During a procedure to improve the flow of the pt's arterial venous fistula, the dr performed angioplasty of the cephalic arch and noted there was extravasation of the contrast.The dr proceeded to place a viabahn 8 x 10 covered stent.After deployment the delivery system of the stent became lodged within the stent and could not be removed.It appeared the stent did not fully expand.The pt's blood pressure and pain levels were increased and the blood pressure could not be medically controlled; therefore, the decision was made to transfer the pt to the hosp via ems.The transferring physician spoke with the radiologist at the hosp who advised that although he tried to expand the stent with a high pressure balloon, he was also unsuccessful in removing the delivery system because the stent would not expand.The delivery system was ultimately removed surgically be a vascular surgeon.The surgeon that performed the procedure advised the transferring physician that he was able to remove the delivery system but decided to leave the stent in place for safety purposes.The pt's avf access was ultimately ligated and plans for a creation of a new fistula are forthcoming.
