The drain was inserted into the patient and the physician aspirated.However, the physician noticed air in the syringe instead of fluid.The physician then reattempted to secure the lock and form the pigtail.Contrast was injected, but air remained in the syringe.The drain was removed and clamped halfway down the catheter, but it aspirated air again.Upon inspection of the tube, a slight pull was used and the hub separated from the catheter.The drain was replaced with a new device, and there were no injuries or additional procedures.
