Abstract
The preservation of perforating arteries is important to gain a favorable outcome in surgery for cerebral aneurysms. At our hospital, factors relating to difficulties in preservation of these vessels are analyzed in a video. There are several technical solutions to related surgical problems.
1) proximal clipping or aneurysm trapping
2) dome clipping to decrease aneurysm volume
3) special dissection technique in case of tight adhesion between perforator and aneurysm
4) neck clipping technique without detachment of perforator adhesion
5) dome cutting for obtaining better perforator blood flow
These solutions can lead to a good outcome in cerebral aneurysm surgery by producing a better preservation rate of the perforator.
