Renovascular Hypertension with Renal Artery Intervention in Children

Abstract

Background: Secondary hypertension is more common in children than in adults. Although the number of patients with renal artery stenosis is relatively small, renal artery stenosis is an important clinical condition because of the potential for a complete cure.
Methods: We reviewed the clinical outcomes of patients with renovascular hypertension who underwent percutaneous transluminal angioplasty or surgery at a single center between 2005 and 2011. The hypertensive response was defined as （1）cured： normal blood pressure with no antihypertensive treatment, （2）improved： improved blood pressure with identical or reduced treatment, （3）unchanged： no change in blood pressure despite angiographic success, or （4）failed.
Results: The first surgical or endovascular intervention was performed between 1.8 and 13 years of age. Nineteen renal angioplasty procedures and four surgeries were done. The outcomes were as follows： cured in one patient who underwent surgery, improved in 14 patients who underwent renal angioplasty and three who underwent surgery, unchanged in four patients who underwent renal angioplasty, and failed in one patient who underwent renal angioplasty.
Conclusions: The results as a whole were satisfactory. The treatment of small children and patients with double renal arteries is difficult because of their small vessels.
