Surgical treatment of renovascular hypertension in children

Abstract

In fourteen children with renovascular hypertension the most prevalent lesion was fibromuscular dysplasia (nine patients). Nephrectomy was performed in four patients prior to the adoption of reconstructive vascular techniques. Revascularization of a variety of lesions was employed with autogenous arterial grafts, which gave excellent results over a long follow-up period in ten patients. Ex vivo microvascular repair was used in one patient rather than nephrectomy for management of branch artery lesions. These results indicate that careful and precise arterial repairs will yield a high cure rate in children with renovascular hypertension without the sacrifice of renal parenchyma.
