Insights
Pre-operative coagulation analysis is crucial for chronic subdural hematoma surgery outcomes. Abnormal INR or thrombocytopenia significantly increases mortality risk in these patients.
Area of Science:
- Neurosurgery
- Hematology
Context:
- Chronic subdural hematoma (CSH) is a common intracranial hemorrhage.
- Retrospective analysis of 161 CSH patients operated between 1994-2000 at UNICAMP.
Purpose:
- Characterize the CSH patient population.
- Evaluate the impact of pre-operative coagulation status on surgical outcomes.
Summary:
- The majority of patients were male (86%), white (85.1%), with a median age of 57 years.
- Elevated INR (>1.25) and/or thrombocytopenia were associated with significantly higher postoperative mortality (p<0.001, p=0.004).
- A history of head injury correlated with lower mortality (p=0.044).
Impact:
- Highlights the critical role of pre-operative coagulation screening in CSH management.
- Suggests correcting coagulation abnormalities pre-surgery to improve patient outcomes.
- Informs surgical planning and risk stratification for intracranial hemorrhage patients.
Abstract:
The chronic subdural hematoma represents one of the most frequent types of intracranial hemorrhage. One hundred sixty one patients operated in the Clinical Hospital of State University of Campinas-SP (UNICAMP) from April 1994 to May 2000, were analyzed retrospectively in order to characterize the population and to study the importance of the pre-operative coagulation analysis in the outcome. The majority of the population was male (86%), white (85.1%) and in the fifth decade (median age: 57 years). A high mortality index in the postoperative period was found in patients with INR (international normalized ratio) values greater than 1.25 and/or thrombocytopenia (p<0.001 and p=0.004 respectively). Patients with previous head injury history (76%) showed a lower mortality (p=0.044). The results stand out the importance of the pre-operative evaluation with coagulation studies in order to correct possible abnormalities.
