Vascular access monitoring & preservation

Predict potential thrombosis formation weeks in advance

Introduction to Vasc-Alert™

Vasc-Alert is a unique vascular access surveillance programme for hemodialysis patients that allows care providers the ability to detect and respond to potential access complications before they arise. The programme works by analyzing treatment data to derive the intra-access pressure at the arterial and venous needle sites. When the pressure trend increases, it is an indication that stenosis may be growing. Weekly reports alert staff to possible issues allowing for quick evaluation and invention. Studies have shown that the early detection of vascular access stenotic lesions, followed by timely corrective procedures, reduces the thrombosis rate and prolongs access survival1. It is widely held that monitoring for an elevation in venous line pressure, which increases as a stenosis develops, would have clear diagnostic value2.

Vasc-Alert's approach conveys many benefits. First, no personnel need to administer the test, saving staff time. A test is performed with each treatment, rather than just once a month. And since Vasc-Alert is looking at pressure and not blood flow, it can detect the growth of stenosis earlier so that intervention can take place before the stenosis gets too advanced.
