[Aneurysm surgery in relation to secondary intracranial findings]

In 116 patients operated on because of aneurysms we found 125 aneurysms, one convexity meningioma, and one A. V. supratentorial angioma. In 9 patients (8%) more than one aneurysm were found. In 8 patients there were double aneurysms and on one case 4 aneurysms, 18 of these 20 aneurysms were clipped. If these were situated on the same side they were treated simultaneously. If they were situated on two sides, the aneurysms were clipped in two surgical interventions. In 2 patients one of the two aneurysms remained untreated. Two interventions were also carried out for the combination aneurysm/tumor. After clipping the aneurysm, the meningioma was removed after an appropriate interval.
