PTRA for the left stenotic venous bypass graft. a. Angiography before PTRA. We used a guiding catheter which shape of the tip was relatively straight (arrowhead). There were two sites of stenosis at the left renal bypass graft (arrow). b. Angiography after stenting. The mounted balloon could not achieve adequate dilation (arrow). c. Angiography after additional dilation. Stenotic lesions were adequately dilated (arrow). We used double wire technique to insert the additional dilator (arrowhead).
