Endovascular coiling of an internal mammary artery pseudoaneurysm following placement of an internal jugular central venous catheter.

We discuss an interesting case of a right internal mammary artery pseudoaneurysm discovered after an attempted right internal jugular venous catheter placement. Such injury to the internal mammary artery is a rare complication of traumatic injuries to the chest, sternotomies, and central venous catheter placements. It has been reported after subclavian line placements, but not after an internal jugular catheterization.
