INTRODUCTION: Renovascular hypertension in children is a very rare illness. It occurs as a result of the imbalance between hypotensive and hypertensive systems. Renal ischaemia (95% of the cases) and the shortening of hipotensive factors (5% of the cases) are responsible for the production mechanism of renovascular hypertension in children. In order to make an early diagnosis regarding the renovascular hypertension in all children suffering from renovascular illnesses, blood pressure must be taken correctly and repeatedly. MATERIALS AND METHODS: This paper is a case study on 19 children with renovascular hypertension, aged between 2 and 15 years old. Most cases were divided into two groups: subjects aged 4-7 years old and subjects aged 8-12 years old. Each group represents 34.2% of all cases. The diagnosis of renovascular hypertension in those 19 children was established after correctly taking the blood pressure and comparing it with the normal values for each age. Hypertension was diagnosed before knowing its cause in 8 neglected cases. The blood pressure was repeatedly taken in the other 11 children suffering from renovascular illnesses and the diagnosis of hypertension was early established when blood pressure values increased. Previously, blood pressure was normal in these 11 cases. RESULTS: The etiopathogenical diagnosis showed parenchymal diseases in 12 cases--63.1%. Seven patients suffered from renovascular lesions--36.9%. Laboratory exams, radiology, imagistic exams, arteriography and scintigraphy were steps taken in order to establish the etiopathogenical diagnosis. These exams showed the next direct causes of renovascular hypertension: bilateral chronic pyelonephritis in 4 cases--21.4%, hydronephrosis in 3 cases--16.2%, congenital renal hypoplasia in 2 cases--10.4% and doubled kidney in 2 cases--10.4%. The other 8 cases presented acute glomerulonephritis, unilateral renal agenesis, horseshoe kidney, unilateral pyelonephritis, renal artery agenesis, renal trauma, renal abcess and Wilms tumor, one case of each illness--5.2%. The major complications were: retinopathy, chronic renal failure and stroke. CONCLUSIONS: Laboratory data are just a hint in diagnosing renovascular hypertension. However, radiology, imagistic exams, arteriography and scintigraphy are compulsory in the renourinary status and etiopathogenical diagnosis. |
