Long-standing overt ventriculomegaly in adults (LOVA) is a type of hydrocephalus that develops during childhood and manifests symptoms in adulthood, with controversies still existing. By collecting a series of symptomatic LOVA patients successfully treated with ETV, it was found that ETV has achieved rewarding results in neurological and neurocognitive outcomes.
OBJECTIVE: Long-standing overt ventriculomegaly in adults (LOVA) is form of hydrocephalus that develops during childhood, manifesting its symptoms during adulthood. Only a small number of LOVA case series have been published, and controversies regarding optimal management still exist. The authors collected a series of symptomatic LOVA patients treated successfully using endoscopic third ventriculostomy (ETV), aiming to strengthen what has been reported in the literature on ETV's role in both neurologic and neurocognitive outcomes. METHODS: Between 2002 and 2020, we collected 40 case studies of patients treated using an ETV. Associated pathologies were documented in 14 cases. All patients underwent magnetic resonance scans preoperatively and postoperatively while only 29 patients were submitted during follow-up to neurocognitive assessment. -RESULT: At a mean follow-up of 6 years, 36 patients (90%) reported either an improvement or a stabilization of their presenting symptoms. Headache improved subjectively in 11 patients (27.5%), balance and gait disturbances improved in all patients, urinary incontinence improved in 24 patients (60%), memory disturbances subjectively improved in 21 patients (52.5%), and visual deficits improved in 5 patients (12.5%). Four patients (10%) had symptom progression, which occurred 6 to 24 months after surgery with radiologic evidence of ETV failure. -CONCLUSIONS: LOVA is a form of hydrocephalus that must be correctly identified. A correct magnetic resonance study and comprehensive neuropsychologic assessment are crucial to identify it in order to define proper management. From our analysis, ETV represents the gold standard treatment granting rewarding results that are maintained in a long-term follow-up.
