Spontaneous Renal Artery Pseudoaneurysm Treated By Arterial Embolization

Abstract

Renal artery pseudoaneurysm is a rare vascular lesion. It is found with increasing frequency as a result of unrelated abdominal imaging or on work-up for hypertension. The pseudoaneurysm can be defined as a pulsatile hematoma that communicates with the artery through a small hole in the arterial wall. However, the rupture of pseudoaneurysmis the most dreaded complication because it causes death. There are many causes of renal artery pseudoaneurysm and are generally related to renal biopsy, nephrectomy or percutaneous procedures. In addition, there is a relationship with penetrating traumas and, more rarely, with blunt traumas. We report a case of renal artery pseudoaneurysm treated successfully with vascular plug embolization. A 22-year-old woman with hypertension presented with an incidental left renal artery pseudoaneurysm measuring 35x23 mm. We successfully performed endovascular treatment with vascular plug embolization without any complications.
