Increasing the packing of small aneurysms with complex-shaped coils: an in vitro study.
نویسندگان
چکیده
Nine embolization experiments of a silicone aneurysm model were conducted by using helical and complex-shaped coils. Coils were introduced up to the point when the adjunct of a supplementary coil caused protrusion into the parent vessel. Packing ratios (volume of coils-aneurysm volume) ranged between 31% and 38%. Optimal packing was achieved with complex-shaped coils used in a concentric fashion. The complex-shaped coils allowed a better aneurysm filling than did helical coils.

Coil thickness and packing of cerebral aneurysms: a comparative study of two types of coils.
BACKGROUND AND PURPOSE In coiling cerebral aneurysms, high packing prevents reopening over time. The purpose of this study was to compare packing of cerebral aneurysms treated with two types of coils with different wire thickness and different shapes. METHODS Packing, defined as the ratio between the volume of inserted coils and the volume of an aneurysm, was calculated for 144 cerebral aneur...
متن کاملComplex-shaped platinum coils for brain aneurysms: higher packing density, improved biomechanical stability, and midterm angiographic outcome.
BACKGROUND AND PURPOSE Five to 60% of coiled brain aneurysms recanalize, generally because of coil compaction. In vitro exclusive use of complex-shaped coils allows better packing of the aneurysmal sac and the neck as compared with helical coils. We report a single-center, prospective study using complex coils. Safety, packing density, and recanalization rate were evaluated. MATERIALS AND MET...
متن کاملThree-dimensional packing with complex orbit coils for the endovascular treatment of intracranial aneurysms.
BACKGROUND AND PURPOSE Endovascular treatment of intracranial aneurysms is too often associated with aneurysm recurrence due to coil compaction. High packing of coils prevents compaction. To increase the packing attenuation, we sought to evaluate the results of selective embolization of aneurysms with complex-shaped coils alone. METHODS Twenty consecutive patients with an intracranial aneurys...

BACKGROUND AND PURPOSE The purpose of this study was to retrospectively compare the packing performance of helical Guglielmi detachable coil (GDC) 18 (thickness, 0.0135-0.015 inch) with the packing performance of both helical GDC 10 (thickness, 0.010 inch) and complex Trufill/Orbit coils (thickness, 0.012 inch). MATERIALS AND METHODS From our data base, we selected aneurysms that were exclusi...

OBJECTIVE Based on the use of Nano™ coils, we retrospectively compared the proportion of the coils (≤ 1.5 mm) and packing density in two patient groups with small cerebral aneurysms (< 4 mm diameter) who were treated with or without Nano™ coils. MATERIALS AND METHODS Between January 2012 and November 2013, in 548 cerebral aneurysms treated by endovascular coiling, 143 patients with 148 small ...
