Abstract |
Objective Decompressive craniectomy (DC) has been the most chosen operative technique for decreasing the intracranial pressure in patients
with acute subdural hematoma. Yet, DC has some severe complications such as delayed traumatic intracerebral hemorrhage (DT-ICH). This
study investigated the variable factors which may cause DT-ICH post-operatively.
Methods We retrospectively reviewed 72 acute SDH patients above 60 year-old whom underwent DC at our institution between January
2010 and January 2012. All patients were analyzed based on the information acquired from the pre-operative clinical factors (gender, past
history, cause of injury, aspartate aminotransferase (AST) / alanine transaminase (ALT), prothrombin time (PT), international normalized ratio
(INR), platelet count, presence of contusional hemorrhage at preoperative computed tomography (CT), thickness of hematoma, degree of midline
shift and, compression ratio (midline shift/hematoma thickness)). Immediate post-operative CT scan was carried out in all patients. Then, the
relationship between each parameter and presence of DT-ICH after DC was analyzed statistically.
Results Out of 72 SDH elderly patients, DT-ICH occurred in 26 patients (36%) while the rest of 46 patients (64%) had no further hemorrhagic
event. Of many variable factors to cause DT-ICH, male, low platelet count, INR prolongation, PT prolongation, presence of contusional hemorrhage,
hematoma thickness and compression ratio showed a statistically significance in univariate analysis (p<0.05). Whereas in multivariate
analysis, low platelet count, INR prolongation, thicker hematoma and low compression ratio demonstrated a statistically significance (p<0.05).
Conclusion According to our study, patients with low compression ratio had a higher tendency of DT-ICH after DC. This information can
be crucial in predicting the possibility of DT-ICH in higher risk elderly patients. |
