Abstract

Objective

This current study was performed to evaluate whether superficial cerebral haemosiderosis (SCH) is still a complication of modern day anatomical hemispherectomy.

Methods

We report a 13-year institutional experience with anatomical hemispherectomy for intractable epilepsy. Seizure control at a mean follow-up interval of 7 years was 83%. Though one patient died post-operatively from a non-neurosurgical complication, mortality was otherwise zero and morbidity minimal. The much-described complication of SCH following anatomical hemispherectomy was non-existent. We explain the history of SCH as a complication of anatomical hemispherectomy, and the measures that are presently taken to prevent it.

Conclusions

We suggest that the importance of SCH in modern epilepsy surgery is probably over-emphasised.
