Insights
Chronic subdural hematoma (CSH) primarily affects elderly patients. Prognosis depends on age and comorbidities, not hematoma size, with higher risks in multi-morbid individuals.
Area of Science:
- Neurosurgery
- Geriatrics
- Internal Medicine
Context:
- Chronic subdural hematoma (CSH) is a significant neurological condition predominantly affecting individuals over 50.
- Standard treatment involves burr hole trephination and subdural drainage, a procedure with reported lethality rates up to 20%.
Purpose:
- To analyze the impact of complicating diseases and patient age on the prognosis of chronic subdural hematoma.
- To evaluate neurological outcomes using the Bender scale before and after surgical intervention.
Summary:
- A study of 314 CSH patients revealed high prevalence of comorbidities like cardiological diseases (14.3%), anticoagulant use (6.7%), alcoholism (15.9%), and hypertension (12.8%).
- Over half of patients (51.3%) had complicating diseases, which, along with age, significantly influenced prognosis more than hematoma thickness or midline shift.
- Comorbidities were associated with increased post-trephination complications including infection, secondary hemorrhages, pneumonia, and seizures.
Impact:
- Prognosis and post-operative outcomes in CSH are critically determined by patient age and the presence of multiple comorbidities, particularly diabetes mellitus, cardiogenic diseases, and hypertension.
- Elderly and multi-morbid patients face a higher risk of mortality and poorer outcomes following CSH treatment.
- Findings underscore the importance of managing comorbidities in elderly patients with chronic subdural hematoma to improve surgical outcomes.
Abstract:
The chronic subdural hematoma (CSH) is a disease in elderly patients beyond the 5th decade. Treatment of CSH is normally a burr hole trephination and subdural drainage. Although this technique is simple, lethality is reported to be up to 20% in literature. The records of 314 patients with CSH were analyzed. Attention was focussed on complicating diseases and distribution of age. Patients were categorized neurologically before and after trephination using the Bender scale. The portion of patients suffering from cardiological diseases was 14.3%, 6.7% were treated by anticoagulants because of cardiac valve implant. Alcoholics were found in 15.9% of patients and hypertension in 12.8%. Complicating diseases were found in 51.3% of patients. Multiple internal diseases are likely to affect prognosis more than hematoma thickness. These patients also brought about a higher rate of infection (4.8%), secondary hemorrhages (2.5%), pneumonia (3%) and seizures (5%) after trephination. Lethality was highest in patients with diabetes mellitus, cardiogenic diseases and hypertension as well as in elderly patients. The latter have also a poor post-operative outcome: 22 patients died. In contrast to hematoma thickness and midline shift, which do not have any influence on outcome, prognosis is mainly determined by age, complicating diseases, hypertension and diabetes mellitus. The chronic subdural hematoma is often found in multi-morbid patients.
