Please do NOT include any actual patient medical records with your question. Patient came in status post endovascular repair of left arm AV fistula pseudoaneurysm usign a viabhan stent graft. The patient has developed an AV fistula complication consistent with stenosis. Fistula cannulated and fistulogram obtained. Stenosis noted in cephalic vein and two pseduoaneurysms noted.PTA was performed on cephalic vien. Attention was turned to the pseudoaneurysms. The pseudoaneurysm clsoer to the elbow appreared to be large. Due to the size of teh pseudoaneurysm, the decision was made to proceed with incision, the pseudoaneurysm was exposed. A pseudoaneurysm was then opened under direct vision. Approximately 20ml of old organized thrombes was evacuated. The pseudoaneurysm was then reparied primarily using prolene suture. not sure what to code for the driange of pseudoaneurysm? Please advice. Thanks
