Abstract

Objective Cerebral vasospasm (VS) is one of the factors that can most significantly worsen the prognosis after aneurysmal subarachnoid hemorrhage (SAH). A substantial body of evidence supports the idea that CSF diversion could prevent VS, even if this issue is still much debated. External ventricular drainage (EVD) is the recommended procedure for post-hemorrhagic hydrocephalus. In this study we analyzed whether EVD, placed for acute hydrocephalus, is effective in reducing the incidence of clinical and radiological cerebral vasospasm in patients who underwent endovascular treatment for aneurysmal SAH. Patients and methods We retrospectively studied the incidence of radiologically confirmed VS in 141 patients treated endovascularly for aneurysmal SAH: 80 underwent EVD for hydrocephalus, 61 did not undergo EVD. Results VS occurred in 8.75% of cases (7 patients) in the first groups, while in 22.95% (14 patients) in the second group. In addition, patients not treated with EVD display a prevalence of VS in lower Fisher grades compared to the other group. Conclusion Our data indicate that CSF drainage reduces the risk of vasospasms in patients with endovascular treatment for aneurysmal SAH.
