[Three cases of mechanical thrombectomy in patients over 100 years old].

Background: While several cases involving mechanical thrombectomy in patients >90 years old have been reported, only 1 case involving a patient >100 years old has been described. We herein report 3 cases of mechanical thrombectomy performed in patients >100 years old, along with a review of the literature.Case 1: A 102-year-old woman with a National Institute of Health Stroke Scale (NIHSS) score of 20 and diffusion weighted imaging (DWI)-Alberta Stroke Program Early Computed Tomography Score (ASPECTS) of 8 points showed M1 occlusion. She was treated with tissue plasminogen activator followed by mechanical thrombectomy. Recanalization of thrombosis in cerebral infarction (TICI)-3 was obtained at 1 pass. After 90 days, her modified Rankin Scale (mRS) was 2, and she returned to living independently.Case 2: A 104-year-old woman with a NIHSS score of 13 and DWI-ASPECTS of 9 points showed M1 occlusion, so mechanical thrombectomy was performed. Recanalization of TICI-3 was obtained. She was admitted with an mRS of 5.Case 3: A 101-year-old woman with an NIHSS score of 8 and DWI-ASPECTS of 10 points showed right internal carotid artery occlusion, so mechanical thrombectomy was performed. Direct puncture of the right common carotid artery was performed due to access difficulties. Recanalization of TICI-3 was obtained. She was admitted with an mRS of 5.

Conclusion: In all cases, occlusion access using techniques such as direct carotid puncture was possible, but two of the three patients had an mRS of 5, resulting in a poor prognosis. The indication for treatment in patients >100 years old should be carefully considered.
