An isolated traumatic renal artery pseudoaneurysm treated by renal artery stent insertion: a case report presenting a nephron-sparing approach

Penetrating or blunt traumas can rarely lead to renal artery pseudoaneurysms (RAPs). Renal parenchymal lacerations usually accompany them, and nephrectomy is performed in these cases. Although angioembolization of the renal artery can negate the need for nephrectomy while treating the RAP, it is not a nephron-sparing procedure. Herein, we present a case of isolated (i.e. without accompanying renal laceration) left RAP. During conservative follow-up, the RAP enlarged, and subsequently, it was treated by renal artery stent insertion. An expandable covered stent was used during this procedure. The renal function was preserved without experiencing any complications.
