Risk Factors and Outcome of Seizures After Chronic Subdural Hematoma

Abstract

Lower mean GCS on admission is independently predictive of seizures, most of which occur within the first three months after CSDH.

Risk factors for reoperation after initial burr hole trephination in chronic subdural hematomas

“…In the literature, the proportion of patients with bilateral hematomas ranges between 10 to 30% [12,13,15,28]. In our cohort, 28% of patients had bilateral hematomas and these patients had an approximately 4-fold greater risk of surgical complications than patients with a single hematoma.…”

“…Numerous studies have assessed the risk factors for recurrence, with over 20 different factors identified, highlighting the complexity and heterogeneity of this condition [6,7,[12][13][14]20,22].…”

Seizures in Subdural Hematoma

“…The latter rate is similar to the one experienced by TBI without SDH. The risk of developing seizures in patients with chronic SDH ranges between 2.3 and 17 % depending on the type and severity of the head injury [12][13][14][15][16]. Clinical and radiological risk factors for developing seizures associated with chronic SDH include brain atrophy, mixed-density SDH, prior stroke, and low Glasgow Coma Scale (GCS) at presentation [16][17][18].…”

“…The risk of developing seizures in patients with chronic SDH ranges between 2.3 and 17 % depending on the type and severity of the head injury [12][13][14][15][16]. Clinical and radiological risk factors for developing seizures associated with chronic SDH include brain atrophy, mixed-density SDH, prior stroke, and low Glasgow Coma Scale (GCS) at presentation [16][17][18]. In patients with chronic SDH who underwent surgical intervention, the incidence of seizures is between 5 and 22 % in the acute postoperative period [17][18][19][20][21].…”

“…Considering the focal nature of the lesion, the commonly expected seizure types are various forms of partial-onset seizures with or without secondary generalization. However, the available literature regarding seizure types in patients with acute SDH indicates that about 60-80 % of the seizures following subdural hematoma are generalized, while only 20-40 % are focal seizures [16,18]. These reports raise questions regarding the certainty in seizure classification between primary generalized and secondary generalized convulsive seizures based purely on the available clinical seizure semiology.…”
