OBJECTIVE

To evaluate the effectiveness of augmented reality (AR) as a neuronavigation method in performing extracranial-intracranial microanastomosis.

MATERIAL AND METHODS

This study included a patient who underwent an extracranial-intracranial microanastomosis with proximal clipping of a giant fusiform partially thrombosed aneurysm of the right middle cerebral artery. AR technology using Microsoft Hololens 2 augmented reality glasses and software from MEDGITAL LLC was utilized for preoperative planning and intraoperative navigation. Anatomical data from preoperative angiography were integrated into a 3D matrix and overlaid onto the surgical field. Accuracy of marking, time, and ease of use were evaluated.

RESULTS

The use of AR significantly improved the visualization of the donor vessel (STA) during its dissection. AR also enhanced the precision of performing the craniotomy above the recipient vessel. No intraoperative or postoperative complications occurred.

CONCLUSION

AR technology demonstrated its effectiveness in preoperative marking and performing extracranial-intracranial microanastomosis. It facilitates artery identification and potentially reduces the risk of complications associated with their injury. Further studies should include comparisons with traditional methods to definitively assess the advantages of AR.
