Abstract

Abstract : Background: Multiple flow diversion embolization devices have currently been used to treat side wall intracranial aneurysms. However, there are no robust head-to-head comparison studies of these devices in clinical practice. We sought to compare two major flow diverters used, Pipeline vs Surpass in operative and post-operative settings. Method: We retrospectively analyzed our procedural database for use of all flow diverters including pipeline vs surpass flow diverters. Baseline demographic variables were collected and compared between each group. In addition, safety variables such as procedural or post-procedural complications were compared between the two groups. Results: A total (=n) of 221 were included in this retrospective chart review. 179 (81%) were pipeline cases. Baseline smoking status was similar between both groups. Majority were unruptured aneurysms and only close to a quarter in each of the groups. The width (in mm) was significantly smaller in pipeline cases [3.9 mm (2.5 - 7) vs surpass [6.1 mm (3.9 - 9.5); p value of 0.008]. Safety outcomes including intracranial hemorrhage (0% vs 0%), stroke [2 (1%) vs 2 (4%)], seizure [1 (0.5%) vs 1 (2%)], intracranial hypertension [4 (2%) vs 0%], vasospasm [3 (2%) vs 0%]], vessel perforation [0% vs 0%], thrombus formation [0% vs 1 (2%)], aneurysm rupture (0% vs 0%) was comparable between pipeline vs surpass flow diverter groups and with no statistical significance. Conclusions: In our single-center retrospective experience in the last 5 years, the Pipeline and Surpass were comparable except that the Surpass flow diverter cases tended to have a higher baseline aneurysm width compared to Pipeline. However, the procedural outcomes and complication rates were comparable between both groups. Long-term and follow-up data to be evaluated for efficacy outcomes assessment. Disclosures: A.
