Clinical features and treatment of intracranial aneurysms in pediatric patients (with 9 case reports)

Abstract Objective To analyze the clinical characteristics, treatment, and prognosis of intracranial aneurysms in pediatrics Methods 9 pediatric patients (aged less than 18 years) with a diagnosis of intracranial aneurysm in the neurosurgical vascular group at our center from January 2015 to January 2022 are collected and their clinical data are analyzed retrospectively. We report the results of this study. Results In this group, there are 6 pediatric male patients and 3 pediatric female patients with intracranial aneurysms, of which 6 are anterior circulation aneurysms, 2 are posterior circulation aneurysms, and 1 is multiple aneurysms. There are 4 cases of the small aneurysm (diameter less than 1 cm), 4 cases of the large aneurysm (diameter 1.0-2.5 cm), and 1 case of a giant aneurysm (diameter more than 2.5 cm). 6 pediatric patients underwent craniotomy, and 3 pediatric patients underwent vascular intervention, there is no death in this group, 6 pediatric patients have a good prognosis (modified Rankin Scale (mRS) score 0-1), 3 pediatric patients have a mild disability The prognosis of 6 patients is good (modified Rankin Scale (mRS) score 0-1), and 3 patients have a mild impairment and other sequelae (modified Rankin Scale (mRS) score 2). Conclusion: The clinical features of intracranial aneurysms in pediatric patients are somewhat distinct from those seen in adults, and there is a need to develop individualized treatment plans regarding aneurysm site, size, character, and other global factors.
