aIn three cases of low grade aSAH two aneurysms were treated within the initial ICU stay because the source of bleeding could not be determined with certainty in two cases an in one case a second aneurysm was located in close proximity to the ruptured one
bIn one case of low grade aSAH treatment was intentionally delayed because of presence of severe vasospasm on initial angiogram (the patient was admitted 8 days after the hemorrhage). The patient died due to fulminant pulmonary embolism 10 days later before the aneurysm had been secured
