Resective epilepsy surgery should be considered for children with LGS, despite abundant generalized and multiregional electroencephalogram abnormalities.
ObjectiveCraniotomy (CO) and decompressive craniectomy (DC) are two main surgical options for acute subdural hematomas (ASDH). However, optimal selection of surgical modality is unclear and decision may vary with surgeon's experience. To clarify this point, we analyzed preoperative findings and surgical outcome of patients with ASDH treated with CO or DC.MethodsFrom January 2010 to December 2014, data for 46 patients with ASDH who underwent CO or DC were retrospectively reviewed. The demographic, clinical, imaging and clinical outcomes were analyzed and statistically compared.ResultsTwenty (43%) patients underwent CO and 26 (57%) patients received DC. In DC group, preoperative Glascow Coma Scale was lower (p=0.034), and more patient had non-reactive pupil (p=0.004). Computed tomography findings of DC group showed more frequent subarachnoid hemorrhage (p=0.003). Six month modified Rankin Scale showed favorable outcome in 60% of CO group and 23% of DC group (p=0.004). DC was done in patient with more unfavorable preoperative features (p=0.017). Patients with few unfavorable preoperative features (<6) had good outcome with CO (p<0.001).ConclusionIn selective cases of few unfavorable clinical findings, CO may also be an effective surgical option for ASDH. Although DC remains to be standard of surgical modality for patients with poor clinical status, CO can be an alternative considering the possible complications of DC.
Objectives The unfavorable surgical results that have been reported with insular epilepsy surgery may be related to inadequate monitoring. Insular epilepsy surgery requires the precise monitoring and tailored removal of the epileptic zone. The purposes of this study were to precisely monitor the hidden cortex and determine the effectiveness of using different monitoring methods, including subpial depth electrodes. Materials and methods This is a study of a single center series of six patients (three men, three women) who underwent insular surgery between May 2006 and December 2007. All patients had experienced medically intractable seizures without any evidence of a tumorous condition based on previous examination. We used strip electrode implantation in one patient and stereotactic depth electrode insertion in two patients, which resulted in partial removal of the insular. The other three patients underwent open direct subpial depth electrode insertion, which resulted in total removal of the insular cortex. Results There were no surgery-related complications with the insulectomy after insertion of the subpial depth electrodes, regardless of the monitoring method or extent of removal. All patients except for one showed considerable improvement in epilepsy (83.3% Engle class I, 16.5% Engle class II). In the three patients who had open direct subpial depth electrodes inserted, we achieved total insulectomy without increasing the surgical morbidity, while in the other three patients, the insular removal was only partial. Conclusion We demonstrate that image-guided insular surgery with safe and accurate depth electrode guidance results in an optimal outcome and complete resection of the insular cortex.
