NCT00716404
This is a prospective, observational, multi-center study with consecutive enrollment. Up to 1,000 patients will be enrolled. The objective of this post-marketing surveillance study is to collect clinical usage patterns of the Benephit Infusion Systems. As a result, FlowMedica will be able to: 1. Better understand and quantify usage patterns including patient characteristics, adjunctive procedures, and infusion agents. 2. Collect user-interface information and overall customer satisfaction. 3. Monitor post-marketing device performance.

To study whether pentoxifylline has additive renoprotective effect in patients taking ARB
NCT00868972
Atherosclerotic renal artery stenosis (ARAS) is associated with progressive loss of renal function, refractory hypertension and flushing edema, responsible for mortality and morbidity, especially in the elderly. Current treatment includes restoration of the renal arterial lumen by endovascular stent placement and/or intensive medical therapy. There is no unanimous consent on which patients could benefice of the endovascular procedure due to the high rate of renal adverse events especially linked to atheroembolic disease. Recently, renal revascularization using a device which consents distal embolic protection of the kidney demonstrated to be a "safe" auxiliary procedure in a few non randomized studies. Interestingly atheromatous debris was detected in 60 to 80% of these devices analyzed after the procedure suggesting that these devices could prevent atheroembolism in a substantial proportion of patients. On the other hand, only a randomized controlled study can prove that renal stent with distal embolic protection is superior to renal stent alone in preserving kidney function. Therefore, the present study aims to compare the effects of renal artery stent placement with or without distal embolic protection on renal function in ARAS patients. Method: Patients with an ARAS of ≥70% and hypertension not responsive to at least 2 antihypertensive medications and/or renal failure (estimated GFR \<60 mL/min/1.73 m2 are randomly assigned to stent placement alone or stent placement with distal embolic protection (FILTER WIRE EX; Cordis Endovascular, USA). Other medications consist of statins, anti-hypertensive drugs and antiplatelet therapy. Patients are followed for 3 months. The primary outcome of this study is a statistical significant difference in kidney function measured as Cr clearance and cystatin C level in the 2 groups at three months. The trial will include 150 patients.
