Abstract
Background: Since progressive intracranial haemorrhage (PIH) was introduced in neurosurgical literatures, several studies have been performed. PIH has been shown to be associated with a high increase in the risk of clinical worsening and related to morbidity and mortality as well. So, early detection and prediction of PIH is practically important in a clinical situation.
Objectves: To investigate the risk factors related to PIH in patients with acute traumatic brain injury (TBI) and analyse their clinical significances.
Methods: PIH was confirmed by comparing the first and repeated CT scans. Data compared included gender, age, mechanism of injury, Glasgow Coma Score (GCS) at admission, timing from injury to the first CT, the signs of the initial CT scan, prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fg), thrombin time (TT), platelet (PLT) and D-dimer (D-D) values. Logistic regression analysis was used to show the risk factors related to PIH.
Results: A cohort of 498 patients with TBI was evaluated, and there were 139 (27.91%) patients who suffered from PIH. The differences between PIHs and non-PIHs were significant in age, GCS at admission, the signs of the initial CT scan (fracture, subarachnoid haemorrhage, brain contusion and primary haematoma), PT, Fg and D-D values (p < 0.001). Logistic regression analysis was used to identify that CT scans (subarachnoid haemorrhage, brain contusion and primary haematoma) and plasma D-D values as the most important predictors of PIH (p < 0.001).
Conclusions: For patients with the initial CT scan showing subarachnoid haemorrhage, brain contusion and primary haematoma with abnormal D-D levels, an earlier and dynamic CT scan should be performed, for the detection of PIH as early as possible and the medical intervention would be enforced in time.
