Hemispherectomy complications in the light of craniocerebral disproportion: review of the literature and rationale for a filling-reduction cranioplasty.
Hemispherectomy has had excellent results in treating drug-resistant seizures of infantile hemiplegia, except for the vulnerability of the remaining hemisphere. The hemispherectomy cavity has been considered responsible for early and late complications. Modified techniques have been widely performed and are not without complications. CNS hemosiderosis is probably not the only explanation; the craniocerebral disproportion following the surgery, the shunt effect and low pressure of the cavity should also be taken into account. Splinting the remaining hemisphere to avoid its dislodgment could be important. One of our patients who suffered a series of complications hitherto unreported in the literature was eventually treated with a filling-reduction cranioplasty. The rationale for the technique can be inferred from the literature reviewed in the article. Our technique is validated by a follow-up of 28 years since the hemispherectomy and 13 years since treatment for complications.
