Intravascular Therapy for Bilateral Renal Aneurysms in a Hemodialysis Patient: Renal Artery Embolization with Stent Graft Therapy (Pincer Exclusion Technique)

Abstract

With recent progress and advancements in devices and techniques, endovascular therapy is now being frequently used for high-risk patients. We experienced case of a bilateral renal artery aneurysm in a 55-year-old male patient undergoing hemodialysis for renal failure. Computed tomography (CT) revealed left and right renal artery aneurysms with dilatations of 51 and 13 mm in diameter, respectively. Because of several comorbidities, such as renal failure and systemic lupus erythematosus (SLE), renal artery embolization with stent graft therapy (Pincer Exclusion Technique) was chosen. The postoperative CT showed no endoleaks, and the patient was discharged 10 days after the operation. Overall, this case suggests that the total occlusion of bilateral renal artery is feasible and effective when the patient is under hemodialysis for renal dysfunction. Furthermore, this is the first reported case for successful treatment of a bilateral renal artery occlusion in a patient undergoing hemodialysis for renal failure.
