Endovascular Salvage of a Ruptured Renal Pseudoaneurysm-A Case Report

ObjectivesIn recent years, the widespread use of vascular imaging and increased workups for atherosclerotic disease have led to more frequent detection. Although the true incidence remains unclear, the number of renal artery aneurysms identified through imaging has increased. Ruptured renal aneurysms are extremely rare and can be life-threatening without emergency treatment. However, only a few studies have focused on its treatment. In this report, we present a case of a ruptured renal pseudoaneurysm treated with endovascular therapy.Case DescriptionA female patient who had previously undergone surgery for a ruptured abdominal aortic aneurysm (rAAA) presented with progressive left-sided lower back pain. Computed tomography revealed a ruptured left renal pseudoaneurysm near the AAA replacement. Chimney endovascular aneurysm repair (Ch-EVAR) was performed immediately. Completion angiography demonstrated no endoleak and preserved flow into the left renal artery. The patient was discharged 4 days post-Ch-EVAR.ConclusionsThis case offers valuable perspectives on managing ruptured renal aneurysms. Ch-EVAR represents a feasible treatment option for such cases. Following treatment for aortic emergencies such as rAAA, careful long-term follow-up is necessary.
