“Having the ability to measure flows has allowed me to better know what I’m doing with my flow reductions, my venous angioplasty and imaging and whether or not I am actually making a difference.” Gregg Miller, Chief Medical Officer, Vascular Access Care

When flow in AV fistulas or grafts falls below a critical threshold, percutaneous transluminal angioplasty (PTA) is the front line treatment for repairing an access. Elective rather than emergent, less invasive than surgery, angioplasty conserves the current access site and preserves future sites. During angioplasty, the ReoCath® Flow Catheter and HVT100 Endovascular Flowmeter provides on-the-spot, intragraft feedback about the functionality of the entire vascular access circuit. 

The measurements tell the interventionalist at the outset if angioplasty is actually necessary or whether flow is sufficient to delay the intervention for a future date. Secondly, during an intervention, intragraft flow measurements provide objective functional data to guide the interventionalist in achieving the target flow goal. Finally, at the end of the intervention, measuring flow can determine whether there has been elastic recoil of the vessel. 

Flows can be documented for the patient record and compared with vascular access flows obtained during subsequent hemodialysis.
