RESUMO
Objective:To summarize the clinical characteristics and efficacy of hemorrhage resulted from cortical venous infarction with seizure as the first symptom after craniotomy.Methods:Eleven patients with hemorrhage resulted from cortical venous infarction with seizure as the first symptom after craniotomy admitted to Neurosurgical Center, 988 th Hospital of PLA Joint Logistic Support Force from June 2011 to September 2019 were chosen in our study; primary diseases included meningioma in 7 patients, contusion and laceration of frontal lobe in 2, hypertensive cerebral hemorrhage in 1, and obsessive-compulsive disorder in 1 patient. Epilepsy was the first symptom after craniotomy. Clinical characteristics and efficacy of these patients were analyzed retrospectively; seizure control efficacy was evaluated by Engel grading. Results:First seizure occurred 4 h-7 d after craniotomy in these 11 patients, including 2 with focal sensory retention seizure, 3 with focal bilateral tonic-clonic seizure, and 6 with general tonic-clonic seizure. Follow-up cranial CT revealed hematoma in surgical region, adjacent cortex or subcortex in 9 patients (hematoma volume: 15-50 mL); emergency craniotomy (hematoma clearance) and decompressive craniectomy was performed in 5 patients; only emergency craniotomy (hematoma clearance) was performed in 3 patients; conservative treatment was performed in 1 patient. A small amount of diffuse bleeding with severe cerebral edema in the surgical region appeared in 2 patients, and the transient limb paralysis gradually recovered after 2 months of conservative treatment. Follow-up was performed for (4.5±1.7) years ([2.3-7.0] years). During the last follow-up, 4 patients were normal, 5 patients had mild to moderate hemiplegia, 1 had mild decreased vision in the right eye, and 1 had long-term coma. Epileptic control efficacy analysis indicated that 8 had Engel grading I and 3 grading II.Conclusion:Complete removal of hematoma and inactivated brain tissues can effectively control seizures and rebleeding in patients with hemorrhage resulted from cortical venous infarction.
RESUMO
Objective:To investigate the imaging and electrophysiological characteristics, surgical methods and efficacies of preschoolers with refractory temporal lobe epilepsy.Methods:A retrospective data study was conducted on 27 patients with refractory temporal lobe epilepsy accepted surgical treatment in our hospital from June 2014 to January 2019. By combined with clinical manifestations, preoperative epileptogenic zones were evaluated by imaging data, such as MR imaging, MR spectroscopy and positron emission tomography-CT, and interictal and ictal video-electroencephalogram (VEEG) data. During the surgery, cortical electroencephalography (ECoG) and deep electrode monitoring were used to monitor and locate the abnormal discharge areas to guide the surgical excision of epileptic zone. Engel grading was used to evaluate the efficacy after surgery.Results:All children had typical clinical manifestations of temporal lobe epilepsy; abnormal signal images were found in one side of the temporal lobe and the hippocampus in MR imaging; epileptic discharges were originated from one side frontotemporal region in interictal and ictal VEEG. Obviously persistent or paroxysmal spike waves, spike waves and slow spikes and spike composite waves were intraoperatively discovered by ECoG and depth electrode electroencephalography in the temporal lobe. All patients accepted standard anterior temporal lobectomy+lesion resection+peripheral abnormal discharge resection of the temporal lobe cortex; partial insular lobe was excised and frontal cortex was performed low power thermal coagulation in two patients. Follow-up was performed for 6 months; Engel grading I was reported in 22 patients (81.5%), Engel grading II in 3 patients (11.1%), and Engel grading III in 2 patients (7.4%).Conclusion:Early surgery and moderate extension of resection under intraoperative ECoG and deep electrode monitoring are the key factors to improve the surgical efficacy of preschoolers with refractory temporal lobe epilepsy.
