    Small deep infarcts on computed tomography (CT) scans often indicate potential embolic sources, such as cardiac or carotid origins. Further investigation is crucial for selected patients with these findings.

    Area of Science:

    • Neurology
    • Radiology
    • Vascular Medicine

    Background:

    • Small deep infarcts are frequently observed on computed tomography (CT) scans.
    • These infarcts can present with clinical features consistent with lacunar syndromes.
    • Understanding the etiology of small deep infarcts is critical for patient management.

    Purpose of the Study:

    • To investigate the clinical and angiographic correlations of small deep infarcts detected via CT.
    • To determine the probable causes and sources of emboli associated with these infarcts.
    • To assess the necessity of further embolic source investigation in patients with small deep infarcts.

    Main Methods:

    • Retrospective analysis of 297 consecutive patients with small deep infarcts on CT scans.
    • Clinical data review for lacunar syndrome features.

  • Angiographic assessment to identify potential embolic sources (cardiac, carotid) and other vascular diseases.

    • Main Results:

    • A significant proportion of small deep infarcts were associated with probable embolic sources, primarily cardiac or carotid.
    • Some cases exhibited features consistent with Fisher's lacunar syndrome.
    • A smaller number of patients had other identified vascular diseases contributing to the infarcts.

    Conclusions:

    • The presence of small deep infarcts on CT necessitates a thorough evaluation for potential embolic sources.
    • Cardiac and carotid arteries are common origins for emboli leading to these infarcts.
    • Further investigation for embolic sources is recommended in selected patients presenting with small deep infarcts on CT.
