[Atherosclerotic stenosis of the main branches of abdominal aorta. (Prevalence in patients with lower limb occlusive vascular disease)]. / Estenose aterosclerótica dos principais troncos arteriais da aorta abdominal. (Prevalência em pacientes com arteriopatia oclusiva dos membros inferiores).

ABSTRACT

The authors present the radiographical study of the aortographies of 100 consecutive patients with symptomatic atherosclerotic ischemia of the lower limbs in whom were appraised the stenosis of the celiac trunk, superior mesenteric artery, renal arteries and the presence of the inferior mesenteric artery. The parameters observed were age, sex, solitary and concomitant stenosis. Seven patients were excluded six because of arteritis and one because could not be analyzed. Sixty four (68.81%) of the remaining 93 patients had important stenosis (> 30%) of one or more branches of the abdominal aorta, which had a steep raise in number from the 60 decade on. There was no difference regarding to the sex of the patients. The more frequently found solitary stenosis was that of the celiac trunk (16-16.1%) followed by the renal (13-13.0%) and in the concomitant was that of the celiac trunk/renal artery (8-8.6%) and celiac trunk/superior mesenteric artery (5-5.3%). They conclude that in spite of the great number of stenosis of the branches of the abdominal aorta in this kind of patients, there was a low incidence of the concomitant stenosis of the celiac trank/superior mesenteric artery, being difficult to characterize radiologically the digestive ischemic syndrome. They point out that this highly selected group of patients, because of their basic disease, should be more extensively studied in order to identify the results of those vascular stenosis on their digestive tract and orient its eventual treatment.
