Although many Japanese neurosurgeons can perform surgical clipping of middle cerebral artery aneurysms or internal carotid artery\u2014posterior communicating artery aneurysms and coil embolization of cerebral aneurysms using simple techniques\u2014only a limited number of neurosurgeons are able to perform surgical clipping and endovascular procedures for anterior communicating artery aneurysms, paraclinoid, or posterior circulation aneurysms using both treatment modalities equally and safely. Materials and methods: The senior author\u2019s personal experience of more than 500 cases each of surgical clipping and endovascular embolization over the past 25\u00a0years included 110 cases of basilar tip aneurysms and 104 cases of paraclinoid internal carotid artery (ICA) aneurysms. Results: The safety and efficacy of both treatments appears to be the same, while the durability of surgical clipping is superior to that of endovascular embolization. Among the 110 basilar tip aneurysms, 18 patients were treated by surgical clipping and 94 were treated by endovascular embolization. The initial results of endovascular therapy seemed to be better than those of surgical clipping, although the rate of retreatment was higher. Among the 104 cases of paraclinoid ICA aneurysm, 23 patients were treated by surgical clipping and 81 were treated by endovascular embolization. The results of both treatments seemed to be same, while surgical clipping had apparently good long-term durability. Over the past 15\u00a0years, the frequency of surgical clipping for basilar tip aneurysms has decreased, and the procedure may eventually be abandoned for this type of aneurysm. However, surgical clipping still offers several advantages in the treatment of paraclinoid aneurysms. Conclusions: Hybrid neurosurgeons can make reasonable decisions concerning the choice of treatment for cerebral aneurysms, as they perform both treatments and understand the benefits and drawbacks of each modality.<\/jats:p>","DOI":"10.1007\/978-3-030-63453-7_21","type":"book-chapter","created":{"date-parts":[[2021,6,2]],"date-time":"2021-06-02T18:11:31Z","timestamp":1622657491000},"page":"145-149","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Hybrid Neurosurgeon: The Japanese Experience"],"prefix":"10.1007","author":[{"given":"Yasuhiko","family":"Kaku","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takumi","family":"Yamada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shouji","family":"Yasuda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiyomitsu","family":"Kanou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoki","family":"Oka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jouji","family":"Kokuzawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,5,11]]},"reference":[{"issue":"Suppl 1","key":"21_CR1","doi-asserted-by":"publisher","first-page":"89","DOI":"10.1177\/15910199990050S116","volume":"5","author":"Y Kaku","year":"1999","unstructured":"Kaku Y, Yoshimura S, Hayashi K, Ueda T, Sakai N (1999) Follow up study on intra-aneurysmal embolization for unruptured cerebral aneurysms.
