“Flow is a vital parameter during cerebrovascular surgery; including flow in my surgical approach gives me a high degree of control over surgical outcome. When I close the patient, I know the patient will recover without ischemia surprises. This translates into peace of mind for the patient and me, and saves money for the hospital.” F Charbel, MD, FACS
“…In combination with intraoperative neurophysiological monitoring, intraoperative flow may now constitute the most reliable tool for increasing safety in aneurysm surgery.” A Pasuqalin, MD
Intraoperative measurements take the guesswork out of blood flow assessment during aneurysm clipping, extracranial to intracranial (EC-IC) bypass surgeries, arteriovenous malformations (AVMs), dural fistula obliteration, and tumor resection surgeries.
During aneurysm clipping surgery, flow measurements help surgeons achieve optimal clip placement to obliterate the aneurysm without compromising flow in parent vessels and distal branches. Measurements either confirm the surgeon’s clinical assessment of flow preservation, or expose the need for immediate correction of flow deficits. During temporary clippings, flow measurements offer an assessment of collateral flow reserve and predict the safety of the temporary clipping.
During EC-IC bypass surgery to preserve or augment distal cerebral perfusion, flow measurements aid the surgeon in choosing the most appropriate bypass and predicting its future patency. Intraoperative blood flow measurements thus provide invaluable quantitative flow information for a surgeon’s armamentarium to:
- Identify Inadvertent Vessel Compromise
- Confirm Flow Preservation
- Quantify Flow Augmentation
