Objective: In patients suffering from ruptured or unruptured brain arteriovenous malformations (AVM), data on possible shunt-dependent hydrocephalus with subsequent ventriculo-peritoneal shunt (VPS) placement is scarce. We therefore analyzed our institutional data to identify risk factors determining a shunt-dependency in patients with AVM.
Methods: From 2009 to 2016, 99 patients with ruptured or unruptured AVM were admitted to the authors’ institution. Patient characteristics, radiological features, clinical symptoms, treatment modality, location and size of AVM, functional outcome, and presence of VPS were assessed and analyzed.
Results: Overall, 41% of AVM patients presented with AVM-related hemorrhage. VPS implantation due to shunt-dependent hydrocephalus was necessary in 6 out of 99 patients (6%). Shunt-dependency was associated with AVM-related hemorrhage (p=0.004) and AVM location in the posterior fossa (p=0.0003).
Conclusion: The present data suggests that shunt-dependent hydrocephalus is rare in patients with AVM. However, location of AVM and the presence of AVM-related hemorrhage are significantly associated with development of shunt-dependency in patients with AVM throughout the treatment course.
