Iatrogenic Left Internal Mammary Artery Perforation Treated With a Covered Stent Via Transradial Approach (JACC Case Reports December 2019)
Inadvertent perforation of the left internal mammary artery during a blind approach to the subclavian vein for pacemaker or central venous catheter insertion is an emergency that requires immediate treatment. Covered stent deployment is a quick and effective treatment, especially in patients with hemodynamic instability. The procedure may be safely performed by using the radial approach.
