We report the first successful application of nonferromagnetic embolization coils for endovascular exclusion of a mycotic right subclavian artery aneurysm. A 58-year-old woman presented with acute cervical pain and a pulsatile mass in the right supraclavicular fossa under antibiotic medication for subacute infectious endocarditis. Diagnostic work-up including duplex sonography, digital subtraction angiography, and magnetic resonance imaging demonstrated a saccular aneurysm of the extrathoracic right subclavian artery. As an alternative to open surgery or stent-graft repair, this pathology was electively treated by transcatheter coil embolization. No neurological deficit or ischemic symptoms were noted during 9 months clinical follow-up. Multislice computed tomography scan revealed complete occlusion of the mycotic aneurysm 6 months after the interventional procedure. Transcatheter closure with Inconel embolization coils is a cost-effective and safe therapeutic option in patients with mycotic aneurysm originating from the subclavian artery.
