Management of Inadvertent Arterial Catheterization during Central Venous Catheter Placement: A Case Series.

Percutaneous central venous catheterization, although a widely used technique in ICU patients worldwide, is not devoid of complications even under real-time ultrasound guidance. Arterial puncture is a well-recognized complication, while unintended subclavian or carotid artery cannulations during attempted central venous catheterization are infrequent, but documented complications with potentially deleterious consequences. Recently, endovascular balloon tamponade has emerged as the preferred initial approach to repair inadvertent arterial cannulations. Herein, we present a case series of inadvertent arterial catheterization during an attempted ultrasound-guided access of the right internal jugular and the left subclavian vein that were successfully managed with endovascular balloon tamponade.
