| Total number of AE | 164 | |
A total of 164 AE occurred in 117 patients, whereby in some cases more than one AE occurred. In the third column, the resulting grade of AE (Clavien–Dindo–Grade (CDG)) is displayed. The most frequent CDG per diagnoses are marked in bold. *Patient suffering from an entrapped temporal horn due to tumor occlusion with implantation of a ventriculoperitoneal shunt during biopsy which needed revision surgery due to an non-functional gravitational device.
The underlying diagnosis that lead to AE are shown.
