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.

  Fig. 1. Right renal color Doppler study shows arterialization of the renal vein (white arrow). A waveform from the main renal vein demonstrates pulsatile flow, which is diagnostic of an arteriovenous fistula.

  Fig. 2. The upper pole of the kidney with a tortuous, serpiginous appearance of a cirsoid arteriovenous malformation, as seen on selective renal arteriography.

• 

  Fig. 3. The post-embolization film shows disappearance of the arteriovenous malformation.
