O-018 Single Institution Experience with Two Flow Diverters: A Head to Head Comparison

ConclusionWe present a single institutional experience with two flow diverting stents. There was no significant difference in neurological morbidity or mortality. There was a trend towards a higher rate of complete occlusion with the FRED device.There was no significant difference between the complication rates for the two groups, including ipsilateral ischemic stroke, ipsilateral ICH, aneurysm rupture and overall neurological morbidity and mortality.Abstract O-018 Table 2The complications associated with each deviceFREDICA > 10 mm(n = 10)ICA < 10 mm(n = 7)All(n = 19)Ipsilateral Ischemic Stroke1 (10%)1 (14%)2 (10.5%)Ipsilateral ICH0 (0%)0 (0%)0 (0%)Aneurysm Rupture0 (0%)0 (0%)0 (0%)Neurological Morbidity & Mortality1 (10%)1 (14%)2 (10.5%)PipelineICA > 10 mm (n = 3)ICA < 10 mm (n = 26)All(n = 36)Ipsilateral Ischemic Stroke0 (0%)2 (7.7%)3 (8.3%)Ipsilateral ICH0 (0%)1 (3.8%)1 (2.7%)Aneurysm Rupture0 (0%)0 (0%)0 (0%)Neurological Morbidity & Mortality0 (0%)3 (11.5%)4 (11.1%)There was no significant difference in occlusion rate between the two groups. There was a trend towards a higher rate of complete occlusion in the FRED group but this was not statistically significant (p = 0.17). When only saccular aneurysms were evaluated, the complete occlusion rate in the FRED group was 92.3% and 70% in the pipeline group (p = 0.2).Abstract O-018 Table 3Results of each deviceFREDAnteriorAll6 month angiographic complete occlusion11/13 (84.6%)11/14 (78.6%)12 month angiograp...
