Transonic Flow-QC provides immediate & quantitative
mean flow measurements with documentation of the phasic flow pattern. These enable more precise
surgical interventions, and reduce the risk of vascular complications and stroke.
|
In seconds, Transonic Flow-QC provides an on-the-spot, functional assessment of true volume flow in ml/min or L/min.
Final intraoperative flow check averts complication. (Case study)

Charbel Micro-flowprobe
Patented by Transonic Systems the micro-flowprobe is
especially designed for aneursym surgery with a bayonet-style handle to access cerebral vessels.

Testimonials
AVM Removal Surgery - Dr. Khurana, Canberra Hospital, Australia
"Flow reduction of more than 50% of baseline values signficantly predicts ischemic complications. The innovative
role of intraoperative flowmetry is that it consents serial quantitative recordings, corroborating or contradicting
subjective surgeon assessment about vessel flow integrity. Intraoperative quantitative cerebral blood flow monitoring is a
safe and useful technique, fast, easy to perform and to repeat. Moreover, flowmetry-assisted aneurysm clipping offers the
surgeon useful hemodynamic information during clipping procedures, allowing safer clip placement, especially in the
repair of complex or broad-based cerebral aneurysms."
Pavesi, G. et al. “Flowmetry Assisted Aneurysm Clipping. An Italian Cooperative
Study” 13th World Congress of Neurological Surgery, Marrakesh, June, 2005.
"We found transit time flow measurement useful for management of cerebrovascular surgery: the technique was simple to use and provided stable,
reliable results. The method was able to reveal distal branch flow diminution in aneursym clipping, or residual flow during temporary clipping in aneursym surgery,
and has potential to predict post-operative complications such as hyperperfusion by signalling over-elevation of donor artery flow in bypass surgery or ICA flow in
carotid surgery."
Nakayama, N. et al. Acta Neurochirurgia,2001; 143:17-24.
The Charbel Flow-based Technique
helps you achieve better surgical outcomes! 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 whether clip placement obstructs flow.
EC/IC Bypass
Intraoperative flow measurements during construction of an arterial or venous EC-IC bypass provides the surgeon with information to:
- Select the best bypass match
- Access the adequacy of a bypass before completing its construction
- Immediately evaluate the quality of the bypass
ELANA Technique:creating non-occlusive anastomoses during cerebrovascular bypass surgery
The Excimer Laser-Assisted Non-occlusive Anastomosis (ELANA) Technique, pioneered by Professor C.A.F. Tullekan of Utrecht University, Netherlands, enables construction of high flow bypasses with non-occlusive anastomoses. Transonic intraoperative flow measurements are part of their preoperative protocol.
Carotid Endarterectomy
Flow Monitoring confirms and documents the quality of your endarterectomy. Flow measurement of carotid arteries documents improved flows. Flow monitoring
through Javid and/or Pruitt/Inahara Shunts safeguards brain perfusion.
