Dopplers in Neurological Surgery
The 20 MHz Microvascular Doppler System has become an indispensable intraoperative tool for the neurosurgeon. The real-time assessment of vessels allows for a safer and more cost-effective neurological procedure by reducing the need for intraoperative angiograms.
Neurological Procedures
- Aneurysm Clipping
- Arterio-venous malformations
Doppler Uses
- Determines patency of parent vessel after aneurysm clipping
- Determines completeness of aneurysm clipping
- Locates feeder artery in AVM
- Locates major venous sinuses
- Localizes vessels noted on angiogram
Use of an intraoperative microvascular Doppler to evaluate the patency of parent and branching vessels and assess the adequacy of obliteration of the aneurysmal sac has been shown to result in repositioning of the aneurysm clip in 24% to 31% of patients.1
