Single fronto-temporal sylvian vein reconstruction when treating a large partially thrombosed aneurysm of the M1 middle cerebral artery

The article describes a clinical case of clipping the neck of large partially thrombosed aneurysm by using a transsylvian approach. A feature of the case is an atypical structure of the Sylvian fissure, with just one vein draining both the frontal and the temporal lobes and hindering access to the Sylvian fissure. The problem was solved by cutting the vein, performing the aneurysm neck clipping and suturing the cut vein by means of end-to-end technique.
