ProGlide entrapment of the occlusive balloon during repair of an iatrogenic subclavian artery injury.

The insertion of any central venous catheter (CVC) is associated with a risk of damage to neurovascular structures, pneumothorax, cardiac arrhythmias, and infection. Unintentional arterial puncture remains rare, occurring in 6.3-9.4% of attempted internal jugular vein (IJV) catheterisation and 3.1-4.9% of attempted subclavian vein catheterisation. We present a previously undocumented complication encountered while utilising the Perclose ProGlide device in the case of a 59-year-old male who underwent right subclavian artery closure following the accidental insertion of a 14Fr Vascath into the right subclavian artery. This was performed using two ProGlide devices and one Angio-Seal device. Following deployment of the ProGlide devices, an uninflated balloon passed into the subclavian artery as a precaution, but not used, was removed. One of the ProGlide devices became dislodged having been deployed into the balloon, threatening haemostasis.
