24 patients with renovascular hypertension were operated from 1995 to 1997. Patients were divided into three groups: group I-atherosclerotic stricture of renal arteries with or without aorta stenosis (13), group II-fibromuscular dysplasia (8), group III-stricture of vascular anastomosis after renal transplantation (5). All patients were disqualified from PTA. Operations of reanastomosis of renal arteries to aorta or prosthesis and TEA dominated in group I, the operation of choice in groups II and III was plastic procedure with patch or venous graft. Authors conclude that surgical treatment of renovascular hypertension is an efficient method of treatment in case of disqualification from PTA and the way of reconstruction should be dependent on the reason of renovascular hypertension.

Proteinuria, especially albuminuria, serves as an independent risk factor for progression in cardiovascular and renal diseases. Clinical and experimental studies have demonstrated that renal nerves contribute to renal dysfunction in arterial hypertension (AH). This study hypothesizes that renal nerves mediate the mechanisms of protein endocytosis by proximal tubule epithelial cells (PTEC) and glomerular function; with dysregulation of the renal nerves contributing to proteinuria in Wistar rats with renovascular hypertension (2-kidney, 1-clip model, 2K-1C).

This case report underscores the importance of thorough follow-up care for children recovering from COVID-19, with a focus on monitoring blood pressure and renal function to mitigate long-term renovascular disease.

Background: Atherosclerotic renal artery stenosis (ARAS) may provoke hypertension and/or impaired kidney function. Some patients develop uncontrolled hypertension and deteriorating kidney function despite optimal medical therapy. In these patients, endovascular treatment is an important therapeutic option.

Metabolic syndrome (MetS) is associated with low-grade inflammation, which can be exacerbated by renal artery stenosis (RAS) and renovascular hypertension, potentially worsening outcomes through pro-inflammatory cytokines. This study investigated whether mesenchymal stem/stromal cells (MSCs) could reduce fat inflammation in pigs with MetS and RAS. Twenty-four pigs were divided into Lean (control), MetS, MetS + RAS, and MetS + RAS + MSCs.

In renal vasculitis, luminal narrowing can reduce blood flow and activate the renin-angiotensin-aldosterone system, causing renovascular hypertension. We present the case of a 47-year-old man with previous intestinal tuberculosis and episodes of lumbar pain, tender erythematous nodules and arthralgias. He had grade 3 hypertension, unresponsive to treatment, with left ventricular concentric hypertrophy and chronic kidney disease.
