The “CUPCAKE” technique (coiled underlying pseudoaneurysm contained by a woven endobridge device) for treating intracranial aneurysms with atypical morphology:
- The CUPCAKE technique, which integrates conventional coiling with WEB intrasaccular flow disruption, was evaluated in a retrospective study across three Australian neurovascular centers from April 2018 to September 2023.
- It was applied in 22 of 169 cases treated with WEB, achieving a 95.5% success rate in immediate flow stagnation.
- The technique showed minimal complications, with thromboembolic issues in two patients and one requiring retreatment.
- Follow-up imaging showed 88.2% complete aneurysm occlusion, with no instances of delayed expansion or rupture, demonstrating its effectiveness in treating complex aneurysms unsuitable for conventional WEB alone.
