Smoking and atheromatous stenoses of renal arteries

Renal vascular pathologies are important causes of the chronic renal failur e, progression. In these pathologies, the role of smoking in so far as fact or of risk was discussed. This work aims to evaluate the effect of smoking exposure on renal arteries of patients with both renal failure and hyperten sion. 67 patients more than 50 years old, having both renal failure and hypertens ion, have been explored by arteriography. The active smoking was required a mong all patients. Patients were classified in 2 groups: group (I) of 45 pa tients with one or more atheromatous stenoses of renal arteries considered to be significant and group (II) of 22 patients without significant atherom atous stenoses of renal arteries. [GRAPHICS] 80,5% of patients of group (I) have smoked against only 44,4% in group (II) . The fact that the presence of atheromatous stenoses of renal arteries was connected to the number of cigarettes and the exposure time, and not to th e current comportment of patients towards smoking, this suggested a cumulat ive effect of smoking. Conclusion: This work shown a relation between the consumption of smoking a nd the existence of atheromatous stenoses of renal arteries, a reason moreo ver to fight against smoking. The prevention of smoking intoxication appear s important to decrease the incidence of the renal vascular pathologies.
