,95 A peak value of IL-6 above 10,000 pg/ml was also correlated with a higher incidence of shunt-related hydrocephalus (p = 0.009), with other risk factors such as aneurysm location on the anterior cerebral artery and its branches or in the posterior circulation (p = 0.025), and age ≥60 years (p = 0.014).96 The gene discussed is IL6; the disease is Hydrocephalus.
