Rescue waffle cone technique for managing stent dislodgement into a target aneurysm

Stent-assisted coiling is an essential technique for managing wide-neck intracranial aneurysms. However, complications such as stent dislodgement can pose significant challenges, potentially compromising procedural success and patient outcomes. We present the case of a 73-year-old woman with an unruptured basilar tip aneurysm who experienced intra-procedural stent dislodgement into the target aneurysm during a Y-stent-assisted coiling attempt. Recognizing the instability of the displaced stent and the risk of further complications, we employed a modified "waffle cone technique" using a Solitaire AB stent to successfully secure the aneurysm while preserving parent vessel patency. This case highlights the importance of prompt recognition and innovative problem-solving strategies in managing stent-related complications during neuro-interventions. The rescue waffle cone technique represents a viable alternative for addressing complex stent dislodgement scenarios and improving patient outcomes.
