Case report: secondary hypertension in a 6-year old child with bilateral renal artery stenosis

Background. Renovascular hypertension (RVH) is an elevated blood pressure caused by partial or complete occlusion of one or both renal arteries or their branches. According to different studies, renal artery stenosis accounts for 5–10% of all cases of hypertension in children. The most common causes of renal artery stenosis are deemed to be atherosclerosis and fibromuscular dysplasia.Case description. The article describes clinical case of a newly diagnosed renovascular hypertension amid background of fibromuscular dysplasia of renal arteries in a 6-year old child, particulars of the clinical course, laboratory and instrumental methods of investigation and treatment including aortography and balloon angioplasty of renal arteries.Conclusion. This case report illustrates that in the absence of complaints and pronounced clinical symptoms the diagnosis of renovascular hypertension in a 6-year old child could not be established for a long time. Timely detection of elevated BP in children, including the young ones, not only during visiting specialist physicians but also during prophylactic examination by pediatrician, is required for early diagnosis of the disease and development of the examination and treatment strategy.
