Then, the DDR is cut around the dorsal part of the carotid artery, moving toward the dura covering the optic nerve (ON). After, the lateral and ventral part of the ring is cut until the artery is freed from the dural attachment. The space between the proximal and DDR is visible and can be used as a proximal vascular control site if needed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Microsurgical clipping of paraclinoid aneurysms through a pterional or a keyhole approach, combined with a systematic technique for opening the carotid rings, is an excellent strategy for exposing and clipping paraclinoid aneurysms, yielding favorable clinical and surgical outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00701-025-06673-7","type":"journal-article","created":{"date-parts":[[2025,10,27]],"date-time":"2025-10-27T07:44:24Z","timestamp":1761551064000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Microsurgical opening of the carotid dural rings: how I do it"],"prefix":"10.1007","volume":"167","author":[{"given":"Edgar","family":"Nathal","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandro","family":"Serrano Rubio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharon","family":"Trujillo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodolfo","family":"Villalobos-D\u00edaz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juli\u00e1n Mois\u00e9s","family":"Enr\u00edquez-\u00c1lvarez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,10,27]]},"reference":[{"issue":"1","key":"6673_CR1","doi-asserted-by":"publisher","first-page":"3","DOI":"10.1002\/ca.20053","volume":"18","author":"F Collignon","year":"2005","unstructured":"Collignon F, Link M (2005) Paraclinoid and cavernous sinus regions: measurement of critical structures relevant for surgical procedure.
