Supports repeat angiography in spontaneous SAH after negative initial study; leaves open prospective validation before routine adoption.
Does repeat-angiography improve the detection of aneurysms in patients with spontaneous SAH and negative initial angiography?
Repeat-angiography detects a missed aneurysm in nearly 20% of patients with spontaneous SAH and initially negative angiography, highlighting its importance in this clinical scenario.
