Abstract Background and Aims Renovascular disease is rare but important treatable cause of secondary hypertension in children. We aimed to evaluate the clinical presentations and long-term outcomes of pediatric patients with renovascular hypertension (RVH). Method We retrospectively reviewed medical records of patients with renovascular disease at our center between 1994 and 2019. Clinical courses including status of hypertension control with preservation of renal function during follow up were evaluated. Results 20 patients were diagnosed with RVH. 50 % (n = 10) were male, and median age at diagnosis was 10.1 (range 1.3 – 17.2) years, and median follow up period was 8.7 (range 0.1 – 24.6) years. 50 % (n = 10) presented with incidently detected high blood pressure (8 patients without symptoms, one with headache, and the other one with proteinuria), 25 % (n = 5) first admitted due to heart failure symptoms, and the rest (25 %, n = 5) presented with neurologic symptoms including seizure or paraplegia. Majority had no underlying disease except for 3 patients with Moyamoya disease. 80 % (n = 16) had unilateral renovascular stenosis. All patients showed elevated basal random renin activity (median 20.0, range 2.5 – 62.1 ng/ml/hr), and 45 % (n = 9) patients showed elevated basal random aldosterone level (median 822, range 266 – 2440 pg/ml). All patients needed antihypertensive medications for blood pressure control; 35 % (n = 7) of patients gained good control of blood pressure only with antihypertensive agents including angiotensin converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB), 40 % (n = 8) of patients who underwent percutaneous transluminal angioplasty all still needed antihypertensive agents including ACEI for blood pressure control. 20 % (n = 4) of the patients initially showed profoundly low relative function of involved kidney on diuretic scan, leading to nephrectomy. Three of these patients with nephrectomy successfully discontinued all antihypertensive agent gaining good control of blood pressure. The remaining one patient showed progressive deterioration of relative function on the involved side of kidney during 13 years, ended up with nephrectomy, but couldn’t discontinue ACEI. Glomerular filtration rate (GFR) was within normal range for all patients at diagnosis. For patients without nephrectomy, mean relative function of the involved kidney on diuretic scan was 33.5 ± 11.4 % at diagnosis. There was no significant change or deterioration of relative renal function during a mean follow up period of 10 ± 8 (median 11.5, range 0 – 19.5) years, although they all used ACEI/ARB. All patients including patients with nephrectomy showed normal GFR with a mean of 114.1 ± 19.5 ml/min/1.73 m2 at the last follow up. Conclusion Antihypertensive medications including ACEI and ARB were safely used with no further deterioration of the renal function of the involved side with or without angioplasty. Pediatric RVH is well managed with preserved renal function in long-term follow up.

Objective: To study the safety and efficacy of denervation of renal artery branches in the treatment of resistant hypertension.Methods: Sixty patients with resistant hypertension were enrolled. The patients were randomly assigned to the mainrenal artery plus branch ablation group or the main renal artery ablation group. The clinical data and operation-relatedparameters, including number of ablation points, temperature, and average energy, were recorded. Ambulatory bloodpressure were taken for all patients at the baseline and at 6 months after treatment. Office blood pressure was recordedbefore treatment and after treatment every 3 months for 2 years.Results: Sixty patients with resistant hypertension were enrolled in this study. There were 30 patients in each group.Angiography was performed after ablation. No renal artery complications, such as stenosis and dissection, occurredin the two groups. There was no significant difference in age, sex, BMI, comorbid disease, and medication betweenthe two groups (P > 0.05). The number of ablation points for the main renal artery plus branch ablation group wasgreater than that for the main renal artery ablation group. The office blood pressure and 24-hour blood pressure weresignificantly lower 6 months after treatment than before treatment in both groups (P < 0.05). Office blood pressure inthe main renal artery plus branch ablation group was lower than that in the main renal artery ablation group during the3–12-month follow-up period, with a statistical difference. However, as the follow-up time increased, the differencedisappeared.Conclusion: The results of this study show that main renal artery plus branch ablation is a safe interventional method,but there was no obvious advantage on long-term follow-up compared with only main renal artery ablation.

Resistant hypertension and chronic kidney disease are closely related from a pathogenetic and clinical point of view. To study the dynamics of functional state of kidneys and as well as to identify the predictors of its improvement, 117 patients with resistant hypertension were examined. Dynamic follow−up of patients included monitoring of antihypertensive therapy, blood pressure, biochemical and humoral parameters during 3, 6 and 36 months of treatment. The findings have shown that a significant long−term improvement in blood pressure control in the patients with chronic kidney disease improves their function and also has a nephroprotective effect in patients without any signs of renal damage. The established prognostic value of the higher initial creatinine content for the improvement of renal function in patients with resistant hypertension is stipulated with a positive effect of antihypertensive therapy on the glomerular filtration rate dynamics. The close association between improved renal function and lower baseline levels of interleukin 6 as well as an active renin in the blood may indicate a role for systemic inflammation and renin−angiotensin−aldosterone system activity in the renal dysfunction development. Prolonged improvement in blood pressure control in the patients with resistant hypertension without diabetes is associated with a stable level of urinary albumin excretion, whereas in patients with diabetes, an albuminuria increases over time. The study concluded that independent predictors of improved renal function in patients with resistant hypertension are higher baseline creatinine and lower glomerular filtration rate, lower concentrations of interleukin 6, active renin and plasma potassium. Key words: resistant arterial hypertension, chronic kidney disease, functional state of kidneys, antihypertensive therapy.
