[Results of the operative treatment of the ruptured aneurysm: prospective clinical study]

Aneurysmal subarachnoid hemorrhage (SAH) is a dramatic, frequently fatal event. With the incidence of 10 to 15 in 100 000 and a total mortality which even today is 40-50%, it represents a significant problem. Early surgical care for the hemorrhaging aneurysms has, without doubt, an importance in prevention of the rupture, however different series show different results as regards surgical timing and they are very different as regards giving advantage to the early or delayed time of the operation. Our aim was to perceive the results of the treatment in our group of 197 consequently operated patients for ruptured aneurysms with a special attention to the time of operation. This was a prospective clinical study and it was carried out at the Institute for Neurosurgery in Belgrade. Mortality of the operative treatment was a total of 15.74% in the entire group. According to operative intervals from the early to the delayed mortality the range is 35.71%, 22.22%, 11.63% and 8.88% respectively. The results of the treatment are in direct connection with the seriousness of the clinical picture. Being in the group graded from 1-3 decreases the probability of a fatal outcome, and graded from 1-2 decreases probability of morbidity. Early operated patients who in our group included also the most serious cases, life endangered ones, although with higher mortality do not have higher morbidity.
