Successful WEBectomy during embolization of temporal arteriovenous malformation-associated flow-related basilar aneurysms.

OBJECTIVE Intra-procedural WEB device migration is a scarcely reported complication that necessitates prompt intervention. CASE PRESENTATION Endovascular treatment of two broad necked flow-related aneurysms was planned aided by WEB-SL (Woven EndoBridge-single layer) devices in a 71-year-old female with known left temporal arteriovenous malformation. Inadvertent distal migration occurred while performing a control angiogram with an automated iodine injector. Immediate retrieval was successfully performed using a Solitaire stent-retriever. CONCLUSION To our knowledge, we report for the first time the successful retrieval of a distally migrated WEB using a stent-retriever device.
