In recent years, various authors were able to show convincingly the influence of favorable time of operation on the treatment results in aneurysms (3, 4, 6, 9, 11, 121) This is essentially determined by recurrent hemorrhage and vasospasm. The first recurrent hemorrhage mostly occurs on the third to 11th day, with a peak on the seventh day (7). The period of predilection for vasospasm is between the fifth and 13th day after a subarachnoid hemorrhage (SAH) (4, 11, 12). The time factor thus plays an important role in the treatment of aneurysms. We analyzed our patient material with regard to the time factor.
