CASE REPORT: LERICHE SYNDROME (AORTOILIAC OCCLUSIVE DISEASE - AIOD) IN “SAN JUAN” GENERAL HOSPITAL IN THE CITY OF RIOBAMBA

Abstract

Aortoiliac occlusive disease (AOIAD), also known as Leriche syndrome, is a pathology characterized by progressive occlusion of the abdominal portion of the aorta, the common iliac arteries from their bifurcation below the exit of both renal arteries. The incidence and prevalence of this syndrome are unknown since it usually does not present symptoms. Factors such as smoking, arterial hypertension, dyslipidemia, obesity and diabetes are predisposing factors for the development of this condition, which occurs as a consequence of atherosclerosis accompanied by a lesion at the arterial wall level plus a state of hypercoagulability. The clinical manifestations are variable, it is mainly an asymptomatic disease, but as the condition progresses patients may present intermittent claudication. The diagnosis is based on invasive and non-invasive methods and there is also an anatomical classification system that is important for the knowledge of the clinical manifestations and the choice of treatment. For EOAI, management includes lifestyle changes associated with conservative or surgical treatment, which will depend on the individualization of each patient.
