Spontaneous aortic thrombosis is exceedingly rare, and optimal treatment remains uncertain. We present an unusual case of a spontaneous aortic thrombus at the renal artery level in a patient undergoing active cisplatin treatment for urothelial carcinoma. Management included catheter-directed thrombolysis followed by thrombectomy. An open cutdown was performed on the left common femoral artery (CFA), with right groin access via a 6-Fr sheath. Clamping of the left superficial and deep femoral arteries, along with balloon occlusion of the right common iliac artery, prevented distal embolization. A Coda balloon introduced via direct left CFA puncture with a 20-Fr sheath was positioned above the aortic thrombus. After inflation, clots were trawled to the sheath, "sandwiching" the clots before removal of the balloon and sheath via the left groin. Post-operatively, the patient recovered well and received continued therapeutic anticoagulation.
