Aorto-Renal Dysplasia in Childhood: The Overlap of Neurofibromatosis Type 1 and Pediatric Renovascular Hypertension.

PURPOSE OF REVIEW: This narrative review aims to summarize what is currently understood about Neurofibromatosis Type 1 (NF-1) and renovascular hypertension (RVH) in children, including clinical presentation and diagnosis, epidemiology, genetics, and management considerations including advances in treatment modalities. RECENT FINDINGS: Most of what is currently understood about NF-1 and arterial dysplasia leading to RVH relies on the inclusion of patients with NF-1 in single-institution reports. The management of pediatric RVH often requires multi-modal therapies inclusive of anti-hypertensive medications and revascularization for refractory cases, through catheter-based (i.e., endovascular) and open surgical means. There is a need to develop genotype-targeted guidelines for the diagnosis and management of pediatric aorto-renal dysplasia resulting in RVH in patients with NF-1. SUMMARY: While our understanding of pediatric RVH and NF-1 has evolved over the past decade, critical research questions have emerged that encompass epidemiology, etiology and genetics. These research questions require immediate attention to establish and optimize standardized diagnostic and treatment guidelines.
