Delayed Endovascular Treatment of Renal Artery Dissection and Reno-Vascular Hypertension after Blunt Abdominal Trauma

Abstract

As a rare complication of blunt abdominal trauma, dissection of the renal arteries can be observed among other severe complications [1, 2] and necessitates immediate surgical or endovascular intervention to prevent significant ischemic organ damage. If successful intervention cannot be performed immediately, patients are prone to develop renovascular hypertension over time through the activation of the renin-angiotensin-aldosterone system (RAAS). However, they still may benefit from a delayed surgical reconstruction of the vessel or percutaneous endovascular treatment. If recovery of kidney function and reversal of renovascular hypertension before the intervention is in doubt due to prolonged delay of revascularization, percutaneous endovascular treatment may be the first option because complication rates can be kept reasonably low. We report a case of a successful but delayed endovascular treatment of a traumatic renal artery dissection and reversal of consecutive renovascular hypertension after blunt abdominal trauma.
