[Traumatic delayed intracerebral hematoma--clinical aspects]

Area of Science:

• Neurosurgery
• Traumatology
• Radiology

Background:

• Traumatic brain injury can lead to delayed intracerebral hematomas (secondary lesions).
• Comparing secondary lesions with immediate intracranial lesions provides insight into injury mechanisms and outcomes.

Purpose of the Study:

• To investigate the occurrence and management of traumatic delayed intracerebral hematomas.
• To compare the characteristics and prognosis of secondary lesions with immediate intracranial multiple lesions.

Main Methods:

• Retrospective analysis of 17 cases of delayed intracerebral hematoma (secondary lesions) from 401 head injury cases.
• Comparison with 11 cases of acute traumatic intracranial multiple lesions (immediate lesions).
• Evaluation of initial X-CT findings and patient outcomes.

Main Results:

• Secondary lesions exhibited a significantly worse prognosis (59% poor/fatal outcomes) compared to immediate lesions (27%).
• Hypertension was a risk factor, with 7 of 8 fatal cases being secondary lesions.
• Initial X-CT detected secondary lesions in only 59% of cases, with detection intervals varying widely.

Conclusions:

• Traumatic delayed intracerebral hematomas present a poorer prognosis than immediate traumatic intracranial lesions.
• Timely and accurate detection of secondary lesions is critical for effective management and improved patient outcomes.
• Further research into predicting and managing secondary lesions is warranted.
