Critical Stenoses in Brachiocephalic Hemodialysis Fistula Patient

Multiple critical stenotic lesions in a brachiocephalic hemodialysis fistula patient. Each of the three treatment sites was successfully treated at low PTA inflation pressure using a standard off-the-shelf balloon inside the XO Score.
