Practitioner-Guided Note
When evaluating incidental aneurysms, prioritize screening for patients with polycystic kidney disease or multiple affected first-degree relatives. Be vigilant with new diplopia, which demands immediate screening regardless of age. Remember that non-contrast CT sensitivity for subarachnoid hemorrhage is highest within the first 24 hours, and that posterior circulation locations significantly increase the risk of rupture or thromboembolism.
Key Takeaways
Aneurysms over seven millimeters or in the posterior circulation carry higher rupture risks.
Polycystic kidney disease and family history are major risk factors for a rupture.
Non-contrast CT catches ninety-eight percent of subarachnoid hemorrhages within twenty-four hours.
Fusiform aneurysms lack a distinct neck and are more common in older male smokers.
