The pCONus device for the endovascular treatment of wide neck bifurcation XXXX .

@entity1 @entity439 @entity1031 @entity438
BACKGROUND AND PURPOSE: The pCONus is a new stent featuring a distal end that opens like a blossoming flower with four petals. The device is implanted in the @entity439 sac at the level of the neck. We report our initial experience in a series of @entity1 treated with this device. METHODS: This retrospective study was approved by the authors' ethics committees. 18 @entity1 with 19 unruptured wide neck bifurcation @entity438 ( @entity438 ) were treated by pCONus placement and coiling. Technical issues, immediate post treatment angiographic findings, and clinical and imaging follow-up were assessed. RESULTS: Embolization was successful in all @entity1 . There were 11 @entity1 and 7 @entity1 with a mean age of 60   years. Median @entity439 size was 9   mm (range 5.5-25   mm). The device was precisely placed and detached in all cases, allowing for subsequent coiling. Two @entity1 experienced a symptomatic complication, one of which, a @entity1031 , was related to the use of the pCONus. This @entity1 had a slight hand paresis. 16 @entity1 had a normal neurological examination at discharge. Immediate anatomical results were 13 complete occlusions, 2 neck remnants, and 4 incomplete occlusions. Imaging follow-up was obtained in 12 @entity1 (mean 9.5   months, range 2-24 months) and showed 9 stable occlusions and 3 recanalizations, of which 2 were retreated. CONCLUSIONS: In this initial series of @entity1 , endovascular treatment of wide neck bifurcation IAs with the pCONus was feasible, with acceptable clinical and anatomical outcomes. Further studies are needed to evaluate the indications, safety, and efficacy of this new device.
