Ultrasound-guided percutaneous angioplasty of the chronically occluded arteriovenous fistula (AVF) for hemodialysis. a Blood flow in the brachial artery. b Ultrasound image of the radial artery. c No blood flow in the totally occluded AVF before intervention. d Schematic of the occluded AVF. e A 6-Fr sheath was retrogradely inserted into the fistulous vein. f A guidewire failed to cross the chronic total occlusion lesion. Arrow shows the curved tip of the wire. g The guidewire crossed the lesions with the support of a 6-Fr angiographic catheter. Arrow shows the tip of the wire. The radial artery (h) and AVF (i) was dilated with a balloon. j The AVF after balloon dilation
