Why Quantitative Flow Measurement?
Visual assessments and flow velocity alone don’t always tell the full story. That’s why intraoperative flow measurement is such a powerful tool to complement clinical judgment, helping surgeons confirm impressions or identify unseen flow limitations while corrective action is still possible.
Flow Assisted Surgical Technique (FAST) uses transit-time ultrasound to provide quantitative, intraoperative measurements that support surgeons during those pressing moments. FAST can be used during a variety of cerebrovascular procedures, including:
- Aneurysm clipping surgery
- Arterial EC-IC bypass surgery
- Arteriovenous malformation (AVM) resection
- Venous EC-IC bypass surgery
- STA-MCA bypass for Moyamoya
