He was eventually found to harbor a giant, partially thrombosed, saccular aneurysm arising from the A1\/A2 segment of the right anterior cerebral artery with foramen of Monro obstruction and a trapped left-sided ventricular system. An azygous left A2 artery segment supplied both callosomarginal arteries. We performed an in situ side-to-side anastomosis between the distal left azygous anterior cerebral artery and the right pericallosal artery, which was previously supplied by the right A1. The right A1 was clip ligated, and the aneurysm evacuated with an ultrasonic aspirator. Postoperatively, the patient did well with no recurrence of the aneurysm and resolution of his preoperative obstructive hydrocephalus. He continues to be independent\u00a0&gt;7 yr post surgery. His 6-mo follow-up angiogram revealed a patent bypass.<\/jats:p>","DOI":"10.1093\/ons\/opy110","type":"journal-article","created":{"date-parts":[[2018,5,12]],"date-time":"2018-05-12T05:15:35Z","timestamp":1526102135000},"page":"E81-E82","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["In Situ Left Azygous Anterior Cerebral Artery to Right Pericallosal Artery Bypass for Treatment of a Giant Right A1\/2 Aneurysm: 2-Dimensional Operative Video"],"prefix":"10.1227","volume":"15","author":[{"given":"Gary","family":"Rajah","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Wayne State University, Detroit, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Hoeprich","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kettering Health Network, Dayton, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Narayanan","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Wayne State University, Detroit, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Murali","family":"Guthikonda","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Wayne State University, Detroit, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandeep","family":"Mittal","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Wayne State University, Detroit, Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2018,12]]},"container-title":["Operative Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/ons\/article-pdf\/15\/6\/E81\/30208113\/opy110.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/www.ovid.com\/01787389-201812000-00023","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T16:46:09Z","timestamp":1786121169000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/01787389-201812000-00023"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,5,12]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2018]]}},"URL":"https:\/\/doi.org\/10.1093\/ons\/opy110","relation":{},"ISSN":["2332-4252","2332-4260"],"issn-type":[{"value":"2332-4252","type":"print"},{"value":"2332-4260","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,5,12]]},"assertion":[{"value":"2017-12-20","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-04-11","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
