All other admission variables and hospital complications, including admission H&H grade, aneurysm size of more than 1 cm, the presence of aneurysm rupture-associated intraparenchymal hematoma on admission head CT scan, probe location, hydrocephalus requiring cerebrospinal fluid diversion, and the aneurysm securing method, did not reveal significant differences in CMD-IL-6 levels. Here, IL6 is linked to Hydrocephalus.
