It was reported that the balloon failed to deflate and detached.Vascular access was gained via ipsilateral antegrade using ultrasound scan (uss) and ii-guided access.The target lesion was located in the common femoral artery (cfa).A 4x200mm, 150cm ranger balloon was selected an angioplasty procedure to treat critical limb ishemia.The balloon was inflated once to the maximum recommended pressure.The physician pressed the inflator button to deflate the balloon and the balloon initially appeared to be deflated; however, the balloon was partially inflated and was difficult to remove from the non-boston scientific 5f sheath.It was noted that the vacuum was removed during withdrawal.The balloon was pulled harder and got stuck in the sheath with a section of the balloon outside of the body and the remainder of the balloon was still within the patient.The balloon was pulled until it came out of the patient.It was then noticed that a 10mm segment of the balloon was missing.The missing balloon segment was unable to be located using x-ray imaging, and both duplex and ct angiogram.The procedure was partially completed as the physician was unable to do any completion angios since the sheath had to be removed.No further action was taken.There were no patient complications and the patients status was perfect post procedure.
