Shin, Yun, and Park: Congenital Renal Arteriovenous Malformation in Pregnancy

Abstract

Congenital arteriovenous malformation of the kidney is a rare condition and there have been few reported cases that were detected during pregnancy because of a fistula. Of the 7 such cases in the literature, either a nephrectomy or partial nephrectomy was done during pregnancy, or an abortion was induced. We report here on a case of arteriovenous malformation that was treated successfully by therapeutic embolization. The patient's convalescence was unremarkable and a healthy newborn was delivered without any complications.
