In 20% of cases with subarachnoid hemorrhage (SAH) the source remains unknown in the initial angiography. Suspicious angiographic findings of vascular malformations raise the question of the indication to perform explorative surgery. Based on experiences with seven cases, we would like to discuss the indication for surgery in cases of SAH without definite angiographic evidence of vascular malformation.
