|Issue Date:||2022||metadata.dc.date:||2022||Publication information:||Stroke 2022-08; 53(8): e369-e374||Abstract:||Recent reports raise the possibility of cerebral amyloid angiopathy (CAA) leading to intracerebral hemorrhage in young adults following childhood neurosurgery, suggesting transmission of amyloid-β (Aβ) through neurosurgical procedures including dura mater grafting. Parenchymal Aβ deposition, and to a lesser extent tau aggregation, similar to that seen in Alzheimer disease, have also been described. We conducted a database review of 634 consecutive intracerebral hemorrhage patients aged <65 years at a tertiary stroke center over 20 years to identify such patients. We identified 3 patients aged in their thirties who presented with spontaneous lobar intracerebral hemorrhage, with imaging or neuropathology consistent with CAA, and a history of childhood neurosurgery. Two of these patients had undergone a dural repair using cadaveric dura mater (Lyodura). In addition to CAA, both patients had neuropathologically confirmed parenchymal Aβ and tau deposits, characteristic of Alzheimer disease. Our findings support the concept of neurosurgical Aβ transmission but suggest that such cases are rare in standard clinical practice.||URI:||https://ahro.austin.org.au/austinjspui/handle/1/30483||DOI:||10.1161/STROKEAHA.121.038364||ORCID:||0000-0001-9786-3096
