Mutual link among the approaches to clipping of basilar aneurysms

The pterional approach for basilar aneurysm clipping, has become the most common approach among surgeons, since it was advocated by Yasargil in 1982. However, other approaches aiming at an adequate but less invasive surgery to meet conditions of peripheral blood vessels (including aneurysmal size, direction and perforating arteries and arteriosclerosis) and the direction of clip insertion have also been developed. The approaches will be recommended to be expanded according to situations of the actual intra- operative findings in the future. The mutual link among the approaches to clipping of basilar aneurysms was investigated.
