“… 6 , 17 , 18 Initial treatment with clipping and coil embolization of the aneurysm alone is unlikely to be successful due to a failure to obliterate the diseased segment of the parent vessel, which can lead to recurrence. 12 , 19 In such cases, parent artery occlusion is a viable method to treat the entirety of the pathology and prevent aneurysm recurrence. 20 , 21 In this case, the aneurysm and parent vessel were occluded using coils, with the addition of Onyx embolic material to ensure occlusion of the parent vessel.…”

BACKGROUND Traumatic aneurysms are a rare sequela of nonaccidental head trauma in infants. The rate of nonaccidental trauma (NAT) in the pediatric population is increasing; therefore, traumatic aneurysms are an important consideration in the evaluation of pediatric patients with abusive head trauma. OBSERVATIONS A 24-day-old infant with no significant past medical or birth history presented with twitching and poor oral intake for 1 day. The patient was found to have bilateral subdural hematomas, multifocal contusions, and traumatic subarachnoid hemorrhage. NAT work-up was remarkable for a period of repeated and prolonged abuse. Magnetic resonance angiography revealed a right pericallosal traumatic aneurysm that was treated by means of coil and Onyx embolization. LESSONS Traumatic intracranial aneurysms are a rare but serious sequela of pediatric abusive trauma. Traumatic intracranial aneurysms should be considered in the setting of intracranial pathology associated with high-energy trauma. Despite new methods for the management of traumatic aneurysms, this pathology remains challenging to identify and treat, and the prognosis remains poor because of the diffuse injury often involved in these patients.

Background: Although endovascular parent artery occlusion (PAO) of the intracranial artery is a well-established treatment option, the long-term stability of cerebral blood flow remains a concern. This study aimed to evaluate the long-term clinical and radiological outcomes of patients who underwent PAO. Methods: The patients who underwent endovascular PAO of their internal carotid or vertebral artery (VA) between April 2011 and March 2022 were included in this observational study. Information about patient characteristics, details of the endovascular treatment, and clinical and radiological follow-up were collected. Results: The study included a total of 104 cases (average age 52.9±12.6 years old, male 73 (70.2%) cases, 95 (91.3%) VA PAO cases) from eight centers. Most cases were performed in an emergency condition, such as ruptured vertebral artery dissecting aneurysm (73 cases [70.2%]). PAO was successful in all cases. Early stroke (within 30 days) occurred in 33 (31.7%) cases (31 cases in VA PAO and two cases in internal carotid PAO) with ischemic stroke (29 cases) comprising the largest group. Clinical follow-up over 12 months was available in 78 cases. During an average follow-up period of 49.5 ± 24.3 months, one case in VA PAO experienced a stroke without functional deterioration. Imaging follow-up was performed in 73 cases. Recanalization of the occluded VA was observed in two cases. The remaining image change was contralateral VA stenosis after VA PAO. The incidence of clinical and radiological events was 0.95 and 1.1% per patient-year, respectively. Conclusions: Once the patients surpass the acute phase after PAO, their mid-to-long term course was stable. The risk of late stroke or de novo aneurysm formation was lower than expected in the literature, and the direct comparison to novel reconstructive techniques is warranted in future studies.
