Early surgery for posterior circulation aneurysms was attempted in the earliest experience of the senior author. Two of the first four patients died, one with a cardiac arrest following poorly controlled hypotension and hypothermia. Due to this early experience, and due to our referral pattern, most of the more than 1300 patients with surgery of their ruptured vertebral-basilar artery aneurysm (VBAA) were operated on 14 days or more following their last subarachnoid hemorrhage (SAH) and after the immediate effects of the hemorrhage and the consequences of the hemorrhage had passed.
