Huge right subclavian artery aneurysm due to inadvertent trauma during percutaneous central venous catheter insertion

Central venous access is a common procedure performed in many clinical settings for a variety of indications. Central lines are not without risk and there are many complications associated with its placement. Complications can present in an immediate or delayed fashion and vary based on type of central venous access. Significant morbidity and mortality can result from complications. These complications can cause a significant healthcare burden in cost, hospital days, and patient quality of life. Advances in imaging, access technique, and medical devices have reduced and altered the types of complications encountered in clinical practice, but most complications still center around vascular injury, infection, and misplacement. Recognition and management of central line complications are important but prevention is the ultimate goal. Here, we discuss a rare complication associated with central venous access causing subclavian artery aneurysm.
