This pattern of white matter injury is known to portend poor neurodevelopmental outcomes, but the exact aetiology and histologic characterisation of these lesions have never been described. A fetal sheep was cannulated at gestational age 110\u00a0days onto a pumpless extracorporeal oxygenator via the umbilical vessels and supported in a fluid environment for 14.5\u00a0days. The fetus was supported under hypoxic conditions (mean oxygen delivery 16\u00a0ml\/kg\/day) to simulate the <jats:italic>in\u00a0utero<\/jats:italic> conditions of CHD. At necropsy, the brain was fixed, imaged with MRI, and then stained to histologically identify areas of injury. Under hypoxemic <jats:italic>in\u00a0utero<\/jats:italic> conditions, the fetus developed a T1 hyperintense lesion in its right frontal lobe. Histologically, this lesion was characterised by microvascular proliferation and astrocytosis without gliosis. These findings may provide valuable insight into the aetiology of white matter injury in neonates with CHD.<\/jats:p>","DOI":"10.1017\/s104795112200107x","type":"journal-article","created":{"date-parts":[[2022,4,19]],"date-time":"2022-04-19T10:52:13Z","timestamp":1650365533000},"page":"432-436","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":2,"title":["Radiographic and histologic characterisation of white matter injury in a sheep model of CHD"],"prefix":"10.1017","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2698-5720","authenticated-orcid":false,"given":"Kendall M.","family":"Lawrence","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrico","family":"Radaelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick E.","family":"McGovern","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel J.","family":"Licht","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcus G.","family":"Davey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan W.","family":"Flake","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
