A multicenter prospective registry planned to recruit more than 5 000 patients with renal artery stenosis was carried out in China. This primary purpose of this study was to evaluate the s...
All patients referred for coronary angiography will simultaneously be evaluated for renal artery stenosis and then stenosis more than 50% will be analyzed according to clinical conditions,...
This study will use PBV technique to quantitatively assess the improvement of renal perfusion before and after endovascular treatment (EVT) of renal artery stenosis.
The purpose of this trial is to test how well the iCAST™ RX Stent works in patients diagnosed with atherosclerotic renal artery stenosis and whether or not increased blood flow by the st...
The clinical investigation is a prospective, international, multi-centre, randomized (1:1) trial with follow ups at 2, 6, 12 months and 3 years. The purpose of the study is to evaluate th...
Randomized trials have failed to show clinical benefit in patients with atherosclerotic renal artery stenosis who were treated with angioplasty with or without stenting. However, these studies were do...
Renal artery stenosis (RAS) is a known cause of secondary hypertension and renal failure. Although renal artery angiography is the gold standard for diagnosing RAS, a simple method to estimate if pati...
Renal artery stenosis (RAS) is a leading cause of hypertension, renal failure, pulmonary edema, and loss of renal mass. Atherothrombotic renal disease is a well-described entity, known primarily for i...
Renal artery stenosis represents a rare cause of neonatal arterial hypertension of renovascular origin, having been described few cases in the literature at this stage of life. Most patients with this...
The occurrence of transplant renal artery stenosis (TRAS) ranges from 1% to 23%, and is associated with resistant hypertension, volume overload, graft dysfunction and poor long-term graft and patient ...
Narrowing or occlusion of the RENAL ARTERY or arteries. It is due usually to ATHEROSCLEROSIS; FIBROMUSCULAR DYSPLASIA; THROMBOSIS; EMBOLISM, or external pressure. The reduced renal perfusion can lead to renovascular hypertension (HYPERTENSION, RENOVASCULAR).
Use of a balloon catheter for dilatation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of balloon dilatation in coronary arteries, ANGIOPLASTY, TRANSLUMINAL, PERCUTANEOUS CORONARY is available.
A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.
Transient complete or partial monocular blindness due to retinal ischemia. This may be caused by emboli from the CAROTID ARTERY (usually in association with CAROTID STENOSIS) and other locations that enter the central RETINAL ARTERY. (From Adams et al., Principles of Neurology, 6th ed, p245)
Narrowing below the PULMONARY VALVE or well below it in the infundibuluar chamber where the pulmonary artery originates, usually caused by a defective VENTRICULAR SEPTUM or presence of fibrous tissues. It is characterized by restricted blood outflow from the RIGHT VENTRICLE into the PULMONARY ARTERY, exertional fatigue, DYSPNEA, and chest discomfort.
