Abstract

Background and PurposeThe Barrel device is an electrolytically detachable laser cut, closed-cell microstent that is used for neck reconstruction in wide-necked bifurcation and branching aneurysms to support coiling. The key feature is abarrel section that herniates over the aneurysmal ostium. The objective was to evaluate the safety, feasibility and the immediate and mid-term occlusion results of this new device.Material and MethodsThe databases of two tertiary care centers were screened for all Barrel-based stent-assisted intracranial coil embolization of wide-necked aneurysms between June 2015 and September 2016. Case files and imaging data were retrospectively analyzed for angiographic and clinical outcome parameters, including immediate and mid-term modified Raymond-Roy aneurysm occlusion classification (RROC) rates and procedural complications.ResultsA total of 21 patients comprising 21intracranial aneurysms (20unruptured, 1ruptured) were treated with the Barrel device and additional coiling of the aneurysm sac. All aneurysms were wide-necked, saccular bifurcation aneurysms defined by adome/neck ratio 2. Immediate complete occlusion (RROC1) was observed in 19/21 (90%). An intra-interventional in-stent thrombus formation in two cases (10%) was medically resolved without neurological sequelae. Asingle case of symptomatic in-stent stenosis (5%) was cleared by balloon angioplasty. Follow-up (FU) was available in 20/21 cases (95%) after amedian of 282 days (range: 17-591 days). At follow-up 19/20 aneurysms (95%) were completely occluded (RROC1).ConclusionThe Barrel device showed asatisfactory safety profile and apromising rate of immediate and mid-term complete aneurysm occlusion for stent-assisted coil embolization of wide-necked intracranial bifurcation aneurysms, warranting further investigation of the device.
