title: Congenital renal arteriovenous malformation in pregnancy presenting with hypertension.
abstract: Congenital renal arteriovenous malformations (AVMs) are rare, with approximately 50 cases reported in the literature. Typically, they are small (1 to 2 cm) and the majority present with hematuria and symptoms and signs of congestive heart failure. Review of the literature revealed only 4 cases reported in pregnant patients and their presentation was with hematuria and rupture of the AVM. We present a case of a young female patient with a 6 cm congenital renal AVM who was otherwise asymptomatic until her first pregnancy, when she developed and presented with symptoms of hypertension and an abdominal bruit. Her symptoms persisted postpartum. Hematuria and rupture of the AVMs were not part of her clinical course. A partial nephrectomy was curative.
