, 12 and 6% in males and 40, 22 and 10% in females. The prevalence of grade 0, 1, 2 and 3 CVI is 2, 10, 6 and 3% in males and 4, 22, 12 and 4% in females. The prevalence of a history of phlebitis and venous thrombosis is 4.5 and 1.3% in males and 8.9 and 1.5% in females. The prevalence of chronic venous ulcer, either active and inactive, is 3.2% in males and 3.9% in females. These data indicate that the situation of CVI in Portugal is similar to that reported in other European countries.
为研究慢性静脉功能不全（CVI）的临床表现谱，我们在葡萄牙20个区中的17个区开展了一项流行病学调查。该研究涉及436名全科医生以及8243名年龄在15岁及以上、连续就诊于国家医疗服务机构的患者，对他们进行了CVI症状和体征的询问。医生依据临床情况对CVI进行诊断，并记录了人口统计学、相关疾病、既往史、症状、体征以及静脉曲张的特征和部位等数据。这些数据与之前对45000人进行的一项研究中获得的CVI患病率估计值以及1991年人口普查结果相结合，以得出按年龄和性别调整后的该疾病表现的人群患病率。结果显示，男性中CVI、根部和躯干静脉曲张以及躯干静脉曲张的患病率分别为20%、12%和6%，女性分别为40%、22%和10%。男性中0级、1级、2级和3级CVI的患病率分别为2%、10%、6%和3%，女性分别为4%、22%、12%和4%。男性中静脉炎和静脉血栓形成病史的患病率分别为4.5%和1.3%，女性分别为8.9%和1.5%。无论活动期还是非活动期，慢性静脉溃疡的患病率男性为3.2%，女性为3.9%。这些数据表明，葡萄牙的CVI情况与其他欧洲国家报告的情况相似。
