Endovascular treatment of an innominate artery iatrogenic pseudoaneurysm following subclavian vein catheterization.

Central venous catheterization is routinely required in a wide range of clinical situations such as hemodynamic monitoring, delivery of blood products and drugs, hemodialysis, total parental nutrition, and management of perioperative fluids. Pseudoaneurysms account for 4% of all innominate artery aneurysms. Clinical presentation may include airway and neurological compression, chest pain, mediastinal syndrome, upper limb ischemia, and hemodynamic instability. We report what we believe is the first documented case of a successful endovascular stent-graft repair of an innominate artery iatrogenic pseudoaneurysm.
