The mechanismus of recurrence and enlargement of 16 cerebral aneurysms have been analyzed: 2 dissecting aneurysms, 6 fully grown aneurysms a fter neck clipping, 1 case after treatment with dome clip, 3 ruptured aneurysms that developed at the same sites and 4 cases that developed at other sites. From our investigation we concluded it was fundamental ly important that the factor of the elastic lamina interna must attach in whole around the neck with precise neck clipping or adequate tight embolization involving positioning of the remaining elastica lamina i nterna in coil embolization.
