In about 15 % of patients with SAH no causative vascular lesions can be found in acute imaging with CTA and DSA. Usually, repeat DSA is mandatory and bears the usual risk of invasive angiography. The present study attempts to assess the diagnostic impact of 3 D rotational angiography in order to avoid repeat DSA. ⋯ Using 3 D rotational DSA in initial imaging workup might help to reduce false-negative results concerning the bleeding source of acute SAH. At least because of this fact, 3 D rotational DSA should be part of the diagnostic workup after acute SAH.
