Electroconvulsive therapy for super refractory status epilepticus in pregnancy: case report and review of literature.

OBJECTIVE: We aim to describe use of electroconvulsive therapy (ECT) to treat super refractory status epilepticus (SRSE) in pregnancy and review the literature regarding utility and safety of ECT in refractory status epilepticus. BACKGROUND: Status epilepticus (SE) is a commonly encountered emergency in neuro-critical care world. Pharmacotherapy of status epilepticus in pregnancy is very challenging given the effect of the majority of antiepileptic drugs (AEDs) on fetal development. Although there has been growing evidence for use of ECT in status epilepticus, data about its utility in pregnancy is lacking. DESIGN/METHOD: A twenty-one year old Caucasian female with history of epilepsy presented at 8 weeks of gestation as status epilepticus (SE) after abrupt discontinuation of her AEDs. Treatment was initiated with standard regimen of benzodiazepine and levetiracetam, which was progressively expanded to include approximately 10 anti-epileptic drugs over the course of 30 days. The status epilepticus was super refractory to sedation. She underwent ECT on day 31 with remarkable improvement in electroencephalogram (EEG) pattern and resolution of status epilepticus following a single ECT session. We reviewed PubMed and collated case reports involving the use of ECT in status epilepticus with emphasis on differences in various confounding factors esp. etiology of status and age group. CONCLUSION: Our case is the first reported case of ECT for successful treatment of SRSE in pregnancy. While majority AEDs pose a significant maternal and fetal risk during pregnancy, ECT could be a potential frontline therapy for SE in pregnancy.

Tethered brain: disentangling unintentional brain-mesh interfaces. Illustrative case.

BACKGROUND: Surgical meshes have found widespread use in neurosurgical practice. While commonly recognized risks of synthetic mesh include infection, exposure of mesh implants, and foreign body reaction, the risk of mesh tethering to neural structures is often overlooked. OBSERVATIONS: The authors presented the first case, to their knowledge, of the disentanglement of mesh interfaced to cortical tissue. The patient, a 68-year-old woman, presented with severe intractable seizure disorder and worsening left hand function and incoordination after meningioma resection and cranioplasty 9 years earlier. Magnetic resonance imaging (MRI) demonstrated interval progression of macrocystic encephalomalacia involving the right supplementary motor area, with fluid-attenuated inversion recovery signal extending posteriorly into the right primary motor cortex. Both computed tomography and MRI suggested potential tethering of the cortex to the overlying cranioplasty mesh. Because of the progressive nature of her condition, the decision was made to surgically remove the tethered mesh. LESSONS: De-tethering brain parenchyma from surgical mesh requires careful microdissection and judicious use of electrocautery to minimize further tissue damage and preserve neurological function. This inadvertent complication evinces the importance of using dural substitutes when unable to primarily repair the dura to prevent scarring and tethering of neural tissues to synthetic cranioplasty materials.
