Solitaire® stent for endovascular coil retrieval.

Abstract

Coil migration during embolization is an emergency, requiring individual solutions. A 71-year-old female patient was referred to our hospital suffering from subarachnoid hemorrhage due to a ruptured giant aneurysm of the ophthalmic segment of the right internal carotid artery (ICA). During the endovascular procedure, a coil migrated in the ICA. Coil dislocation could be treated by either retrieval or fixation. On intention to treat we retrieved the coil with the self-expanding Solitaire(®) AB stent (Ev3, Irvine, CA, USA). The Solitaire(®) stent is established to perform mechanical thrombectomy for treatment of acute stroke. This report demonstrates the Solitaire(®) stent's potential for safe and effective retrieval of dislocated coils. Other retrieval systems will be discussed.
