Discontinuation of chronic haemodialysis after control of arterial hypertension; long term follow-up.

Five patients with varying chronic renal diseases had to be started on haemodialysis with malignant hypertension. After several months, dialysis treatment could be interrupted when long term blood pressure control had been attained. In three of them no long term complications were observed and renal function has continued to improve. In the two other patients, uncontrolled hypertension or acute infection made a return to haemodialysis imperative. In the case of malignant hypertension, the arteriolar necrosis has been shown to be reversible.
