A Case Report Using Goose Neck Microsnare for Severe Cervical Internal Carotid Artery Occlusion with Dolichoarteriopathy.

Objective: We report the use of a Goose Neck microsnare for cervical internal carotid artery (ICA) occlusion in a patient with dolichoarteriopathy in whom it was difficult to achieve recanalization.

Case Presentation: A 65-year-old woman underwent thrombectomy for a tandem lesion of left M1 occlusion and left cervical ICA occlusion. Recanalization of left M1 occlusion was achieved. For left cervical ICA occlusion, we attempted multiple thrombectomy using an existing device, but a hard clot with mobility was caught due to dolichoarteriopathy, which made thrombectomy difficult. Using a Goose Neck microsnare, we were able to capture the thrombus and achieve recanalization.

Conclusion: Thrombectomy by capturing the thrombus using a Goose Neck microsnare may be useful for capturing hard clots with mobility when it is difficult to achieve recanalization with existing devices.
