OBJECTIVE: Traumatic brain injury (TBI) remains a major cause of morbidity and mortality worldwide. The prognostic value of skull fracture (SF) remains to be clearly defined. To evaluate the need for neurosurgical intervention and determine the risk factors of conservative treatment failure (CTF), we retrieved from the hospital database the records of patients with SF after TBI. METHODS: We analyzed 146 consecutive patients (mean age: 49.8 ± 17.5 years) treated at the department of neurosurgery in a 5-year period. Clinical data, radiologic reports, and laboratory results were evaluated retrospectively. RESULTS: A total of 63% of patients were treated conservatively, 21.9% were operated on immediately, and 15.1% experienced CTF. Overall, 73.3% had a favorable outcome; the mortality rate was 13%. Intracranial bleeding occurred in 96.6% of cases, basilar SF in 61%, and cerebrospinal fluid (CSF) leak in 2.8%. The independent risk factors for outcome were Glasgow Coma Scale (GCS) score, age, and platelet count (PCT). The independent risk factors for CTF were epidural hematoma, subdural hematoma, mass effect, edema, international normalized ratio, PCT, mean platelet volume, and CSF leakage. The consensus decision tree algorithm used at the accident and emergency department indicated patients with no need for neurosurgical intervention with an accuracy of 91.7%, sensitivity of 88.9%, and featured the importance of mass effect, GCS, and epidural hematoma. CONCLUSIONS: Tests included in the complete blood count appeared useful for predicting the course in patients with SF, although the most important factors were age and neurologic status, as well as radiologic findings. Our decision tree requires further validation before it can be used in everyday practice.

PRIMARY OBJECTIVE: To evaluate correlation between the lateral ventricle ratio (LVR) and the risk of conservative treatment failure (CTF) among patients with acute subdural hematoma (ASDH) after non-severe traumatic brain injury (TBI), we retrieved from the hospital database and performed a retrospective analysis of 1339 cases with TBI treated during the 2008-2016 period. METHODS AND PROCEDURES: 112 patients with ASDH, GCS≥ 9 and initial conservative treatment were enrolled. They were divided according to the final treatment method applied (surgical or conservative). Clinical and radiological data was evaluated. We used ROC curve analysis and multivariate logistic regression model to identify risk factors of CTF. MAIN OUTCOMES AND RESULTS: LVR higher than 1.48 calculated on admission CT scans was the strongest predictor of CTF, with sensitivity of 78.9% and specificity of 93.5% (AUC: 0.774-0.994). LVR, prolonged prothrombin time and coexisting traumatic subarachnoid hemorrhage were independent risk factors. CONCLUSIONS: Despite limitations, study results support the view that patients after non-severe TBI with ASDH and with lateral ventricle asymmetry, defined as LVR> 1.48, require surgical treatment. LVR seems to be indirect, but still the closest method to quantify intracranial compliance. Thus, in the selected group of patients without clinical symptoms of critically diminished compensatory reserve, LVR could indicate those who need a surgical decompression.
