However, few reports have described microguidewires (MGWs) becoming entrapped. Case Description: An 83-year-old man with a history of cancer in the pancreatic head developed a disturbance of consciousness and left hemiplegia. Mechanical thrombectomy was performed for occlusion of the right posterior cerebral artery. The occluded lesion was passed using an MGW with a straight tip. The MGW became impossible to move after advancing into the perforator distal to the occluding thrombus. The MGW was removed using a goose-neck snare under general anesthesia. A small amount of subarachnoid hemorrhage occurred after wire removal but did not affect the clinical course. Conclusion: MGW entrapment is a rare complication in neuroendovascular therapy, particularly in mechanical thrombectomy. Removal of an entrapped MGW is associated with a risk of hemorrhagic complications. If the thrombus is hard and a J-shaped wire cannot be passed, the risk of MGW entrapment is high.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/573f6f4b-4bf8-45dc-875c-90fa416343c0/featured/hero-1781558756580.png","publishDate":"2025-04-04T00:00:00.000Z","doi":"10.25259/SNI_193_2025","categories":["Neurovascular","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2025/04/13480/SNI-16-126.pdf"}
