[Prognosis of ischemic complications following early surgical treatment of cerebral aneurysms].

A summarized severity index has been defined on the basis of 11 preoperative findings from clinical and neurological studies, cerebral angiography, computerized tomography of the brain, and electroencephalography in 71 patients operated on for early aneurysmal rupture. The value of the summary severity index has a closely linear negative correlation with the likelihood of favourable postoperative outcomes: with a high summarized index, a risk for postoperative ischemic events and deaths increases. The paper shows it advisable to predict postoperative ischemic complications while defining indications for early aneurysmal surgical treatment.
