Abstract

A 0.010 inch diameter ED coil (Kaneka medics, Kanagawa, Japan) was newly developed and came to market recently. Early experiences using this detachable coil are reported. Fifteen intracranial saccular aneurysms were treated at our institution since Oct. 2006. There are soft and extrasoft type-10 ED coils and the both types were used. Fifty-one coils were deployed for 15 aneurysms. As the coil part and junction with the delivery wire is very soft, type-10 ED coils are easy to advance even in a very tortuous vessels and less likely to unintentionally move a microcatheter due to friction than other available detachable coils. There were no premature detachments, no coils unraveled, and no failures to detach. As for case complications, there was no intraprocedural aneurysmal ruptures and no thromboembolisms. There was one instance of coil migration with the smallest and shortest coil. It resulted in a small asymptomatic infarction. As the coil is itself very soft, smaller ones should be more carefully deployed within the coil basket to avoid coil migration. The device was considered to be effective and safe for endosaccular embolization of cerebral aneurysms.
