The case study looks at a 35-year-old female patient with Moyamoya disease who presented with worsening neurological signs and symptoms. The decision was made to perform bypass surgery.
Before the bypass surgery, a pre-operative assessment was performed including catheter angiography and digital subtraction angiography (DSA). This allowed to better understand the occlusions and stenosis.
As a first step, the surgeon dissected the superficial artery. The use of GLOW800 Augmented Reality fluorescence enables the assessment of the blood flow through the artery. It also allows to check for potential hemorrhaging and thrombosis.
A pterional craniotomy was performed, followed by the subarachnoid dissection through the Sylvian fissure.
Prior to the anastomosis, GLOW800 was used to assess the cerebral blood flow through the feeding arteries and the M4 branch. The anastomotic mouth of the temporal artery was performed for the bypass.
After completing the bypass, GLOW800 was instrumental to assess the patency of the arteries and ensure the absence of hemorrhages and thrombosis. The postoperative evaluation showed no signs of postoperative complications or new neurological deficits.
The use of GLOW800 Augmented Reality fluorescence provides one augmented real-time view during vascular neurosurgery. Neurosurgeons do not need to recall and try to reconcile the black and white blood flow video with the natural anatomical view. The crisp delineation, full depth perception and absence of dark peripheries supports precise manipulation of vessels.
With GLOW800 Augmented Reality, it is possible to:
- Perform an accurate assessment of blood flow during bypass surgery through the feeding and receiving vessels, aiding in their selection
- Identify the presence of thrombosis or stenosis of vessels before anastomosis and do an intraoperative assessment of the patency of anastomosis
- Intraoperatively assess blood hemorrhage through anastomosed blood vessels, including kinking and partial obstruction.
As such, GLOW800 supports Moyamoya disease treatment and outcomes and is a fundamental tool for the future of practice and training in neurosurgery. Want to learn more? Register below to download the full case study and access the clinical videos.
