It was reported the balloon failed to deflate and a portion was left in the patient.A ranger 7.0 mm x 40 mm, 80 cm over the wire (otw) drug coated balloon (dcb) was being used for an avf angioplasty procedure.The ranger balloon 7x40mm was used to dilate the previously stented vessel at 14atm and deflated successfully.Then a mustang 8x40mm was used to post dilate the vessels.The physician decided to reuse the ranger 7x40mm balloon.After inflating the ranger balloon 3 more times, the balloon was unable to deflate despite 2 to 4 attempts.The physician used a micro-puncture needle to prick the balloon externally to remove the ranger balloon from the vessel, but 1/3 of the balloon was missing.A computed tomography (ct) and ct pulmonary angiogram (ctpa) scan were performed but the missing piece was not found.The physician believed that it's too small to be detected and does not cause harm to the patient as she is stable.The sheath and balloon hub were dissected to check for the remnant but nothing was found.Facility staff measured the balloon with a brand new 40mm ranger balloon, and only 2-3mm was missing.Follow up with surgeon 1-day post-op, patient is well and stable.
