The uncal hippocampal and anterior hippocampal-parahippocampal arteries contribute to the AHA complex, the posterior hippocampal-parahippocampal arteries serve as the MHA complex, and the PHA and splenial artery compose the PHA complex. Rich anastomoses between hippocampal arteries were observed, and in 11 (23%) hemispheres, anastomoses between each segment formed a complete vascular arcade at the hippocampal sulcus. Three veins were involved in hippocampal drainage\u2014the anterior hippocampal, anterior longitudinal hippocampal, and posterior longitudinal hippocampal veins\u2014which drain the hippocampal head, body, and tail, respectively, into the basal and internal cerebral veins.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>An understanding of the vascular variability and network of the hippocampus is essential for medial temporal tumor surgery via anterior temporal lobectomy with amygdalohippocampectomy and transsylvian selective amygdalohippocampectomy. Stereotactic procedures in this region should also consider the anatomy of the vascular arcade at the hippocampal sulcus.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2021.9.jns21390","type":"journal-article","created":{"date-parts":[[2022,1,7]],"date-time":"2022-01-07T16:19:35Z","timestamp":1641572375000},"page":"747-759","source":"Crossref","is-referenced-by-count":11,"title":["Microvascular anatomy of the medial temporal region"],"prefix":"10.3171","volume":"137","author":[{"given":"Yuanzhi","family":"Xu","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Huashan Hospital, Shanghai Medical College, Fudan University, Shanghai, China;"},{"name":"Department of Neurosurgery, Stanford Hospital, Stanford, California;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Mohyeldin","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Stanford Hospital, Stanford, California;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maximiliano Alberto","family":"Nunez","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Stanford Hospital, Stanford, California;"},{"name":"Department of Neurosurgery, Hospital El Cruce, Buenos Aires, Argentina;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayoze","family":"Doniz-Gonzalez","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Stanford Hospital, Stanford, California;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vera","family":"Vigo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Stanford Hospital, Stanford, California;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aaron A.","family":"Cohen-Gadol","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Indiana University, Indianapolis, Indiana; and"},{"name":"The Neurosurgical Atlas, Carmel, Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan C.","family":"Fernandez-Miranda","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Stanford Hospital, Stanford, California;"},{"name":"The Neurosurgical Atlas, Carmel, Indiana"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"5","key":"b1","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"339","DOI":"10.1016\/0090-3019(92)90001-4","article-title":"Microvascular anatomy of the hippocampal formation","volume":"37","author":"Marinkovi\u0107 S","year":"1992","unstructured":"Marinkovi\u0107 S, Milisavljevi\u0107 M, Pu\u0161ka\u0161 L.
