[Spontaneous recanalization after embolization of the renal artery with an Amplatzer vascular plug 4]. / Recanalización espontánea tras la embolización de una arteria renal con un tapón vascular Amplatzer tipo 4.

The Amplatzer vascular plug (AVP) is an occluding device used in vascular embolizations. Thanks to its excellent maneuverability and effectiveness, it is being used more and more often. The latest version, the AVP 4, enables access to smaller and more tortuous vessels. To date, the only cases of spontaneous recanalization published occurred with earlier versions of the AVP. We present a case of recanalization after renal artery embolization with an AVP 4.
