Abstract:

Objective To investigate the value of virtual reality based on three-dimensional CT angiography (3D-CTA) in treatment of cerebrovascular diseases. Methods Twenty-one patients with cerebrovascular diseases were examined with 3D-CTA scanning. Operative approaches were simulated by virtual reality technique, operations were performed under the guidance of simulative approaches, and comparisons were made between surgical findings and simulative images. Results Operations were successfully performed under the guidance of simulative approaches in all the 21 patients, and no severe complications occurred. The surgical findings were highly consistent with preoperative rehearsal. Conclusion Virtual reality based on 3D-CTA in cerebrovascular diseases can well simulate operative approaches, clearly illustrate the size, shape and position of the lesion, and reflect the supply arteries and spatial relationship, which can guide the operation.

Key words: three-dimensional CT angiography, virtual reality, cerebrovascular diseases, operation
