Abstract
This paper reports the removal of an intracerebral hematoma of the thalamus extending laterally or posterolaterally by a surgical route called the posterior trans-sylvian approach.
The posterior part of the sylvian fissure is opened under an operating microscope and the most posterior part of the island of Reil, which is the angiographical sylvian point, is approached along the transverse gyrus of Heschl. Then, the outer wall of the intracerebral hematoma can be punctured, and removed.
This approach was performed in four cases. A representative case is presented. The operative timing and the indication for the thalamic hemorrhage are discussed.
