A s the prevalence and treatment of renal artery stenosis become more common, newer challenges arise. This case illustrates three such challenges: (1) the variable anatomy of the perirenal aorta, (2) the etiology and hemodynamic effect of renal artery lesions, and (3) the presence of restenosis. Renal artery angioplasty and stenting via the retrograde femoral approach can sometimes be difficult...

BACKGROUND Increased prevalence of various vascular diseases is common in type 2 diabetes mellitus. However, the increased prevalence of renal artery atheroma resulting in renal artery stenosis in patients with diabetes mellitus has not been fully assessed. We used magnetic resonance angiography to assess the prevalence of renal artery stenosis in a group of patients with hypertension and type ...

Introduction: The Persian squirrel (Sciurus anomalus) is considered the only well-known species of the family Sciuridae in the Middle East. Since some people keep this squirrel as a domestic pet, their attendance at veterinary clinics is increasing. So far, no study has been conducted on the arterial supply of the pelvic cavity and limb in the squirrel. Hence, this research was performed to fil...

renal ischemia-reperfusion (ir) injury is a common problem in kidney transplantation. there is increasing evidence about the role of the reactive oxygen species (ros) in these injuries and endogenous antioxidants seem to have an important role in decreasing the renal tissue injury. the aim of this study was to investigate the effects of kidney ir on renal antioxidant enzymes activity such as ca...

the renal transplantation program in iran had substantially been lagged behind in comparison to hemodialysis until 1985. between 1979-1984, due to lack of the facilities, over 400 iranian patients went abroad and underwent renal transplantation there. in order to evaluate the outcome of these transplants, all medical records of a nephrology clinic between the years 1978-1990 were reviewed and t...

Eklöf, H. 2005. On renal artery stenosis. 54 pp. Uppsala. ISBN 91-506-1824-5. Renal artery stenosis (RAS) is a potentially curable cause of hypertension and azotemia. Besides intra-arterial renal angiography there are several non-invasive techniques utilized to diagnose patients with suspicion of renal artery stenosis. Removing the stenosis by revascularization to restore unobstructed blood flo...

Renal artery thrombosis secondary to blunt abdominal trauma is distinctly rare. We report three cases of unilateral real artery thrombosis patients in our hospital and analyze its clinical diagnosis, therapeutic to the literature on the subject. In light of the classification of traumatic renal pedicle is not very distinct yet, we classify renal artery thrombosis for blunt abdominal trauma as a...

BACKGROUND Acute thrombosis of a transplanted renal artery is a serious vascular complication following renal allograft transplantation, which usually occurs within the first month after transplantation and often results in graft loss. It rarely occurs beyond the first month, except in a rejected kidney or in a kidney with high-grade transplant renal artery stenosis. RESULT A 65-year-old male...

Objective To investigate the potential role of alpha1-adrenoceptor (α1-AR) in the pathogenesis of hepatorenal syndrome. Methods Hepatorenal syndrome was induced in male rats by intraperitoneal injection of D-galactosamine and orally treatment with α1-AR antagonist tamsulosin. Hyperresponsiveness of the renal artery contraction was evaluated by the laser-Doppler flowmetry and multimyograph sys...
