Patent vascular access is critical for @entity1 on regular hemodialysis. Prosthetic grafts are good alternatives when the superficial venous system is of poor quality. However, @entity715 is one of the main drawbacks of synthetic grafts, with reports of 59% to 90% patency rates for 1 year. In cases of @entity715 of prosthetic arteriovenous fistula grafts, percutaneous mechanical thrombectomy has recently gained clinical popularity as a potential alternative to surgical thrombectomy or pharmacologic thrombolysis. We reviewed our preliminary results from 30 percutaneous rotational thrombectomies performed in a total of 22 @entity1 in the setting of acute dialysis-access prosthetic graft occlusion of the upper extremity. Among the 30 cases of acute occlusion of the arteriovenous graft, immediate success with angiographic flow restoration was observed in all @entity1 except for 2 @entity1 (both females; 6%), with de novo occlusion where reocclusion occurred within 12 hours despite apparent immediate angiographic patency. The mean duration between the initial presentation with acute arteriovenous graft occlusion and the thrombectomy procedure was 27.4    12.4 hours. The mean duration of graft patency was 10.45    0.6 months. A total of 75% of the arteriovenous grafts were patent at the end of 12 months of follow-up. Female gender, @entity6 , and diagnosis to intervention interval were reviewed for midterm graft failure, and the presence of @entity6 yielded significance (P < 0.05). Percutaneous techniques play important roles in the treatment of failed or failing arteriovenous fistulae and grafts. Ongoing analysis of outcomes of both percutaneous and surgical intervention is necessary to continue to identify optimum treatment algorithms.
