Vessel Curvature and Microcatheter-Detachable Coil Compatibility in Arterial Coil Embolization. [PDF]

Cureus
Abstract Purpose: This study examined whether sharp vessel angulation (≥90–180°) and microcatheter–detachable coil compatibility independently increase coil maldelivery in non-neuro arterial embolization, and how these factors affect technical failure and salvage strategies.

Chronological Changes in Intra-aneurysmal Signal Intensity on T1-weighted Black Blood Images after Endovascular Treatment for Unruptured Intracranial Aneurysms

Neurologia Medico-Chirurgica
Intra-aneurysmal thrombus formation is crucial for the healing of endovascularly treated aneurysms. This study evaluated whether T1-weighted black blood imaging can monitor thrombus formation by examining the relationship between chronological signal ...

Aneurysm permeability following coil embolization: packing density and coil distribution [PDF]

Journal of NeuroInterventional Surgery, 2014
BackgroundRates of durable aneurysm occlusion following coil embolization vary widely, and a better understanding of coil mass mechanics is desired. The goal of this study is to evaluate the impact of packing density and coil uniformity on aneurysm permeability.MethodsAneurysm models were coiled using either Guglielmi detachable coils or Target coils ...
