Intractable seizures after cranioplasty, a dreadful post-operative complication managed efficiently from Nepal: A case series.

Introduction And Importance: Cranioplasty is an elective neurosurgical procedure following decompressive craniectomy, often associated with post-operative complications such as hemorrhage, seizures, infection, hydrocephalus, and bone resorption. While seizures post-cranioplasty is not uncommon, Intractable seizures are rare but a dreadful complication following cranioplasty.

Case Summary: A 23 and 17-year-old male underwent decompression craniectomy for traumatic brain injury and subsequently underwent titanium mesh and acrylic cranioplasty respectively, During the post-operative period both patients developed intractable seizures. Initially seizures were refractory to multiple anti-epileptic drugs and benzodiazepine induced coma. Intractable seizures were controlled gradually with few anti-epileptic drugs after the removal of cranioplasty. During 2 years' follow-up, there was no new episode of seizures complained by patients.

Discussion: Elective cranioplasty following decompressive craniectomy after traumatic head injury is one of the commonest surgical modality carried out globally as a life saving measure. But post-operative complications following cranioplasty such as wound infection, implant displacement, bone resorption, hydrocephalus, epidural hematoma are the commonest observed complications whereas post-operative seizure is the most dreadful complication needing immediate intervention. Along with it intractable seizure is rarer during post- operative period.

Conclusion: Intractable seizures post-cranioplasty, though rare, are serious and often linked to cerebral edema from negative pressure drainage and dysregulation of cerebral blood flow. Removing the cranioplasty can restore blood flow regulation, stabilize brain tissue, and resolve seizures. Care providers should be aware of this rare complication and to be counselled the patient and the family before the surgery.
