Abstract/OtherAbstract:
This report summarizes a feasibility study of transluminally placed endovascular grafts (TPEG) using pre-expanded polytetrafluoroethylene (PTFE) to treat venous abnormalities in patients on hemodialysis. Seventeen patients with peripheral (n = 11) or central (n = 6) venous lesions were treated with TPEG devices. Covered Gianturco stents were used for the peripheral lesions and covered Palmaz stents were used for central lesions. Venous abnormalities included vascular rupture after balloon angioplasty or surgical thrombectomy (n = 4), stenosis associated with an aneurysm (n = 2) and occlusive disease and central stenoses not responsive to balloon angioplasty (n = 11). The mean primary patency period was 37 days. The mean secondary patency period was 215 days. At 60, 180, and 360 days the primary and secondary patency rates were 40%, 32%, and 32%, and 70%, 55%, and 39%, respectively. Follow-up studies have shown various outcomes of the implanted TPEG devices, which have included stenoses within the TPEG (n = 2), stenoses central to the TPEG (n = 1), stenoses peripheral to the TPEG (n = 3), acute thrombosis extending to the TPEG without a stenosis (n = 1), graft abandoned with patent TPEG (n = 6), and TPEG patent within primary patency period at last follow-up (n = 4). The TPEG devices, made with pre-expanded PTFE, appear safe in the short term, do not prevent progressive dialysis access site failure, and need to be compared to PTA and endovascular stenting in a randomized prospective trial.
