Significance of consecutive bilateral surgeries for patients with acute subdural hematoma who develop contralateral acute epi- or subdural hematoma.

BACKGROUND

Although rare, patients with acute subdural hematoma (ASDH) because of severe head injury can develop contralateral acute epi- or subdural hematoma, requiring consecutive surgical procedures. The choice of treatment strategies for such patients is clinically important.

METHODS

Among 88 patients with ASDH who were surgically treated over 13 years, we encountered and studied 5 patients who developed contralateral acute epi- or subdural hematoma (5.7%).

RESULTS

All 5 patients were male, ranging in age from 17 to 40. According to the Glasgow Coma Scale on admission, 1 patient was rated 3, 1 was 4, 1 was 5, and 2 were 6. All patients underwent consecutive surgical procedures for ASDH and contralateral ASDH and/or acute epidural hematoma, and were given postoperative supportive therapy with barbiturates and mild hypothermia. Patients' outcomes according to the Glasgow Outcome Scale were as follows: 1 patient, good recovery (20.0%); 1, mild disability (20.0%); 2, severe disability (40.0%), and 1, persistent vegetative state (20.0%). No patients died. Although decompressive craniectomy and evacuation of hematoma may lead to contralateral acute epi- or subdural hematoma in patients with ASDH, this therapy is justified because hematoma irrigation with trephination therapy has a poor outcome for comatose patients.

CONCLUSION

Awareness of intraoperative brain swelling is important, as it suggests the development of contralateral hematoma. Immediate computed tomography and a rapid return to the operating room are therefore critical.
