RT Journal Article SR Electronic T1 Endovascular extraction of malpositioned fibered platinum microcoils from the aneurysm sac during endovascular therapy. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 691 OP 695 VO 18 IS 4 A1 G H Zoarski A1 H M Bear A1 J C Clouston A1 J Ragheb YR 1997 UL http://www.ajnr.org/content/18/4/691.abstract AB We describe two cases of coil malpositioning that occurred during endovascular occlusion of saccular basilar tip aneurysms with fibered platinum microcoils. The technique of endovascular coil extraction, accomplished successfully and without complication in both cases, is described and may be applicable to recently available controlled-detachment coil systems.
