Serial computerized tomographic evaluations in traumatic head injury

Area of Science:

• Neurosurgery
• Neurology
• Radiology

Background:

• Head-injured patients admitted to rehabilitation units may develop new lesions requiring intervention.
• Assessing neurological progress in these patients can be challenging.

Purpose of the Study:

• To evaluate the utility of serial computerized tomography (CT) scans in identifying post-acute neurological lesions in patients undergoing inpatient rehabilitation.
• To determine if routine CT scanning can aid in the early diagnosis of complications after severe traumatic brain injury.

Main Methods:

• A prospective study of 47 patients with traumatic head injuries admitted to an inpatient unit.
• Serial CT scans were performed at admission, one month, and three months post-admission, unless significant clinical improvement occurred.

Main Results:

• Nine out of 41 scanned patients (22%) required neurosurgical intervention for newly detected lesions (ventricular enlargement, subdural hematoma, cerebral abscess).
• Seven of these nine patients (78%) had pathological changes identified exclusively on post-admission CT scans.
• Only two patients had pre-admission scans showing changes.

Conclusions:

• Serial CT scanning is valuable for detecting significant neurological lesions in the post-acute phase of traumatic brain injury during rehabilitation.
• Implementing routine CT scans can facilitate earlier diagnosis and potentially minimize further brain injury in the rehabilitation setting.
