It was reported that the procedure was to treat a left femoral arteriovenous (av) graft.An 8x80mm armada 35 and 7x40mm armada 35 balloon dilatation catheter (bdc) were being used in the procedure and advanced separately to the av graft.Both balloons were inflated two to three times each, to 13 atmospheres (atm) when the balloons ruptured.In an attempt to pull the balloons back into the sheath for removal, a separation occurred.Some of the balloon pieces were removed from the anatomy with endoscopic forceps.The patient¿s entire anatomy was x-rayed to try to find the remaining broken portion of the balloon, but it was unable to be found.The patient came back to the operating room on the (b)(6) 2021; however, the outcome from that procedure is unknown.It was noted that ¿it is less likely that the balloons ruptured, but instead were snagged on stents that were already in place in the patient¿s leg¿.No additional information was provided.
