AB  - Stent-assisted coil embolization (SACE) is a common method to manage intracranial 
      wide-neck aneurysm. Using this technique, a stent must be successfully deployed 
      into the parent artery to cross the aneurysm neck. We describe the reverse waffle 
      cone technique in management of intra-procedural stent dislodgement during SACE 
      of internal carotid artery (ICA) wide-neck aneurysms. Two patients with 
      unruptured wide-neck ICA aneurysms underwent SACE. Intra-procedural forward stent 
      migration occurred during catheterization with proximal stent dislodgement and 
      migration into the aneurysm sac. Navigation of a second stent to bridge the 
      aneurysm neck failed in one patient because the second stent was impeded by the 
      dislodged stent. Using the reverse waffle cone technique, a microcatheter was 
      navigated into the aneurysm sacs. Coils were safely detached into each aneurysm 
      sac without any device assistance. The two wide-neck aneurysms were successfully 
      treated with preservation of flow to the internal carotid arteries. The 
      complication of intra-procedural distal stent migration and dislodgement, with 
      proximal stent prolapse into an aneurysm sac, may not result in a failure to coil 
      the aneurysm. The reverse waffle cone technique provides an effective treatment 
      in the management of this complication.
