Abstract 109: Surpass NeuroEndograft for Endovascular Treatment of Intracranial Aneurysms -Single Center Clinical and Angiographic Results
Purpose: The Surpass NeuroEndograft (Surpass FD, Tel Aviv, Israel), a low porosity, high pore density flow diverting (FD) device, was evaluated for the treatment of intracranial aneurysms in a single center.
Materials and Methods: A total of 45 aneurysms in 35 patients were treated. To achieve the calculated flow disruption between the parent artery and aneurysm and required for an occlusion, single devices, tailored to local boundary conditions, were placed endovascularly in parent arteries and covering the aneurysm. Implanted devices measured 2.9-5.3mm in diameter with a length of 10-50mm. Thirty-five aneurysms had complete neck coverage after implantation and ten bifurcation aneurysms had a planned incomplete neck coverage.
Results: Six-month follow-up angiography available for 28 aneurysms with complete neck coverage, showed a complete occlusion in 27 aneurysms and a less than 50% occlusion in one, resulting in a 96% occlusion rate. Five aneurysms with incomplete neck coverage had complete occlusion at six months follow-up, and four had less than 50% occlusion. There were two parent artery occlusions, leading to a permanent stroke in one patient. There were no other permanent neurological morbidities and there was no mortalitiy., thus permanent morbidity in these series was 2,9%. Infarctions caused by occlusion of perforating arteries covered by the implant during the follow-up period were not seen.
Conclusion: Preliminary data demonstrate in treatment of complex aneurysms the efficacy of a new generation of FD device.
