Abstract: Pediatric chronic subdural effusion (PCE) is a prevalent neurosurgical condition in children,particularly among infants and young children.Classified into traumatic,infectious,and idiopathic types,it manifests clinically from asymptomatic to varying degrees of intracranial hypertension and neurological deficits.This systematic review examines diagnostic approaches,therapeutic strategies,and prognosis assessment for PCE,with particular focus on comparing conservative management versus surgical interventions (including burr hole drainage,subdural-abdominal shunt,and craniotomy) in terms of indications,technical nuances,and efficacy.Emerging modalities such as immunotherapy are also explored.

Key words: children, chronic subdural effusion, burr hole drainage, shunt surgery, immunotherapy, prognosis
