Acute Upper Limb Ischemia in an Octogenarian with Chronic Atrial Fibrillation and Previous CABG: A Multidisciplinary Approach to Limb Salvage

An 86-year-old man with hypertension, dyslipidemia, multivessel coronary artery disease post coronary artery bypass graft (CABG), and chronic atrial fibrillation (AF) presented with acute numbness, weakness, and discomfort in his left arm. The left ulnar artery exhibited diminished blood flow during the examination. Ultrasound imaging showed an acute thrombus, and anticoagulation with heparin was initiated. A thrombectomy was performed, successfully removing the thrombus. Postoperative evaluation confirmed restored blood flow with no residual thrombus. The patient was discharged on warfarin. This case highlights the management of acute limb ischemia in atrial fibrillation and the importance of anticoagulation in preventing thromboembolic events.
