Percutaneous transluminal renal angioplasty (PTRA) as a method of therapy for renovascular hypertension in children.

The results of PTRA in treatment of renovascular hypertension in four children aged 5, 7, 13 and 15 are presented. All patients suffered from severe hypertension. Tests showed all of them to have fibromuscular dysplasia stenosis of the main renal artery and significant lateralization of renin levels.

[Renin levels in renal veins in patients with essential arterial hypertension].

The data on plasma renin activity (PRA) obtained by catheterization of renal veins in 272 patients with essential arterial hypertension (EH) are reported. In order to exclude a secondary nature of hypertension, all patients were hospitalized and submitted to the extensive clinical and laboratory examinations (according to the protocol) including renal angiography. The aim of the work was to get evidence whether in the apparently homogeneous group of patients with EH there are differences in renin activity between the renal veins giving the quotient (Q) higher than 1.
