Arteriovenous dialysis grafts are the most commonly implanted prosthetic grafts. Thrombectomy with selective graft revision is traditional therapy for occlusions, but patency is minimally prolonged. Stenoses are determined by tactile feedback from an embolectomy catheter and lack of prograde and retrograde bleeding. An objective method for studying the graft and inflow and outflow tracts that permits appropriate endoluminal or surgical correction is described. This approach is appealing because: (i) the current approach is inadequate; (ii) it offers an objective, quantitative method to determine frequency and severity of critical stenoses within the failed access graft; (iii) remote and perigraft stenoses can be treated at the same setting; and (iv) it promotes the development of endovascular skills by surgeons in a high-volume, low- risk setting.
