✓ An autopsy study was made of the size of 191 saccular intracranial aneurysms (54 ruptured, 137 unruptured). Variations with age and sex, and ruptured and unruptured state were recorded and analyzed. Measurements on unfixed, unruptured aneurysms inflated by perfusion under 70 mm Hg pressure indicated that the size of aneurysms as generally determined in autopsy material is deceptively low.
