Acute left arm ischemia associated with floating thrombus in the proximal descending aorta: combined endovascular and surgical therapy.

Free floating thrombus in the proximal descending aorta is an uncommon and dangerous condition that can be associated with acute peripheral embolization. The few cases described were solved with surgical and/or medical therapy. We report the case of a patient with acute left arm ischemia secondary to the presence of floating thrombus in the proximal descending aorta extending into the left subclavian artery, solved with combined endovascular and surgical therapy. Treatment was successfully performed with thrombembolectomy combined with temporary deployment, into the descending aorta, of a Wallstent in a "basket-fashion" to avoid distal embolization secondary to thrombus fragmentation. At 1 year follow-up the patient remained symptom-free.
