The 10 x 40 mm vaccess angioplasty balloon (bard incorporated) tore during 3rd inflation at 8 atm while treating three venous stenosis that had been previously stented.No inflation exceeded rated burst pressure of 15 atm.Balloon tore circumferentially, rather than longitudinally, so its central half could not be removed via 6 fr sheath, or via the access with sheath removed.Central half of balloon crumpled against fistula wall with traction on the catheter.Via two new accesses occlusive balloons were placed to isolated fractured balloon from blood stream and prevent emboliation.Initial access was enlarged and after it detached from catheter body, balloon fragment still attached to catheter tip was extracted with forceps.Surgical wound closed with dissolvable suture.Stenoses successfully treated angiographically.Fistula patent immediately following procedure.
