Patient had an abdominal aortic aneurysms (aaa) procedure with an aorta-uni stent graft and double chimney stent.At the target location, the physician re-inflated the stent.During this inflation, the stent would not attain nominal pressure.During removal, the balloon did not deflate and could not be removed and the hub separated from the shaft.As it was removed it was discovered that the lunderquist wire also traveled into the arm with the stent delivery system.Once the lunderquist wire was retracted into the aorta, the stent delivery system was finally removed.Upon inspection it was discovered that the balloon was bunched to one end of the catheter.A balloon was then inflated in the vessel to ensure that the stent was fully inflated.The patient's left arm developed a stenosis and dissection (tear) which required a brachial cut down and bare metal stent placement to handle the dissection.
