      embolization of basilar apex aneurysms: technical report.

AB  - BACKGROUND: The endovascular treatment of large, wide-necked basilar apex 
      aneurysms (BAAs) remains challenging. Although horizontal stent deployment across 
      both P1 segments of the posterior cerebral arteries (PCAs) would be an optimal 
      strategy in coil embolization of wide-necked BAAs, this is only feasible in cases 
      with anatomically favorable access. In rare circumstances, large-diameter 
      conduits of extracranial-intracranial (EC-IC) bypass can also provide a good 
      access route for endovascular treatment of complex intracranial aneurysms. 
      METHODS: We describe the technique of accessing the PCA via EC-IC bypass grafts 
      and deploying a stent horizontally across the neck of BAA and its coil 
      embolization. We provide a detailed technical review and describe some pitfalls 
      of the procedure. RESULTS: Two patients underwent EC-IC bypass surgery prior to 
      the treatment of a large, wide-necked BAA. The radial artery and saphenous vein 
      were used as grafts, respectively. To facilitate coil embolization for a large 
      BAA, a PCA-to-PCA horizontal stent was deployed via the bypass graft. Trans-cell 
      and jailing techniques were used, respectively. Both aneurysms were completely 
      occluded, and the patients were discharged without any neurological deficit. 
      CONCLUSION: Horizontal stent deployment via EC-IC bypass grafts can be performed 
      safely, providing proper closure of the aneurysmal neck and apposition to both 
      PCAs, facilitating complete coil embolization.
