RESUMO
A 61-year-old female was admitted to our hospital complaining of paresthesia, pain, and intermittent weakness in the right hand. A pulsating mass with bruits had developed on the patient's upper arm. We also noted an absence of radial artery pulsation. The angiographic findings revealed a classic "string of beads" appearance, which involved both brachial and renal arteries. The right brachial artery exhibited an aneurysm, which was filled with thrombus, and the distal radial artery was occluded with thromboemboli. We excised the abnormal brachial artery segment, replacing it with an autogenous reversed saphenous vein conduit. Consecutive thrombolytic therapy was then performed for the treatment of the radial artery embolism. Histological examination revealed that the patient was suffering from medial fibromuscular dysplasia. This uncommon form of fibromuscular dysplasia, which involves both brachial arteries with embolization, can be efficiently treated via surgery and consecutive thrombolytic therapy.
