Double microcatheter technique for detachable coil treatment of wide-necked intracranial aneurysms / 介入放射学杂志

ABSTRACT

Objective To evaluate double microcatheter technique for detachable coil treatment of wide-necked intracranial aneurysms. Methods Routine endovascular coil occlusion was not achieved in 6 cases of wide-necked intracranial aneurysms. A second femoral arterial sheath was inserted on the opposite side . A second microcatheter was positioned within the aneurysm. The detachable coils were introduced via double microcatheter simultaneously or successively till the aneurysm were compactly embolized. The coils were detached after satisfactorily positioned. Results Total 6 cases of wide-necked aneurysms were successfully embolized with detachable coil. Aneurysmal sacs were 100% embolized in 2 cases, over 90% in 4 cases. 1 case suffered moderate disablement as a result of complication of. Angiographic follow-up in 5 cases revealed no recurrent or rerupture.Conclusions The double microcathter technique may be an optional method during embolization of some complicated wide-necked aneurysms.
