Solitaire? stent for endovascular coil retrieval.

摘要

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.
