    Abstract:
    OBJECTIVES: The optimal surgical procedure for long-standing overt ventriculomegaly in adults (LOVA) remains controversial. METHODS: A systematic search of three databases was performed for studies published between January 1999 and March 2022. This systematic review included 12 studies with a total of 318 patients with LOVA surgically treated. PRISMA guidelines were followed. RESULTS: Gait disturbance (74.8%) and headache (59.7%) were the most common clinical presentation. Overall, the rate of postoperative clinical improvement at the last follow-up was 83.6% (95% CI 78.1-86.1). A lower rate of postoperative clinical improvement or halt of progression of presenting symptoms was observed after ETV (211/257 = 82.1% 95% CI 76.2-85.1%) compared with VPS (55/61 = 90.2% 95% CI 80.3-96.1%). Overall, surgical and postoperative complications were reported in 22/297 patients (7.5% 95% CI 4.4-20%) (11 studies). A higher rate of surgical complications was observed in patients treated with VPS (19.7% 95 CI 5.9-46.7%), compared with patients treated with ETV (4.3% 95% CI 2.1-10.9%). The overall rate of second surgery due to failure of first surgical approach (ETV or VPS) was 46/275 (16.7%). DISCUSSION: This meta-analysis confirmed the efficacy of EVT and VPS in symptomatic patients with LOVA, reporting a roughly 84% of postoperative clinical improvement or halt of progression of symptoms. A higher rate of surgical complications was observed in patients treated with VPS compared with patients treated with ETV. In addition, roughly 18% of patients treated with ETV required a further VPS. These findings should be considered when advising LOVA patients regarding the management of hydrocephalus.
