Rebleeding during cerebral aneurysm angiography is common within 6 hours of rupture, leading to poor outcomes. Delaying angiography may improve prognosis if the hematoma is not large.

Area of Science:

  • Neurosurgery
  • Neuroradiology
  • Vascular Neurology

Background:

  • Cerebral aneurysms pose a significant risk of rupture and rebleeding.
  • Angiography is crucial for diagnosis but carries a risk of precipitating rebleeding.

Purpose of the Study:

  • To analyze clinical data on rebleeding during cerebral aneurysm angiography.
  • To evaluate the impact of the time interval between aneurysm rupture and angiography on rebleeding risk and patient outcomes.

Main Methods:

  • Review of 14 personal cases and 202 patients from existing literature.
  • Analysis of rebleeding events in relation to timing of angiography post-rupture.

Main Results:

  • Rebleeding during angiography occurred in 78% of cases on Day 0.

Related Experiment Videos

  • 89% of rebleeding events happened when angiography was performed within 6 hours of the latest rupture.
  • Mortality associated with rebleeding during angiography was high at 79%.

    • Conclusions:

    • Performing angiography within 6 hours of cerebral aneurysm rupture significantly increases the risk of rebleeding.
    • An intentional delay of at least 6 hours for angiography is recommended for patients without large hematomas to potentially improve prognosis.
