P-019 Comparative effectiveness of stent-assisted coiling and woven endobridge (WEB) embolization for the treatment of unruptured wide-neck bifurcation intracranial aneurysms

ConclusionMid-term complete and adequate occlusion rates were similar between patients treated with WEB and SAC. Given the comparable outcomes, there may be equipoise in treatment options for WNBAs.Abstract P-019 Table 1Baseline patient and aneurysm morphology parameters between treatment groups Aneurysm parameters* WEB (n=27) Stent-coil (n=54) p-value Age 63 (50–69) 65 (57–69) 0.511 Gender, male 6 (22%) 12 (22%) 1.000 Smoking Status Current smoker 9 (33%) 9 (17%) 0.235 Prior Smoker 9 (33%) 22 (41%) Never Smoker 9 (33%) 23 (43%) Location Acomm 9 (33%) 20 (37%) 0.772 Basilar apex 6 (22%) 17 (32%) Carotid terminus 1 (4%) 2 (4%) MCA bifurcation 11 (41%) 15 (28%) Width (mm) 5.1 (4.0–6.3) 5.2 (4.2–6.5) 0.880 Neck (mm) 3.2 (3.0–4.5) 4.0 (3.2–4.7) 0.206 Dome-to-neck ratio 1.6 (1.2–1.8) 1.3 (1.2–1.6) 0.091 *Continuous variables reported as median (IQR) due to non-normality of the data Abbreviations: Acomm – anterior communicating artery; MCA – middle cerebral arteryAbstract P-019 Table 2Follow up imaging data Outcomes WEB (n=27) Stent-coil (n=54) p-value Follow up duration (days) 203 (113–494) 504 (196–791) 0.001** 3–6 month MRA* 24 (89%) 41 (76%) 0.239 Complete occlusion 16 (67%) 28 (68%) 0.705 Residual neck 7 (29%) 9 (22%) Residual aneurysm 1 (4%) 4 (10%) Angiographic outcome* 8 (30%) 14 (26%) 0.724 Complete occlusion 5 (63%) 11 (79%) 0.800 Residual neck 1 (13%) 1 (7%) Residual aneurysm 2 (25%)...
