Calcified cerebral emboli (CCE) are a rare cause of acute ischemic stroke, frequently associated with very low recanalization rates and poor outcomes.
With the support of the Neuro Thromboembolic Initiative ressources , authors were able to develop appropriate calcified replicates in an M1 in silico occlusion model.

Four different endovascular approaches were evaluated (6 attempts):
BGC+Dual asp.
No flow arrest
CONCLUSION
CCE were characterized here and appeared considerably stiffer than thrombus.
Combined technique associated with proximal flow control was associated with better but unsatisfactory results.
The successful development of such a CCE model should allow the evaluation of further solutions.
