Renal cell carcinoma as a cause of aortic tumor thrombus embolization and acute limb ischemia

Abstract

This article presents a unique case of acute limb ischemia resulting from arterial tumor embolism secondary to renal cell carcinoma involving an aortobi-iliac bypass graft. To the best of our knowledge, this instance is the first documented in the literature of such a complication. The patient, a man in his 70s with a complex medical history, underwent bilateral femoral embolectomy and subsequent endovascular intervention for the resolution of the tumor thrombus. The rarity of this phenomenon poses challenges in formulating a standardized management strategy.
