OBJECTIVETo discuss the avail of balloon and stent-assisted Guglielmi detachable coil (GDC) placement in treatment of wide-necked cerebral aneurysm.

METHODSEighty-seven patients with 92 wide-necked aneurysms undergone endovascular procedures using the balloon and stent-assisted remodeling technique. Respectively, appropriate Neuroform stents delivered with a 5 mm landing zone on either side of the aneurysm neck, the microcatheter entered through the interstice, aneurysms were embolized at one or several times. Two catheters were used in balloon-remodeling technique, balloon were inflated across the neck of the aneurysms after the microcatheter entering the aneurysms, then the GDC were used to embolize the aneurysms.

RESULTSThirty-one aneurysms were completely occluded, 3 subtotally (> 90%) and 1 incompletely (70% - 90%) occluded using stent-assisted technique, all carry arteries were unblocked, 3 patients with mild neurological dysfunction and no mortality. Fifty aneurysms were completely occluded and 4 incompletely occluded using balloon-assisted technique, 1 patients with mild neurological dysfunction and no mortality. Two aneurysms were completely occluded and 1 incompletely occluded using stent-assisted and balloon-assisted technique. The mean period of follow-up was 5.8 months. Rates of recanalization were 16.7% for stent-remodeling group and 12.5% for balloon-remodeling group.

CONCLUSIONSThe stent and balloon-assisted remodeling technique are safe and effective in treating wide-necked aneurysms. Balloon-remodeling technique has more security comparing with stents.
