[Prevalence of renal artery stenosis in patients with critical limb ischemia]. / Prevalencia de estenosis de la arteria renal en los pacientes con isquemia crónica grave de extremidades inferiores.

BACKGROUND AND OBJECTIVE: Our purpose was to evaluate the prevalence of renal artery stenosis in patients with critical limb ischemia and to study any clinical or laboratory indicator that could predict this association. PATIENTS AND METHOD: One hundred consecutive patients with critical limb ischemia evaluated by angiogram were included in the study from January to July 2003. Cardiovascular risk factors and renal function were analyzed. RESULTS: One hundred angiographic studies have been analyzed. Thirty nine (39%) of our patients had some type of pathology of the renal artery but the rest, 61 (61%), had normal and healthy renal arteries. In 5 patients, a bilateral renal pathology was found. Severe disease (> 60% stenosis, bilateral or renal occlusion) was present in 15 cases including 6 occlusions. Once we compared the patients with healthy renal arteries with the patients with different degrees of stenosis, we did not appreciate significant differences in hypertension, diabetes, coronary disease or smoking habit, nor with laboratory data such as creatinine, urea, c-reactive protein, total cholesterol or atherogenic index. No differences were found either comparing patients with normal renal artery with patients with bilateral pathology or with unilateral occlusion. CONCLUSIONS: There is a high prevalence of renal artery pathology in patients with critical limb ischemia although we have not found any clinical or laboratory factors useful to identify them.

Fundamento y objetivo: Evaluar la prevalencia de la estenosis de la arteria renal en los pacientes con isquemia grave de las extremidades inferiores, y estudiar si existe algún indicador clínico o analítico que pueda ser útil para diferenciar a la población con enfermedad renal del resto de pacientes. Pacientes y método: Se ha estudiado prospectivamente mediante arteriografía renal a 100 pacientes ingresados de forma consecutiva en nuestro servicio por isquemia crónica de extremidades inferiores entre enero y julio de 2003. Se analizaron los factores de riesgo cardiovascular y la función renal mediante analítica. Resultados: Se realizaron 100 arteriografías. En 39 (39%) se observó enfermedad de arterias renales, mientras que éstas eran normales en 61 (61%). En 5 pacientes se encontró afectación bilateral. Se halló afectación grave (estenosis > 60%, afectación bilateral u obliteración renal) en 15 casos, que incluyeron 6 obliteraciones renales. Al comparar los pacientes que presentaban arteria renal sana con los que tenían una estenosis de la arteria renal no se obtuvieron diferencias respecto a la hipertensión arterial, diabetes mellitus, cardiopatía isquémica ni tabaquismo, y tampoco hubo diferencias en los parámetros analíticos estudiados: creatinina, urea, proteína C reactiva, colesterol total e índice aterogénico. Tampoco se hallaron diferencias al comparar el grupo de pacientes con arteria renal sana con aquellos que presentaban enfermedad bilateral o con los que presentaban oclusión de una arteria renal. Conclusiones: Existe una alta prevalencia de enfermedad vascular renal en los pacientes con isquemia grave de las extremidades inferiores. A pesar de ello, no hallamos ningún marcador clínico o analítico que la identifique
