Objective:

To present a single-stage hybrid surgical approach for managing ruptured dissecting fusiform proximal PICA aneurysms, highlighting its potential to improve patient outcomes.

Key Findings:
  • The hybrid approach allows for simultaneous microsurgical and endovascular intervention, potentially reducing overall procedure time.
  • Successful PICA–PICA bypass maintained blood flow during aneurysm treatment, with no observed complications.
  • Complete occlusion of the aneurysm was achieved without compromising PICA patency, as confirmed by intraoperative imaging.
Interpretation:

This technique demonstrates a feasible and effective method for treating complex PICA aneurysms in a single surgical stage, potentially reducing patient risk and recovery time compared to traditional multi-stage approaches.

Limitations:
  • The approach may not be applicable to all PICA aneurysms due to anatomical variations, particularly in vessel size and location.
  • Limited literature on the hybrid technique for PICA aneurysms necessitates further studies to validate its efficacy and safety.
Conclusion:

The single-stage hybrid strategy for ruptured dissecting fusiform proximal PICA aneurysms is a promising approach that combines microsurgical and endovascular techniques, potentially enhancing patient outcomes and reducing recovery time.
