The techniques used for clipping various aneurysms are based upon their subtypes and location. In the first case, in a giant superior hypophyseal artery aneurysm directed toward the suprasellar region, an intradural clinoidectomy helped in accessing the neck of the aneurysm encroaching into the clinoidal segment of ICA. In the second case, concurrent bilateral \u201ckissing\u201d paraclinoid segment aneurysms were clipped using a unilateral approach. In the third case, clipping of a dissecting paraclinoid segment aneurysm is demonstrated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Surgery still represents the most definitive form of treatment. It may also be used to evacuate an intracerebral hematoma, with an extremely tortuous proximal vessel or in an aneurysm with complex anatomy, with blister aneurysms, or following aneurysm regrowth following a failed endovascular procedure. Assessing the three-dimensional anatomy of various segments of ICA is an important step.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/0028-3886.329547","type":"journal-article","created":{"date-parts":[[2024,9,7]],"date-time":"2024-09-07T15:08:31Z","timestamp":1725721711000},"page":"1184-1195","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":6,"title":["Paraclinoid Segment Aneurysms of the Internal Carotid Artery: Surgical Clipping"],"prefix":"10.4103","volume":"69","author":[{"given":"Sanjay","family":"Behari","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priyadarshi","family":"Dikshit","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suyash","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gagandeep","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vivek","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Radiology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajendra V","family":"Phadke","sequence":"additional","affiliation":[{"name":"Department of Radiology, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kamlesh S","family":"Bhaisora","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2021,10,30]]},"reference":[{"key":"R2-20250925","first-page":"425","article-title":"Segments of the internal carotid artery: A new classification","volume":"38","author":"Bouthillier","year":"1996","journal-title":"Neurosurgery"},{"key":"R3-20250925","first-page":"483","article-title":"Fronto-temporal craniotomy with zygomatic osteotomy for a clinoidal meningioma.
