Hypertensive Encephalopathy Caused by Fibromuscular Dysplasia of Renal Arteries in a Child
نویسندگان
چکیده
Systemic hypertension is uncommon in children. It is usually secondary to underlying diseases. Here, we present an 11-year-old boy suffering from critical renal artery stenosis with unusual initial presentation of status epilepticus and hypertensive cerebellar encephalopathy. Angiography revealed bilateral renal arteries fibromuscular dysplasia. The encephalopathy improved dramatically after renal artery angioplasty. This patient reminds us renovascular disorder can be the cause of neurological diseases. Though he has bilateral renal arterial stenosis, we only dilated the focal critical stenosis of the right renal artery and his symptoms improved.

Background: Renal artery stenosis, which is defined as narrowing of one or both renal arteries or their branches, is one of the most common causes of secondary hypertension. The majority of renal vascular lesions show either fibromuscular dysplasia or atherosclerosis. Fibromuscular dysplasia is a common cause of renovascular hypertension in younger patients, and 90% of patients are young wome...
متن کاملEncephalopathy in renovascular hypertension associated with the use of oral contraceptives.
Two female patients aged 19 years and 27 years presented with hypertensive encephalopathy and were subsequently found to have renal artery stenosis due to fibromuscular dysplasia. Both patients had had normal blood pressures recorded within the previous 6 months whilst taking the oral contraceptive pill. Their neurological state returned to normal with hypertensive control and in one case the h...
متن کاملAcute aortic dissection and stroke in multivessel fibromuscular dysplasia.
Fibromuscular dysplasia is a rare, nonatherosclerotic, noninflammatory vascular disease that typically affects women between the ages of 20 and 60 years. Although any artery can be affected, fibromuscular dysplasia most commonly affects the renal and carotid arteries. Fibromuscular dysplasia of the renal arteries usually presents with hypertension, while carotid or vertebral artery disease caus...
متن کاملFibromuscular dysplasia in an accessory renal artery causing renovascular hypertension: a case report
BACKGROUND Renovascular hypertension is defined as hypertension caused by renal artery stenosis. The two main etiologies are atherosclerosis and fibromuscular dysplasia. Fibromuscular dysplasia in an accessory renal artery as a cause of renovascular hypertension is uncommon. CASE PRESENTATION In this report, we present a relatively uncommon case of renovascular hypertension in a 35-year-old f...
متن کاملPercutaneous transluminal renal angioplasty in nonatherosclerotic renovascular hypertension. Long-term results.
Nineteen stenotic arteries in 16 patients with severe renovascular hypertension of nonatherosclerotic nature (fibromuscular dysplasia in 13, neurofibromatosis in 3) were treated with percutaneous transluminal renal angioplasty. The procedure was technically successful in 12 of 14 (86%) stenoses in the fibromuscular dysplasia subgroup but in only one of five (20%) lesions in the neurofibromatosi...
