Why Measure Flow during Angioplasty?
Intra-access flow measurements during angioplasty are necessary because intra-access blood flow fails to normalize after angioplasty in 20 – 30% of patients.1 The innovative HVT100 Endovascular Flowmeter and ReoCath™ Flow Catheter allow you as interventional radiologists to obtain, for the first time, quantitative information about vascular access functionality and angioplasty success during the procedure. Designed specifically for the interventional radiology suite, the HVT100 system measures access flow (ml/min) in AV fistulas and grafts. Test results are objective and reproducible.
Improve Angioplasty Success
Transonic endovascular flow measurments during the intervention let you know immediately when you have corrected a flow-limiting stenosis. You will avoid prolonging the intervention unnecessarily. Nor will you have to wait for the dialysis clinic to check the efficacy of your intervention. After angioplasty, if blood flow is still < 600 ml/min for a prosthetic graft or < 500 ml/min for a fistula, one or more additional stenoses might be present. The data prompt you to further explore and make additional adjustments to “repair” the graft while the patient is still in the IR suite. Flow verification during the intervention averts a patient’s immediate return to the IR suite for a re-intervention.
