Recurrent Subdural Hematoma: An Institutional Experience

Area of Science:

• Neurosurgery
• Radiology
• Epidemiology

Background:

• Chronic subdural hematoma (CSDH) is a common neurosurgical condition.
• Burr hole irrigation and drainage often yield good results but recurrence is a concern.
• Reported recurrence rates for CSDH can be as high as 31.6%.

Purpose of the Study:

• To identify potential risk factors for CSDH recurrence.
• To provide insights for predicting patients at higher risk of recurrence.
• To aid in surgical decision-making for CSDH management.

Main Methods:

• Prospective and retrospective study design from 2017-2021.
• Analysis of patients who underwent surgery for CSDH, focusing on recurrence.
• Inclusion of ethical approval from the Institutional Ethics Committee.

Main Results:

• Male predominance observed (p=0.01).
• Heterogeneous subtypes (OR: 8.88, p=0.01) and larger midline shift (p=0.02) significantly predicted recurrence.
• Average age in recurrence group (71.5 years) was higher but not statistically significant.

Conclusions:

• Patient factors like male gender and radiological findings such as heterogeneous subtypes and significant midline shift indicate a higher recurrence risk.
• These factors can guide surgical planning and patient counseling.
• Further research may explore specific interventions for high-risk groups.
