title: Improved results of vascular reconstruction in pediatric and young adult patients with renovascular hypertension.
abstract: From 1955 to 1988, 56 patients 21 years old or younger underwent surgical treatment for renovascular hypertension at our clinic. The cause of renal artery disease was fibrous dysplasia in 53 patients, Takayasu's arteritis in 2 or an arterial aneurysm in 1. Bilateral or branch renal artery disease, and extrarenal arterial disease were present in 16, 23 and 11 patients, respectively. The results of 28 patients treated from 1955 to 1977 (group 1) were compared to those of 28 patients treated from 1978 to 1988 (group 2). Hypertension was cured or improved postoperatively in 83% of the patients from group 1 and in 96% from group 2 (p = 0.07). However, this outcome was achieved through surgical revascularization in only 48% of the patients from group 1 compared to 96% from group 2 (p = 0.0002). A multivariate analysis revealed that the only significant variable related to clinical outcome was the era of treatment, which reflects the improved technical efficacy of revascularization during the last decade. Aortorenal bypass and renal autotransplantation have emerged as the preferred revascularization operations. It currently is possible to achieve amelioration of hypertension and preservation of renal function in most young patients with renal artery disease.
