Cranial computerized tomography in carotid artery transient ischemic attacks

J Biller, D W Laster, G Howard

    European Neurology
    |January 1, 1982
    PubMed
    Summary

    Cranial computerized tomography (CCT) scans often appear normal in patients experiencing transient ischemic attacks (TIAs) in the carotid artery distribution. Cerebral atrophy was more common than expected, while acute lesions were rarely detected.

    Area of Science:

    • Neurology
    • Radiology
    • Neuroimaging

    Background:

    • Transient ischemic attacks (TIAs) in the carotid artery distribution are a critical warning sign for stroke.
    • Cranial computerized tomography (CCT) is a common diagnostic tool for evaluating acute neurological events.
    • Previous studies have reported varying frequencies of CCT findings in TIA patients.

    Purpose of the Study:

    • To evaluate the utility of CCT in detecting acute lesions in patients with carotid artery distribution TIAs.
    • To assess the incidence of cerebral atrophy and incidental findings in this patient cohort.
    • To compare CCT findings with previously reported data.

    Main Methods:

    • Retrospective analysis of 45 patients with carotid artery distribution TIAs.
    • Review of initial and follow-up cranial computerized tomography (CCT) scans.

  • Correlation of imaging findings with clinical presentation.

    • Main Results:

    • A high proportion (71.1%) of patients had normal CCT scans.
    • Cerebral atrophy was observed in 20% of patients, a higher incidence than previously reported.
    • Acute hypodense lesions, indicative of infarction, were identified in only 2.2% of patients.

    Conclusions:

    • Cranial computerized tomography (CCT) has limited sensitivity for detecting acute ischemic changes in the early stages of carotid artery TIAs.
    • Cerebral atrophy may be a more frequent finding in TIA patients than previously recognized.
    • Further investigation with advanced neuroimaging may be warranted for definitive diagnosis.
