    Summary
    This summary is machine-generated.

    Multiple aneurysms on the same artery are rare, occurring in 2.8% of patients. This study details 10 cases, highlighting internal carotid artery involvement and rupture patterns in these uncommon cerebral aneurysm presentations.

    Area of Science:

    • Neurosurgery
    • Vascular Neurology
    • Radiology

    Background:

    • Cerebral aneurysms are a significant cause of cerebrovascular disease.
    • Multiple aneurysms are found in 17% of patients with cerebral aneurysms.
    • Aneurysms on the same artery are an uncommon subset of multiple aneurysms.

    Observation:

    • This study identified 10 patients with more than one aneurysm on the same cerebral artery.
    • The incidence of aneurysms on the same artery was 2.8% among treated cerebral aneurysms.
    • Internal carotid artery aneurysms were most frequent (7/10), followed by middle cerebral artery (2/10) and anterior communicating artery (1/10).

    Findings:

    • In cases with multiple aneurysms on the same artery, the larger proximal or distal aneurysm was the source of bleeding in six instances.

    Related Experiment Videos

  • Rupture from the smaller distal aneurysm occurred in one case.
  • The bleeding source was indeterminate in one case, and another associated aneurysm had bled in two cases.

    • Implications:

    • Understanding the specific rupture dynamics of same-artery aneurysms is crucial for accurate diagnosis and treatment planning.
    • These findings may influence surgical or endovascular strategies for managing complex multiple intracranial aneurysms.
    • Further research is warranted to elucidate the pathogenesis and optimal management of this rare aneurysm subtype.
