branches of the abdominal aorta. A single renal artery supplies each kidney in most individuals. The renal arteries typically arise just below the origin site of the superior mesenteric artery and they travel laterally behind the renal veins (1, 2). Among the various types of renal artery anomalies, the most clinically important variation is the accessory renal artery. Accessory renal arteries ...

Renal artery stenosis is a cause of secondary hypertension which can be cured by surgical or radiological intervention such as percutaneous transluminal renal artery stent placement. In this case we present a subcapsular hematoma of the kidney, a complication following percutaneous transluminal stent placement in the renal artery. Reperfusion injury to the kidney may be a possible mechanism of ...

Endovascular aneurysm repair (EVAR) of abdominal aorta is a valuable treatment option in selected patients with abdominal aortic aneurysm. Renal artery occlusion is a serious complication after EVAR and may progress to permanent renal injury requiring hemodialysis. In this report, case of unexpected renal artery occlusion after EVAR treated with renal artery stenting in the late postoperative p...

Flash pulmonary edema frequently develop in case of bilateral renal artery stenosis and unilateral renal artery stenosis with functional solitary kidney. In some rare cases, unilateral renal artery stenosis with bilaterally functional kidneys may also lead to flash pulmonary edema. Here, we present a case of flash pulmonary edema caused by accessory renal artery stenosis. To our knowledge, it i...

BACKGROUND/AIMS Renal blood flow (RBF) is tightly regulated by several intrinsic pathways in maintaining optimal kidney blood supply. Using a rat model of aortocaval (AC) fistula, we investigated remodeling of the renal artery following prolonged increased blood flow. METHODS An AC fistula was created in the infrarenal aorta of anesthetized rats, and changes of blood flow in the renal artery ...

OBJECTIVE It is important to identify patients at risk for atherosclerotic renal artery stenosis because renal artery stenosis is a progressive disease and a potentially correctable problem. This study is to evaluate the prevalence of angiographically-determined renal artery stenosis in a patient population undergoing routine coronary angiography, and to identify the risk factors for renal arte...

BACKGROUND Single-electrode ablation of the main renal artery for renal sympathetic denervation showed mixed blood pressure (BP)-lowering effects. Further improvement of the technique seems crucial to optimize effectiveness of the procedure. Because sympathetic nerve fibers are closer to the lumen in the distal part of the renal artery, treatment of the distal main artery and its branches has b...

Renal artery disease is an important cause of both renal failure and hypertension. Duplex ultrasound is a reliable noninvasive method for classifying the severity of renal artery lesions and can be repeated to follow the course of the disease over time. The purpose of this study was to determine the changes in kidney size associated with various degrees of renal artery disease. Serial kidney le...

The effects of graded renal artery stenosis on renal and systemic hemodynamics and plasma renin activity (PRA) were studied in conscious, chronically instrumented dogs. In mild and moderate stenosis (following rapid reduction in distal renal artery pressure to 60 or 40 mm Hg) there was initial vasodilatibn followed by prompt restoration within 5-30 minutes of renal artery pressure and vascular ...

The renal arteries are a pair of lateral branches arising from the abdominal aorta below the level of superior mesenteric artery at the upper lumbar level (L1-L3). The paired renal arteries take about 20% of the cardiac output to supply organs that represent less than one-hundredth of total body weight [1]. The right renal artery is longer in its course owing to the location of the abdominal ao...
