Abstract
ObjectiveTo explore the clinical factors of the brain rebound speed after drainage in patients with chronic subdural hematomas.
MethodsThe clinical and imaging data of 90 adult patients with chronic subdural hematomas were retrospectively reviewed who were treated at Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University from January 2015 to December 2016. Those data analyzed included the patient's age, gender, maximal diameter of the hematoma, maximal anteroposterior diameter of the skull, and maximal distance between the brain and the inner edge of the skull. The correlation between clinical factors and the velocity of brain tissue recovery was analyzed.
ResultsThe postoperative brain rebound speed was significantly higher in the younger age group (<40 years) than in the older age group (>80 years) (P=0.008), and it was significantly higher in patients with small hematomas (<100 mm) than in those cases with larger hematomas (140-150 mm) (P<0.05). In addition, this study suggested a negative correlation between relative brain tissue recovery and the longest diameter of the skull (P=0.027). Gender, the maximal width of initial hematoma, maximal area of initial hematoma were not associated with the postoperative brain rebound speed (all P>0.05).
ConclusionThe brain rebound speed in patients with chronic subdural hematomas seemed to be related to age, the longest diameter of initial hematoma and maximal anteroposterior diameter of the skull.
