Symptomatic intracranial steal

V Hachinski, J W Norris, P W Cooper

    Archives of Neurology
    |March 1, 1977

    Summary
    This summary is machine-generated.

    Intracranial lesions can cause blood flow redistribution, leading to symptoms. This study highlights three cases where symptoms stemmed from hemodynamic steal phenomena, not just the lesion itself.

    Area of Science:

    • Neurology
    • Neurosurgery
    • Radiology

    Background:

    • Shunting of blood around intracranial lesions is recognized.
    • Clinical symptoms are typically attributed to the lesion itself.

    Observation:

    • Three patients presented with symptoms related to altered regional cerebral blood flow (rCBF).
    • Angiography and rCBF studies were used for investigation.

    Findings:

    • Symptoms arose from hemodynamic steal within a cerebral hemisphere.
    • Symptoms arose from interhemispheric hemodynamic steal.
    • Symptoms arose from steal from the brain into a tumor.

    Implications:

    • This challenges the traditional view that symptoms are solely due to the lesion.
  • Recognizing hemodynamic steal is crucial for accurate diagnosis and management.
  • Understanding rCBF redistribution is vital in neurovascular and neuro-oncology cases.
