Contexto: A eventual relação entre a aterosclerose das artérias dos membros inferiores com a aterosclerose das artérias intestinais foi pouco estudada. Objetivo: Avaliar pela ecografia vascular (Doppler) presença de lesões com estenose 70% na artéria mesentérica superior e/ou tronco celíaco em doentes com arteriopatia obstrutiva crônica dos membros inferiores. Método: Foram estudados dois grupos, cada um com 60 doentes (40 homens e 20 mulheres). O grupo-caso foi composto por doentes com arteriopatia obstrutiva crônica dos membros inferiores, claudicação intermitente limitante ou dor de repouso e/ou lesões tróficas de extremidade, sem queixas gastrintestinais. O grupo-controle foi constituído por enfermos sem doença arterial obstrutiva dos membros inferiores e sem queixas gastrintestinais. Consideraram-se fatores de risco presença de diabetes melito, hipertensão arterial, obesidade, angina/infarto, tabagismo e dislipidemia. Todos os doentes foram submetidos a ecografia vascular do tronco celíaco e da artéria mesentérica superior. Os doentes do grupo-caso foram separados pela presença de claudicação intermitente limitante (N = 12) ou lesão trófica e/ou dor de repouso (N = 48). Resultados: Houve associação significante entre idade (p = 0,04) e cardiopatia isquêmica (p = 0,04) com aterosclerose da artéria mesentérica superior. Os fatores de risco não mostraram associação significante com presença de estenose do tronco celíaco. Observou-se associação significante entre arteriopatia dos membros inferiores e lesão estenótica da artéria mesentérica superior (p = 0,006) e do tronco celíaco (p < 0,001). Conclusões: Na ecografia vascular, o achado de arteriopatia periférica sugere presença de lesão estenótica em artéria mesentérica superior e/ou tronco celíaco. A aterosclerose na artéria mesentérica superior está associada com cardiopatia isquêmica e idade avançada.Background: The occasional relationship between arterial atherosclerosis of lower limbs and atherosclerosis of intestinal arteries has not been fully studied yet. Objective: To assess the presence of lesions with &#8805; 70% stenosis in the superior mesenteric artery and/or in the celiac trunk in patients with chronic obstructive arteriopathy of the lower limbs using vascular ultrasound (Doppler). Method: Two groups were involved, a study group and a control group, each comprising 60 patients (40 men and 20 women). The study group consisted of patients with chronic obstructive arterial disease of the lower limbs, limiting intermittent claudication or rest pain, and/or trophic lesions of the extremities but no gastrointestinal complaints. The control group comprised patients without obstructive arterial disease of the lower limbs or gastrointestinal complaints. The presence of diabetes mellitus, arterial hypertension, obesity, angina/infarct, smoking or dyslipidemia was considered a risk factor. All patients were submitted to vascular ultrasound of the celiac trunk and superior mesenteric artery. The patients of the study group were divided according to the presence of limiting intermittent claudication (n = 12) or trophic lesion and/or rest pain (n = 48). Results: A significant association was found between age (p = 0.04) and presence of ischemic cardiopathy (p = 0.04) with atherosclerosis of the superior mesenteric artery. The risk factors showed no significant association with presence of stenosis of the celiac trunk. A significant association was found between the presence of arteriopathy of the lower limbs and stenotic lesion of the superior mesenteric artery (p = 0.006) and the celiac trunk (p < 0.001). Conclusions: On vascular ultrasound, a finding of peripheral arteriopathy of the lower limbs suggests the presence of stenotic lesion in the superior mesenteric artery and /or the celiac trunk. The atherosclerosis in the superior mesenteric artery is associated with ischemic cardiopathy and advanced age
