Guglielmi Detachable Coil Extraction: Suction Generated by Pusher-Wire Withdrawal after Coil Detachment within an Intracranial Aneurysm

摘要

Summary: We present a case of Guglielmi detachable coil extraction into a microcatheter after coil detachment during embolization of a superior hypophyseal artery aneurysm; extraction was a result of the suction generated during pusher-wire withdrawal. Experimental simulations using many coil and microcatheter combinations were used to identify factors that contribute to the likelihood of this phenomenon.
