The authors evaluated the effectiveness of percutaneous renal revascularization (PRR) with stenting for the treatment of atherosclerotic renal artery stenosis (ARAS) in patients with coronary artery disease and the usefulness of captopril renal scintigraphy for predicting clinical outcomes after PRR. Sixty-four consecutive patients, referred for evaluation of suspected ARAS, after coronary angiography, underwent baseline captopril renal scintigraphy followed by renal angiography. Forty-four patients (68.7%) were diagnosed with a significant ARAS≥ 60% and were treated with PRR plus medical therapy. Twenty-four months after PRR, 86.4% and 73.3% of patients showed a hypertension and renal benefit, respectively. Captopril renal scintigraphy positivity had moderate sensitivity and high specificity in predicting a hypertension and renal benefit. In patients with ARAS≥ 70%, the sensitivity and specificity were 100% for both a hypertension and renal benefit.PRR for ARAS conferred a substantial benefit in patients with a high coronary artery disease burden. Captopril renal scintigraphy was highly accurate in predicting clinical outcomes.

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...
Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are the 2 current standard treatments for carotid artery stenosis. There is still no well-defined consensus with regard to their superior...
Results from studies investigating the effect of contralateral carotid artery occlusion (CCO) in patients with carotid artery stenosis undergoing carotid artery endarterectomy (CEA) or carotid artery ...
The ANDORRA study is a, multicenter, prospective, open, randomized, controlled blinded endpoint trial (PROBE) comparing two treatment strategies (renal artery stenting + standardized and o...
Although expert consensuses recommend the use of statins in the treatment of atherosclerotic renal artery stenosis, in patients with severe atherosclerotic renal artery stenosis undergoing...
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...
This study will compare medical therapy plus stenting of hemodynamically significant renal artery stenoses versus medical therapy alone in patients with systolic hypertension and renal art...
The interest of renal angioplasty in the nosological framework of atherosclerotic stenosis has been significantly challenged by STAR and ASTRAL clinical trials in 2009, confirmed by the CO...
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.
Left RENAL VEIN compression between the AORTA, ABDOMINAL and the SUPERIOR MESENTERIC ARTERY. Variable symptoms include HYPERTENSION, RENOVASCULAR; HEMATURIA; and VARICOSE VEINS.
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.
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
Chronic kidney disease (CKD), also known as chronic renal disease, is a progressive loss in renal function over a period of months or years. The symptoms of worsening kidney function are non-specific, and might include feeling generally unwell and experi...
Nephrology - kidney function
Nephrology is a specialty of medicine and pediatrics that concerns itself with the study of normal kidney function, kidney problems, the treatment of kidney problems and renal replacement therapy (dialysis and kidney transplantation). Systemic conditions...
