Entrapment of fractured balloon after angioplasty in an AV access using a covered stent

Fracture of the angioplasty balloon is a known complication during endovascular procedures in arteriovenous (AV) fistulas and grafts. We describe a case of a patient with end-stage renal disease (ESRD) on dialysis with a brachiocephalic AV fistula that had become dysfunctional. After a percutaneous angioplasty procedure during balloon withdrawal, a portion of the balloon fractured and separated due to the balloon being caught in the struts of a previously placed bare metal stent. A covered stent was used to contain the segment of the fractured balloon to the wall of the fistula. The use of a covered stent in jailing the fractured balloon to prevent further complications is not well described. This strategy may be implemented in some circumstances such as this case to avoid surgical interventions.
