Validation studies of virtual reality simulation performance metrics for mechanical thrombectomy in ischemic stroke.

abstract：BACKGROUND:Coil occlusion has become the standard treatment for many ruptured aneurysms. However, specific aneurysm structures pose technical difficulties and may require the use of adjunctive neck-bridging devices, which necessitate the use of dual antiplatelet therapy. The hydrophilic polymer coating (pHPC, phenox) i...
