Abstract

Background and purpose: Barricade coils (Blockade/Balt, Montmorency, France) are bare platinum coils, electrically detached existing in different shapes, softnesses, and sizes. This series is analyzing the safety (procedural complications) and efficacy (anatomical results at 1-year) of these coils in a prospective, single-center series.

Materials and methods: All patients with aneurysms treated with Barricade coils, without associated treatment (flow diverter, flow disrupter, or surgery) or parent artery occlusion were included. Peri-operative complications were evaluated. Anatomical results at 1-year were analyzed for patients that completed the 1-year digital subtraction angiographic follow-up and were independently evaluated by an expert neuroradiologist.

Results: During the study period (October 2013 – October 2017), 132 patients (Female: 88/132, 66.7%; Median age: 50 years) with 141 aneurysms treated with Blockade coils were included. Aneurysm rupture, thromboembolic complication, and technical problems occurred 9 aneurysms (6.3%), 8 aneurysms (5.6%), and 8 aneurysms (5.6%), respectively. Clinical consequences were variable; morbidity was reported in 5 patients (3.8%) and mortality in 2 patients (1.5%).

Post-operatively aneurysm occlusion was complete in 117 aneurysms (83.0%), neck remnant in 16 aneurysms (11.3%), and aneurysm remnant in 8 aneurysms (5.7%).

At 1-year aneurysm occlusion was complete in 53 aneurysms (51.5%), neck remnant in 34 aneurysms (33.0%), and aneurysm remnant in 16 aneurysms (15.5%). Retreatment in the year following the initial treatment was reported in 10 aneurysms (9.7%).

Conclusion: Treatment of ruptured, unruptured, and recanalized aneurysms with Barricade coils is associated with a good safety and 1-year efficacy.
