Endovascular Stent Graft Repair of Left Renal Artery Pseudoaneurysm From Malignant Fibrous Histiosarcoma

A renal artery pseudoaneurysm is a rare but life-threatening complication. Historically, these vascular abnormalities have been treated using open surgery, but today’s endovascular techniques provide less invasive forms of treatment. Though literature supports selective angio-embolization as an effective form of repair, there are little data on covered stent placement for renal artery psuedoaneurysms. The authors report a case of left renal artery pseudoaneurysm repaired with a covered stent that allowed a patient with malignant fibrous histiosarcoma to receive chemotherapy with minimal risk of rupture.
