    Computerized tomography (CT) revealed hemorrhagic infarction occurred twice as often in embolic strokes compared to thrombotic strokes. Anticoagulation did not worsen outcomes and resolved hemorrhagic aspects on follow-up scans.

    Area of Science:

    • Neurology
    • Radiology
    • Internal Medicine

    Background:

    • Distinguishing between embolic and thrombotic strokes is crucial for treatment decisions.
    • Computerized tomography (CT) plays a key role in stroke diagnosis and characterization.
    • Hemorrhagic infarction is a potential complication or presentation of ischemic stroke.

    Purpose of the Study:

    • To compare the frequency of hemorrhagic infarction on CT scans in patients with presumed embolic versus thrombotic strokes.
    • To evaluate the safety and effect of anticoagulation in stroke patients with hemorrhagic infarction.

    Main Methods:

    • Prospective study of 18 consecutive patients with embolic stroke criteria.
    • Sequential CT scans were performed.
    • CT findings were compared with those of patients with presumed thrombotic strokes.

    Main Results:

    • Hemorrhagic infarction appeared on CT scans in 22% of patients with presumed embolic strokes.
    • Hemorrhagic infarction appeared on CT scans in 10% of patients with presumed thrombotic strokes.
    • No patient experienced deterioration with anticoagulation, irrespective of CT findings.

    Conclusions:

    • Hemorrhagic infarction is twice as common in embolic strokes compared to thrombotic strokes on CT.
    • Anticoagulation is safe in patients with hemorrhagic infarction and can lead to resolution of the hemorrhagic aspect on follow-up CT scans.
