Proximal occlusion of PCA represents a treatment option for these lesions. However, this procedure carries a high risk of ischemic complications.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>OBJECTIVE:<\/jats:bold>\n                    To describe the technique of trapping a fusiform PCA aneurysm and revascularization of the distal PCA using a superficial temporal artery (STA) graft through the same microsurgical approach.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>METHODS:<\/jats:bold>\n                    From September 2012 to October 2014, we retrospectively identified 3 patients harboring a fusiform PCA aneurysm (P2 segment aneurysm) who underwent trapping of the aneurysm and reconstruction of the distal PCA through the same subtemporal approach. We analyzed immediate morbidity, surgical complications, and the patency of the bypass to determine the feasibility of this procedure.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>RESULTS:<\/jats:bold>\n                    All 3 patients underwent successful trapping of the fusiform PCA aneurysm and revascularization of the distal PCA. The origin of P3 segment or posterior temporal artery (PTA) served as recipient arteries. In all 3 cases, adequate blood flow was evident after performing the STA-P3\/PTA bypass. None of the patients experienced a new permanent neurological deficit. At 1-year follow-up, the STA-PTA\/PCA bypasses remained patent.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>CONCLUSION:<\/jats:bold>\n                    The STA-P3\/PTA bypass through the subtemporal approach is a feasible option to maintain blood flow in cases of PCA fusiform aneurysms requiring trapping of the P2 segment.\n                  <\/jats:p>","DOI":"10.1093\/ons\/opw033","type":"journal-article","created":{"date-parts":[[2017,2,3]],"date-time":"2017-02-03T18:10:27Z","timestamp":1486145427000},"page":"309-316","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":16,"title":["Superficial Temporal Artery: Distal Posterior Cerebral Artery Bypass through the Subtemporal Approach: Technical Note and Pilot Surgical Cases"],"prefix":"10.1227","volume":"13","author":[{"given":"Akitsugu","family":"Kawashima","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Tokyo Women's Medical University Yachiyo Medical Center, Chiba, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hugo","family":"Andrade-Barazarte","sequence":"additional","affiliation":[{"name":"Depart-ment of Neurosurgery, University of Helsinki and Helsinki University Hospital, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Behnam Rezai","family":"Jahromi","sequence":"additional","affiliation":[{"name":"Depart-ment of Neurosurgery, University of Helsinki and Helsinki University Hospital, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minna","family":"Oinas","sequence":"additional","affiliation":[{"name":"Depart-ment of Neurosurgery, University of Helsinki and Helsinki University Hospital, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Elsharkawy","sequence":"additional","affiliation":[{"name":"Department of Neu-rosurgery, Tanta University, Tanta, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juri","family":"Kivelev","sequence":"additional","affiliation":[{"name":"Depart-ment of Neurosurgery, University of Helsinki and Helsinki University Hospital, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuichi","family":"Kubota","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Asakadai Central Hospital, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takakazu","family":"Kawamata","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tokyo Women's Medical University, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juha A.","family":"Hernesniemi","sequence":"additional","affiliation":[{"name":"Depart-ment of Neurosurgery, University of Helsinki and Helsinki University Hospital, Helsinki, Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2017,6]]},"reference":[{"issue":"2","key":"bib1-20240909","doi-asserted-by":"crossref","first-page":"141","DOI":"10.3171\/jns.1997.87.2.0141","article-title":"Giant fusiform intracranial aneurysms: review of 120 patients treated surgically from 1965 to 1992","volume":"87","author":"Drake","year":"1997","journal-title":"J Neurosurg"},{"issue":"2","key":"bib2-20240909","doi-asserted-by":"crossref","first-page":"134","DOI":"10.1227\/NEU.0000000000000363","article-title":"Characteristics of posterior cerebral artery aneurysms: an angiographic analysis of 93 aneurysms in 81 patients","volume":"75","author":"Goehre","year":"2014","journal-title":"Neurosurgery"},{"issue":"24","key":"bib3-20240909","doi-asserted-by":"crossref","first-page":"1725","DOI":"10.1056\/NEJM199812103392401","article-title":"Unruptured intracranial aneurysms\u2014risk of rupture and risks of surgical intervention.
