[TREATMENT OF SEVERE ATHEROSCLEROTIC RENAL ARTERY STENOSIS WITH ACUTE KIDNEY INJURY REQUIRING HEMODIALYSIS BY PERCUTANEOUS TRANSLUMINAL RENAL ANGIOPLASTY AND STENT IMPLANTATION].

Harefuah 2021 Apr;160(4):210-214

Institute of Nephrology and Hypertension, Sheba Medical Center, Israel.

Introduction: Treatment of atherosclerotic renal artery stenosis (RAS) is still controversial. Several randomized controlled trials have shown that percutaneous transluminal renal angioplasty with stenting (PTRAS) is not superior to medical treatment, and the procedure is commonly reserved for malignant hypertension, flash pulmonary edema or deterioration of kidney function. The most challenging symptomatic RAS cases are patients with severe stenosis resulting in acute kidney injury (AKI) requiring acute hemodialysis. Read More

Acute Severe Renal Artery Stenosis Presenting as Acute Kidney Injury with Severe Hypertension, and Active Urine Sediment.

Can J Cardiol 2021 Apr 20. Epub 2021 Apr 20.

Division of Nephrology, Department of Medicine, The Ottawa Hospital, University of Ottawa. Electronic address:

We present a case of severe renal artery stenosis that mimicked a rapidly progressive glomerulonephritis with acute kidney injury, active urine sediments and severe hypertension. Simultaneous presence of secondary hyperaldosteronism and hypokalemia prompted renal angiogram and subsequent renal artery angioplasty and stenting, thus leading to rapid resolution of acute kidney injury, proteinuria, and hypertension. Our case emphasizes the importance and benefits of prompt diagnosis and revascularization of acute severe renal artery stenosis in a patient with history of atherosclerotic renovascular disease presenting with sudden onset of severe hypertension and acute kidney injury with active urine sediment mimicking rapidly progressive glomerulonephritis.

Renovascular hypertension in pediatric patients: update on diagnosis and management.

Pediatr Nephrol 2021 Apr 13. Epub 2021 Apr 13.

Interdisciplinary Laboratory of Medical Investigation, Faculty of Medicine, Federal University of Minas Gerais (UFMG), Belo Horizonte, MG, Brazil.

Renovascular hypertension (RVH) is defined as an elevated blood pressure caused by kidney hypoperfusion, generally as a result of anatomic stenosis of the renal artery with consequent activation of the Renin Angiotensin-Aldosterone System. The main causes include genetic and inflammatory disorders, extrinsic compression, and idiopathic alterations. RVH is often asymptomatic and should be suspected in any child with refractory hypertension, especially if other suggestive findings are present, including those with severe hypertension, abdominal bruit, and abrupt fall of glomerular filtration rate after administration of angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers.

Internist (Berl) 2021 Mar 18;62(3):252-262. Epub 2021 Jan 18.

KfH-Nierenzentrum, Maxstraße 48, 67059, Ludwigshafen, Deutschland.

Severe arteriosclerotic stenosis of the renal artery with at least 60-70% narrowing of the lumen can lead to various diseases: in the case of unilateral stenosis it can lead to renovascular hypertension, in the case of bilateral narrowing (or in a stenotic solitary kidney) also to an often progressive renal insufficiency (ischemic kidney disease) and/or to acute pulmonary edema (pulmonary flash edema). Renal artery stenosis may be treated by revascularization using either percutaneous (balloon angioplasty with or without stenting) or less commonly open surgical procedures, both with excellent primary patency rates of over 90%; however, randomized trials of catheter-based interventions have failed to demonstrate a longer term benefit with respect to blood pressure control and renal function as well as improved overall survival over optimal medicinal management alone. Due to improved clinical outcomes interventional revascularization is justified in cases with critical stenoses and clinical sequelae, such as pulmonary flash edema and progressive renal failure.

Endovascular reversal of renovascular hypertension blunts cardiac dysfunction and deformation in swine.

J Hypertens 2021 Mar;39(3):556-562

Division of Nephrology and Hypertension, Mayo Clinic, Rochester, Minnesota, USA.

Objective: Renovascular hypertension (RVH) induces hemodynamic and humoral aberrations that may impair cardiac function, structure and mechanics, including cardiac twist and deformation. Revascularization of a stenotic renal artery can decrease blood pressure (BP), but its ability to restore cardiac mechanics in RVH remains unclear. We hypothesized that percutaneous transluminal renal angioplasty (PTRA) would improve cardiac function and left ventricular (LV) deformation in swine RVH. Read More
