title: Inadvertent subclavian artery catheter placement complicated by stroke: endovascular management and review.
abstract: BACKGROUND
  Removal of large-bore venous catheters misplaced within the subclavian artery risks significant hemorrhage due to the noncompressible entry site. Comorbidities in these patients often make traditional surgical approaches prohibitive.
  
  
  METHODS
  We present a case of inadvertent subclavian artery placement of a central venous catheter complicated by thromboembolic stroke, illustrate treatment with a combination of percutaneous closure and temporary balloon tamponade, and review the endovascular management of this unusual problem.
  
  
  CONCLUSIONS
  Endovascular treatment of inadvertent subclavian artery catheterization appears to be a reasonable option, and its less-invasive nature may be beneficial for patients in whom the underlying disease initially required central venous access.
