Computed tomography in reversible ischaemic attacks: clinical and prognostic correlations in a prospective study

Area of Science:

• Neurology
• Radiology
• Cardiovascular Medicine

Background:

• Atherothrombotic ischemic attacks represent a significant cerebrovascular event.
• Computed tomography (CT) is a key diagnostic tool for evaluating acute neurological deficits.
• Understanding the relationship between ischemic attack severity and brain infarction is crucial for patient management.

Purpose of the Study:

• To prospectively evaluate patients with reversible atherothrombotic ischemic attacks using CT.
• To determine the frequency and correlates of brain infarction in this patient cohort.
• To investigate the relationship between neurological deficit duration and CT findings.

Main Methods:

• Prospective evaluation of 219 patients admitted with reversible atherothrombotic ischemic attacks.
• Computed tomography (CT) scans were performed to assess brain structure and identify infarctions.
• Correlation analysis was performed between CT findings, clinical presentation, and vascular imaging.

Main Results:

• Brain infarctions were observed in 64 patients (29.2%).
• Cerebral atrophy (44.4%) and ventricular dilatation (7.8%) were also noted.
• The frequency of brain infarction significantly correlated with the duration of neurological deficit (P = 0.005).

Conclusions:

• CT imaging is valuable in identifying brain infarctions in patients with reversible atherothrombotic ischemic attacks.
• The duration and severity of neurological deficits are associated with a higher likelihood of infarction.
• Further research may explore the prognostic implications of CT findings on recurrence rates.
