Hemodynamics and coil distribution with changing coil stiffness and length in intracranial aneurysms.
PURPOSE The purpose of this study was to investigate hemodynamics and coil distribution with changing coil stiffness and length using the finite element method (FEM) and computational fluid dynamics (CFD) analysis. METHODS Basic side-wall and bifurcation type aneurysm models were used. Six types of coil models were generated by changing the coil stiffness and length, based on commercially ava...
متن کاملThe learning curve for coil embolization of unruptured intracranial aneurysms.
BACKGROUND AND PURPOSE Several studies have shown that procedural outcomes are better at high-volume institutions, possibly due to greater physician experience (learning) or practice (repetition). Our purpose was to determine whether outcomes for coil embolization improved with the experience of the practitioner, after adjusting for the perceived risk of treatment. METHODS We identified all u...
متن کاملSingle-session Coil Embolization of Multiple Intracranial Aneurysms
OBJECTIVE There is no clear treatment strategy for the management of multiple intracranial aneurysms because of variable anatomical distribution, difficult identification of the aneurysm ruptured, and poor overall outcomes. The purpose of this study was to assess the efficacy and safety of single-session coil embolization for multiple intracranial aneurysms. METHODS Between September 2008 and...
متن کاملBailout stent deployment during coil embolization of intracranial aneurysms.
BACKGROUND AND PURPOSE Self-expandable stents are an effective tool for coil embolization of wide-neck intracranial aneurysms. The purpose of this study was to assess the feasibility and results of bailout stent positioning during rescue situations after deployment of > or =1 coil. MATERIALS AND METHODS Among 318 aneurysms treated by coil embolization in 267 patients, 16 patients who were tre...
متن کاملCoil embolization for intracranial aneurysms: an evidence-based analysis.
OBJECTIVE To determine the effectiveness and cost-effectiveness of coil embolization compared with surgical clipping to treat intracranial aneurysms. THE TECHNOLOGY Endovascular coil embolization is a percutaneous approach to treat an intracranial aneurysm from within the blood vessel without the need of a craniotomy. In this procedure, a microcatheter is inserted into the femoral artery near...
