Re: 'evaluating patency rates of an ultralow-porosity expanded polytetrafluoroethylene-covered stent in the treatment of venous stenosis in arteriovenous dialysis circuits'

摘要

The recent report by Chan et al (1) describes the first use of nonporous VIABIL stent-grafts (W.L. Gore and Associates, Flagstaff, Arizona) in hemodialysis arterio-venous (AV) access circuits. Although novel, their results should be taken with great caution.
