Novel Approach to Managing Inadvertent Arterial Placement of Central Venous Catheters: Report of Two Cases and Review of the Literature

Recently, there has been an increase in the frequency of central venous catheter insertions in multiple medical specialties. This increase has been accompanied by a higher incidence of complications, such as arterial puncture or subsequent catheter insertion. Arterial injuries resulting from inadvertent central venous catheter insertion have traditionally been managed with manual compression or open surgery. When traditional treatment methods are limited, they are supplemented with endovascular therapies such as vascular closure devices or balloon catheters. However, there are instances in which the application of these endovascular therapies is not feasible. Therefore, we aimed to present two cases in which the combination of temporary balloon tamponade and plug-based tract embolization resulted in effective treatment outcomes when conventional endovascular therapies were limited.
