Renal artery stenosis (RAS) and renal complications emerge in some patients after endovascular aneurysm repair (EVAR) to treat abdominal aorta aneurysm (AAA). The mechanisms for the causes of these problems are not clear. We hypothesized that for EVAR patients, lower limb exercise could negatively influence the physiology of the renal artery and the renal function, by decreasing the blood flow ...

The subject was a white male who died of a cerebral hemorrhage at sixty-six years of age. The right internal spermatic artery, instead of having its origin from the aorta at the normal level, arose above that of the renal artery. It passed caudally between the right renal artery and the renal vein; from this point on, it had a normal descent to the testis. An anomalous vascular connection in th...

BACKGROUND Renal artery stenosis is a common cause of secondary hypertension refractory to medical therapy. Percutaneous angioplasty along with metallic stent placement has been described as an effective treatment for revascularization of the renal artery. CASE REPORT A 54-year-old woman affected by paranoid schizophrenia with a history of hypertension and chronic renal failure due to renal a...

A 63-year-old woman with extensive atherosclerotic vascular disease, including long-standing renal artery stenosis, was evaluated for newly uncontrolled hypertension with frequent headaches despite the use of 4 antihypertensive agents. Her blood pressure had been well controlled previously. She had a remote history of right renal artery occlusion and had undergone left renal artery stenting 9 y...

The most frequent anatomical variations of the renal arterial system are accessory arteries (supernumerary arteries) and aberrant arteries, which occur in varying numbers among various ethnic racial groups. Prior to surgery, understanding these is crucial because it affects decision use donor kidneys, planning partial nephrectomy, other urological procedures. Along with main artery on same side...

INTRODUCTION The dissecting aneurysm of renal artery is a form of renal artery occlusive disease that is infrequently recognized in the literature. However, when encountered, it is of great clinical significance because symptoms related to aneurysm are rarely seen and there is risk of its rupture. CASE PRESENTATION The present case was a 30 year old Indian male, who presented with recurrent e...

Neurofibromatosis (NF1) is a relatively common autosomal dominant disorder. Secondary causes of hypertension, such as renovascular disease, coarctation of the abdominal aorta or phaeochromocytoma, may be identified in up to 1% of patients with NF1. Usually, renal angiography, which is always used to confirm the diagnosis of renovascular hypertension, reveals stenoses and rarely bilateral or uni...
