Microcatheter Looping to Facilitate Aneurysm Selection in Coil Embolization of Paraclinoid Aneurysms

摘要: Described herein is a microcatheter looping technique to facilitate aneurysm selection in paraclinoid aneurysms, which remains be technically challenging due the inherent complexity of regional anatomy.This retrospective study was approved by our Institutional Review Board, and informed consent waived. Microcatheter method employed 59 patients with aneurysms between January 2012 December 2013. In described technique, construction loop, steam-shaped or pre-shaped, based on direction mandatory. The looped tip advanced into distal internal carotid artery positioned atop target aneurysm. By steering loop (via inner microguidewire) dome easing tension microcatheter, selected. Clinical morphologic outcomes were assessed emphasis technical aspects treatment.Through this total successfully treated. After as described, single (n = 25) most commonly used coiling, followed balloon protection 21), stent 7), multiple microcatheters 3), stent/balloon combination 3). Satisfactory aneurysmal occlusion achieved through coil embolization 44 lesions (74.6%). During follow-up 53 (mean interval, 10.9 ± 5.9 months), only one instance (1.9%) major recanalization observed. There no complications related looping.This facilitates safe effective positioning domes during when other traditional methods otherwise fail.
