Different outcomes of atherosclerotic renal artery stenosis managed with stenting: results from a cohort study.

Background: To determine whether the type of renal artery stenosis and the rapid decline of renal function may have an impact on renal outcome after stenting.

Methods: Thirty patients with chronic kidney disease stages 3-4 and renal artery stenosis underwent stenting. The mean follow-up was 33 months; the change of estimated glomerular filtration rate was expressed as negative or positive value in mL/mo (ΔGFR).

Continuing follow-up of malignant hypertension.

The history of accelerated (malignant) hypertension is reviewed, and unsolved problems related to the disease are illustrated, including its relationship to malignant nephrosclerosis, as well as terminology, current frequency and treatment. Over the past 25 years, out of a series of 131 patients, 53 were classified as suffering from essential malignant hypertension, the only suitable model on which the effects of pharmacological treatment on the disease can correctly be evaluated. In 2000, there were 24 survivors in our series and the maximum follow-up was 290 months.
