Pioneered by Dr. Fady Charbel at the Unviersity of Illinois at Chicago, F.A.S.T. guides a neurosurgeon's intraoperative strategy for flow preservation, flow replacement, or flow augmentation during aneurysm surgery.
Aneurysm Clipping Surgery
Flow Preservation
During temporary clip application, Transonic Flow-QC tells whether flow is maintained to critical parts of the brain. When a permanent aneurysm clip is applied, Transonic Flow-QC tells you conclusively that flow is preserved or whether clip placement has obstructed flow.
Flow Replacement
During clipping of complex aneurysms with parent vessel sacrifice and construction of an EC-IC bypass, a flow-based strategy assesses the adequacy of an EC-IC bypass to replace flow when an aneurysm is trapped and a vessel sacrificed.
- F.A.S.T. detects compromised flow when it can be readily corrected to avoid diasterous intraoperative stroke
- F.A.S.T. offers an on-the-spot functional assessment of flow during complex surgical obliteration of aneurysms or AVMs.
- F.A.S.T. provides quantitative documentation for the patient's record
EC- IC Bypass for Treatment of Cerebrovascular Occlusive Disease
Flow Augmentation
Intraoperative measurements provide quantitative feedback on the increase in flow provided by EC-IC bypasses when treating carotid artery occlusive disease or Moyamoya syndrome.
