Posterior circulation aneurysms in young people

Intracranial Aneurysms in Childhood: 27-Year Single-Institution Experience

“…8 Aneurysms in this population exhibit features that differ significantly from those in adults, including male predominance, a higher incidence of unusual anatomic locations such as the posterior circulation and internal carotid bifurcation, and greater numbers of giant aneurysms. 1,[9][10][11][12] Moreover, although some risk factors for the formation of intracranial aneurysms have been identified in adults (family history, age older than 50 years, smoking, cocaine use, and hypertension), in childhood most of these risk factors do not exist. [13][14][15][16] In this context, some authors have advanced the concept of an aneurysmal vasculopathy involving vulnerable segments of the arterial tree.…”

“…Good outcomes have been reported to range from 40% to 95% in the surgical literature. 2,7,10,11,[20][21][22][23] This heterogeneity in outcomes represents patients treated during the course of a half century, with considerable heterogeneity in patient characteristics, lesion characteristics, and operative technique. On the other hand, scientific literature pertaining to the endovascular management of aneurysms in childhood remains limited.…”

Fusiform P1 Segment Artery Aneurysm in a Pediatric Patient: Technical Case Report

“…Cerebral aneurysms in children most commonly occur in the setting of cerebral trauma or infections [1,2,[5][6][7][8][9]. Pediatric aneurysms also differ in location, size and morphology when compared to their adult counterparts, and several authors report a reverse male to female ratio as compared to adults [1,2,10].…”

“…Cerebral aneurysms in children most commonly occur in the setting of cerebral trauma or infections [1,2,[5][6][7][8][9]. Pediatric aneurysms also differ in location, size and morphology when compared to their adult counterparts, and several authors report a reverse male to female ratio as compared to adults [1,2,10]. In addition to the fusiform configuration of this aneurysm, posterior cerebral artery aneurysms are by themselves unusual and difficult to treat lesions [3,11]; the small size of this patient made it impossible to physically fit an aneurysm clip and applier through any available route of approach.…”

“…Pediatric intracranial aneurysms are a rare entity, and those in the posterior circulation are even more unusual [1][2][3]. A recent literature review found a total of 54 aneurysms reported in children ^1 year of age [3].…”
