Renal Artery Denervation by Vincristine

Bilateral renal artery stenosis after renal denervation.

Severe Renal Artery Stenosis After Renal Sympathetic Denervation.

W e present the case of a 73-year-old woman scheduled for renal angiography for severe recurrent refractory arterial hypertension 2 months after sympathetic renal denervation with the EnligHTN multielectrode catheter system (St Jude Medical, Saint Paul, Minnesota). The angiogram confirmed right renal artery subocclusive stenosis at the site of previous radiofrequency application (Figure 1). Aft...

Chemical denervation of the renal artery with vincristine for the treatment of resistant arterial hypertension: first-in-man application.

Renal artery denervation has recently emerged as a novel therapy for patients with resistant hypertension. Clinical results from renal sympathetic denervation support the safety and efficacy of this method over a period of 18 months. However, several limitations have been reported. Previous studies have shown that chemical denervation by vincristine is safe and effective in an experimental mode...

MITRAL STENOSIS COMPLICATED BY RENAL ARTERY EMBOLISM

Six patients with mitral stenosis complicated by renal artery embolism studied prospectively are presented. In five patients there was unilateral and in one patient bilateral renal artery involvement. The diagnosis was confirmed by intravenous pyelography, retrograde pyelography, renal angiography, renal scan or a combination of these. All had atrial fibrillation, proteinuria and elevated ...

Effects of Renal Sympathetic Denervation in Renal Artery Diameter Evaluated By Quantitative Angiography

Background: Percutaneous renal sympathetic denervation was developed as an adjunct method to treat clinical conditions associated to sympathetic hyperactivity. Percutaneous renal sympathetic denervation increases the renal blood flow and reduces vasoconstriction. The effects of percutaneous renal sympathetic denervation in renal artery diameter have not been reported. Our objective was to evalu...
