Retroperitoneal hematoma due to late perforation of aortic wall endograft deployment is a rare but, potentially, fatal event. We report a case of symptomatic retroperitoneal hematoma due to aortic perforation by free flow barbs of Ovation Prime stent graft. The patient was successfully treated by celiac trunk embolization and aortic cuff placement. The patient was discharged with no further treatment. At 3-month follow-up, no complications were detected.
