Resumo

CONTEXTO: A insuficiência venosa crônica dos membros inferiores é a mais prevalente das doenças venosas. Muito se discute sobre sua etiologia e fisiopatologia. Vários fatores de risco têm sido associados ao seu desenvolvimento, como idade, sexo, dieta, entre outros. A obesidade é um problema de saúde pública e sua incidência tem aumentado. O ecocolor Doppler é um método útil para avaliar a presença de refluxo e/ou obstrução no sistema venoso. OBJETIVO: Comparar a prevalência de insuficiência venosa superficial e sintomas associados em pacientes obesos e não obesos. MÉTODOS: Após pesagem, medição da estatura e exame físico, os pacientes com índice de massa corpórea (IMC) <30 kg/m² e >35 kg/m² e queixas compatíveis com insuficiência venosa foram distribuídos nos grupos I e II, respectivamente. Foram submetidos à realização do ecocolor Doppler dos membros inferiores para avaliação da presença ou não de refluxo. RESULTADOS: Foram examinados 311 membros de 168 pacientes com 25-72 anos. Para análise estatística, foram consideradas queixas de varizes, dor, edema, dermatite, eczema e úlcera, associados ou não. Foi obtido um total de 109 e 104 membros com varizes nos grupos I e II, respectivamente. Queixas de varizes visíveis (p<0,001) e varizes visíveis com dor (p = 0,0118) foram mais prevalentes no grupo I. Queixas de varizes com edema (p<0,001), somente edema (p<0,001) e edema associado a dor (p<0,001) foram mais prevalentes no grupo II. Os dados não mostraram diferença estatisticamente significante na prevalência de varizes entre os grupos I e II. CONCLUSÃO: A prevalência de varizes é semelhante entre os obesos e não obesos; as queixas clínicas diferem entre os grupos e são compatíveis e dependentes da presença de insuficiência venosa.

Abstract

BACKGROUND: Chronic venous insufficiency of the lower limbs is the most prevalent venous disease. There is an ongoing debate about its etiology and pathophysiology. Several risk factors have been associated with its development, such as age, sex and diet. Obesity is a public health problem and its prevalence has been increasing. Color Doppler ultrasonography is a useful method to evaluate the presence of reflux and/or obstruction of the venous system. OBJECTIVE: To compare the prevalence of superficial venous insufficiency and associated symptoms in obese and non-obese patients. METHODS: After weighing, height measurement and physical examination, patients with body mass index (BMI) <30 kg/m² and >35 kg/m² and complaints compatible with venous insufficiency were divided into groups I and II, respectively. They underwent color Doppler ultrasonography of the lower limbs, in order to assess the presence or absence of reflux. RESULTS: A total of 311 limbs of 168 patients 25 to 72 years old were examined. For statistical analysis, complaints of varicose veins, pain, swelling, dermatitis, eczema and ulcers, associated or not, were considered. A total of 109 and 104 limbs with varicose veins were obtained in groups I and II, respectively. The prevalence of visible varicose veins (p<0.001) and visible varicose veins with pain (p=0.0118) was higher in group I. Complaints of varicose veins with edema (p<0.001), only edema (p<0.001) and edema with pain (p<0.001) were more prevalent in group II. Data did not present significant statistical difference in the prevalence of varicose veins between groups I and II. CONCLUSION: The prevalence of varicose veins in obese and non-obese individuals is similar ; clinical complaints differ between groups and are consistent and dependent on the presence of venous insufficiency.
