However, the efficacy of MT in the extended time window (6 to 24 h) is still uncertain. Our study aims to evaluate the outcomes of MT in the extended time window for AIS patients. Methods: We reviewed data on AIS patients who received MT beyond six hours of stroke onset from 2015 to 2022. The patients\u2019 occlusions were in the internal carotid artery (ICA), middle cerebral artery (MCA), or posterior circulation. Our evaluation included the modified Rankin scale (mRS) and 90-day mortality rates, as well as complications, such as symptomatic intracranial hemorrhage (sICH). Results: Thirty-one patients were included in this study, with a mean age of 75.6 \u00b1 15.1 years, of whom 54.8% were male. The median NIHSS score at presentation was 17. Successful recanalization (TICI 2b to 3) was achieved in 90.3% of patients and the rate of sICH was 6.4%. No difference was observed between the two age groups. The younger age group (&lt;80 years old) showed a better clinical outcome (mRS 0\u20132; p &lt; 0.05, Fisher\u2019s exact test) compared with the older age group. The overall mortality rate was 6.4%. Conclusion: Our study shows that (MT) can be performed effectively and safely within an extended time window, resulting in satisfactory functional outcomes, particularly in the younger age group.<\/jats:p>","DOI":"10.3390\/jpm14010002","type":"journal-article","created":{"date-parts":[[2023,12,19]],"date-time":"2023-12-19T11:17:24Z","timestamp":1702984644000},"page":"2","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Extended Time Window (&gt;6 Hour) Mechanical Thrombectomy; Good Clinical Outcome in the Younger Age Population in Thrombectomy Cases: Relationship between Age and Prognosis"],"prefix":"10.3390","volume":"14","author":[{"given":"Deok Un","family":"Gok","sequence":"first","affiliation":[{"name":"Depatment of Neurosurgery, International St. Mary\u2019s Hospital, Catholic Kwandong University, Incheon 22711, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"So Yeon","family":"Kim","sequence":"additional","affiliation":[{"name":"Depatment of Neurosurgery, International St. Mary\u2019s Hospital, Catholic Kwandong University, Incheon 22711, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young Chul","family":"Na","sequence":"additional","affiliation":[{"name":"Depatment of Neurosurgery, International St. Mary\u2019s Hospital, Catholic Kwandong University, Incheon 22711, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1192-8993","authenticated-orcid":false,"given":"Jin Mo","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Serim General Hospital, Incheon 21364, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11795735221098140","DOI":"10.1177\/11795735221098140","article-title":"Extended time window mechanical thrombectomy for pediatric acute ischemic stroke","volume":"14","year":"2022","journal-title":"J.
