“…This concern was also expressed in other study (23). Restenosis, accounting for poor blood pressure control, was detected in nine of 22 patients (40.9%) in this study, giving a prevalence similar to that reported in a previous study (35%, n=20) (16). Neointima formation and recoil of immature renal arteries are responsible for restenosis (21).…”

“…However, 27.3% (6/22) of children with renovascular hypertension failed to respond to PTRA. The success rate of PTRA for pediatric renovascular hypertension varies from 48.5% to 100% (8,16,17). The outcome of PTRA may be influenced by many factors, such as patient age, etiology, distribution of lesions, length and severity of lesions, and impairment degree of the target organ.…”

ORIGINAL ARTICLE PURPOSE We aimed to evaluate the long-term outcome and efficacy of percutaneous transluminal renal angioplasty (PTRA) for pediatric renal artery stenosis (RAS), which is an important cause of medication-refractory pediatric hypertension. MATERIALS AND METHODSWe retrospectively evaluated 22 hypertensive children (age range, 3-17 years) who underwent PTRA from February 2000 to July 2012. Sixteen patients had Takayasu arteritis and six fibromuscular dysplasia. Five were not included in the statistical analysis due to loss to follow-up. RESULTSTechnical success was achieved in 32 of 34 procedures (94.1%). The stenosis rate decreased from 84.5% before PTRA to 20.1% after PTRA. Treatment was effective in 72.7% (16/22) of patients, including complete cure in 27.3% (6/22) and improvement in 45.5% (10/22). Systolic and diastolic blood pressures decreased from 153±19.1 to 131.7±21.4 mmHg and from 97.9±14.2 to 83.6±19.3 mmHg, respectively (P < 0.01). Number of antihypertensive agents decreased from 2.7 to 0.5 per patient. Restenosis was detected in 40.9% (9/22) of patients, with a restenotic interval of 11.8 months (range, 3-47 months). Lesion length was strongly correlated with clinical success (cure and improvement) (independent-sample t test, P < 0.001; binary logistic regression, P = 0.040). CONCLUSIONLesion length is an important determination of clinical success with PTRA for pediatric RAS. PTRA is an appropriate treatment option for pediatric renovascular hypertension due to Takayasu arteritis and fibromuscular dysplasia.

“…Bayrak et al 19 from Turkey reported their experience of using PTA in 20 children with RAS, with a success rate of 100%. The underlying aetiologies in their children were Takayasu arteritis in 12, FMD in 5 and NF1 in 3 cases.…”

“…16,17 Surgical reconstruction or endovascular therapy With a high initial success rate, endovascular procedures seem attractive for TARAS. 18,19 However, although encouraging midterm to long-term results have been reported sporadically, 20,21 most believe that the restenosis after angioplasty or stenting is common. Bayrak et al 19 performed PTA in 12 TARAS patients with a technical success rate of 100%, but restenosis was observed in five patients during 55.7 months of follow-up.…”
