Abstract
Renovascular hypertension is one of the most common forms of secondary hypertension. Over 95% of cases of renovascular hypertension are due either to atherosclerosis of the main renal artery trunks or to fibromuscular dysplasia. These two causes of renal artery stenosis have been extensively discussed in recent reviews and consensus. The aim of the current article is to provide comprehensive and up-to-date information on the remaining causes. While these causes are rare or extremely rare, etiologic and differential diagnosis matters both for prognosis and management. Therefore, the clinician cannot ignore them. For didactic reasons, we have grouped these different entities into stenotic lesions (neurofibromatosis type 1 and other rare syndromes, dissection, arteritis, and segmental arterial mediolysis) often associated with aortic coarctation and other arterial abnormalities, and nonstenotic lesions, where hypertension is secondary to compression of adjacent arteries and changes in arterial pulsatility (aneurysm) or to the formation of a shunt, leading to kidney ischemia (arteriovenous fistula). Finally, thrombotic disorders of the renal artery may also be responsible for renovascular hypertension. Although thrombotic/embolic lesions do not represent primary vessel wall disease, they are characterized by frequent macrovascular involvement. In this review, we illustrate the most characteristic aspects of these different entities responsible for renovascular hypertension and discuss their prevalence, pathophysiology, clinical presentation, management, and prognosis.

Abstract
Congenital renal arteriovenous fistula (rAVF) is a rare and often underdiagnosed clinical condition. Here, we present a case of a large congenital rAVF in an 81-year-old woman with a right flank bruit and high-output heart failure. The rAVF was successfully treated with percutaneous endovascular coil embolization. Complications included a small right renal hematoma, mild contrast-induced nephropathy, and small right renal infarct in the lower pole. Postoperatively, the patient had complete resolution of symptoms with salvage of the kidney. She has been observed annually for 5 years with computed tomography scan and ultrasound examination.

Abstract
An idiopathic renal arteriovenous (AV) fistula is a rare malformation of the kidney that may present insidiously with heart failure or hematuria. The treatment may be challenging due to large fistula size that may limit endovascular management. The authors report a case of an 85-year-old Caucasian woman who presented with acute heart failure and was found to have a right renal AV fistula. Since she had no prior history of renal intervention or trauma, a diagnosis of idiopathic renal AV fistula was made. She was managed by endoluminal occlusion using multiple stainless steel coils and Amplatzer vascular plug II device. The follow-up computed tomography showed complete occlusion of the fistula. This report highlights the late presentation of this rare disease and presents the utility of the combination of coils and Amplatzer device for management of a large fistula. It also reiterates that even if large, these fistulas can be managed by endovascular occlusion.

Abstract
Delayed hematuria following blunt trauma is rare but can be significant. We describe an unusual delayed presentation of renal arteriovenous fistula following blunt trauma.A gentleman presented with hematuria and clot colic. Following initial investigations, renal arteriography showed an arteriovenous fistula in the mid-pole of the right kidney. The fistula was successfully occluded by super-selective coil embolization. Although this case is an unusual presentation, AV fistulae must be ruled out in management of patients of hematuria.
