Background: Some centers utilize ventriculopleural shunt (VPLS) for treating hydrocephalus when conventional approaches are not feasible. Nonetheless, the literature regarding this approach is scarce.
Purpose: Evaluate the outcomes of VPLS through a single-arm meta-analysis.
Methods: Following PRISMA guidelines, the authors systematically searched for articles utilizing the VPLS in a cohort with more than four patients. Outcomes included: mortality, pleural effusion, number of patients who underwent revisions, obstructions, shunt migration, emphysema, and subdural hematoma.
Results: A total of 404 articles were reviewed, resulting in the inclusion of 13 retrospective studies encompassing 543 patients, with the majority being children (62.6 %). The median average follow-up period was 35.4 months (10-64.1). After analysis, results yielded a revision rate of 54 % (95 % CI: 44 %-64 %; I2=73 %). The most common complication observed was pleural effusion, with a post-analysis incidence of 16 % (95 % CI: 11 %-21 %; I2=63 %), followed by infections at 7 % (95 % CI: 4 %-10 %; I2=33 %). Shunt obstruction occurred in 13 % (95 % CI: 4 %-21 %; I2=84 %) of cases after analysis, while migrations, overdrainage, subdural hematoma, and cutaneous emphysema had minimal occurrence rates (0 %, 95 % CI: 0 %-1 %; I2=0 %). Notably, there were no reported cases of shunt-related mortality.
Conclusion: VPLS can be considered when there are no other suitable options for placing the distal catheter. However, the notable rates of shunt revisions, pleural effusion, infections, and the inherent heterogeneity of outcomes currently limit the widespread adoption of VPLS. In this scenario, other alternatives should be given priority.
