Inadvertent catheterization of arterial system during placement of a central venous catheter is a rare, how- ever, potentially severe complication. Puncture of arteria subclavia within cannulation of subclavian vein can occur due to anatomical relation of both vessels.
We report a case, where the iatrogenic injury of the artery was resolved by an endovascular closure device Angio-Seal, which reaches hemostasis by a mechanical method, supplemented with coagulation attributes of collagen. In experienced hands, it seems to be a solid alternative to an invasive surgical solution and it could be a life support method.
