Radiofrequency (RF) catheter ablation of the renal artery is therapeutic in patients with drug-refractory essential hypertension. This study was designed to examine the role of the renal autonomic nerves and of RF application from inside the renal artery in the regulation of blood pressure (BP). An open irrigation catheter was inserted into either the left or right renal artery in 8 dogs. RF cu...

Renal artery stenosis is the most common cause of secondary hypertension. Over 90% of renal artery stenoses are caused by arteriosclerosis, the remainder resulting from fibromuscular dysplasia which usually does not lead to progressive azotemia and end stage renal disease. Renal angioplasty is the treatment of choice for fibromuscular dysplastic disease and has the potential of curing hypertens...

Renal artery dissection may be caused by iatrogenic injury, trauma, underlying arterial diseases such as fibromuscular disease, atherosclerotic disease, or connective tissue disease. Radiological imaging may be helpful in detecting renal artery pathology, such as renal artery dissection. For patients with acute, isolated renal artery dissection, surgical treatment, endovascular management, or m...

conclusions in addition to an appropriate clinical history, ct findings indicating decreased aortomesenteric angle and a shortened aortomesenteric distance can suggest the diagnosis for both the superior mesenteric artery syndrome and accompanying nutcracker syndrome. case presentation in this report, a patient is described presenting with epigastric pain and weight loss due to superior mesente...

Renal artery aneurysms involving segmental branches pose a technical challenge in repair. Both endovascular and open repair techniques have been described. This case illustrates the clinical presentation of patient with symptomatic renal aneurysm thromboembolic infarction managed laparoscopic nephrectomy, ex-vivo resection, reconstruction, autotransplantation.

BACKGROUND AND PURPOSE Renal artery lesions in moyamoya disease have been described sporadically in several case reports. The purpose of this study is to evaluate the angiographic findings of renal artery lesions in moyamoya disease and to determine the prevalence of renal artery lesions in patients with moyamoya disease. METHODS Eighty-six consecutive patients with idiopathic moyamoya diseas...

BACKGROUND Acute renal artery thrombosis is a devastating complication of renal transplantation that can result in graft loss if not detected early. Surgical and technical errors are the major cause of renal artery thrombosis. In this article, for the first time, we are reporting a case of acute renal artery thrombosis that developed early post-transplantation due to distal renal artery stenosi...

BACKGROUND Cases of renal artery entrapment (RAE) by extrinsic compression have been infrequently reported in the literature. We aimed to describe RAE and elucidate anatomical factors that may be related to renal artery stenosis. MATERIALS AND METHODS Two hundred and four patients' computed tomography scans made for various reasons in Radiology Department from 2011 to 2015 were retrospectivel...

OBJECTIVE: The purpose of this study was to evaluate the association between the presence of clinical symptoms of peripheral artery disease and severe renal artery stenosis in patients referred for renal angiography. METHOD: We included 82 patients with clinical suspicion of renovascular hypertension and performed an imaging investigation (renal Doppler ultrasound and/or renal scintigraphy) f...
