The study identified two cases of patients who developed early cerebral amyloid angiopathy decades after pediatric cardiac surgery. Research suggests possible iatrogenic transfer of beta-amyloid during surgery. The use of cadaveric dura mater grafts may have contributed to amyloid transfer. The study highlights the need for further research into the potential risks associated with the use of biological materials in surgery. The findings suggest that pediatric surgery could have long-term neurological consequences. Researchers stress the importance of monitoring patients after surgery.
