Figure 1
Flow diversion concept: placement of a high-mesh density stent (flow diverter) in the parent vessel disrupts blood flow into the aneurysm (A and B), allowing for progressive intra-aneurysmal thrombosis over time with subsequent obliteration of the aneurysm (C and D). Additionally, the flow diverter provides a scaffold for neoendothelialisation, which treats the weakened abnormal arterial wall and isolates the aneurysm from the parent circulation resulting in durable occlusion of the aneurysm (E).
