Objective
To determine whether brain connectivity differs between focal cortical dysplasia (FCD) types I and II.
Methods
We compared cortico‐cortical evoked potentials (CCEPs) as measures of effective brain connectivity in 25 FCD patients with drug‐resistant focal epilepsy who underwent intracranial evaluation with stereo‐electroencephalography (SEEG). We analyzed the amplitude and latency of CCEP...
Objective
To characterize seizure and cognitive outcomes of sparing vs removing an magnetic resonance imaging (MRI)–normal hippocampus in patients with temporal lobe epilepsy.
Methods
In this retrospective cohort study, we reviewed clinical, imaging, surgical, and histopathological data on 152 individuals with temporal lobe epilepsy and nonlesional hippocampi categorized into hippocampus‐spared...
Objective
To examine the true incidence of hemorrhage related to stereo‐electroencephalography (SEEG) procedures. To analyze risk factors associated with the presence of different types of hemorrhage in SEEG procedures.
Methods
This was a retrospective, single‐center observational study examining every SEEG implantation performed at our center from 2009 to 2017. This consisted of 549 consecutive...
Objective
We aimed to determine the rates and predictors of resection and seizure freedom after bilateral stereo‐electroencephalography (SEEG) implantation.
Methods
We reviewed 184 patients who underwent bilateral SEEG implantation (2009‐2015). Noninvasive and invasive evaluation findings were collected. Outcomes of interest included subsequent resection and seizure freedom. Statistical analyses...
Objective
Oroalimentary automatisms (OAAs) resembling normal alimentary behavior are stereotyped complex movements that may occur during epileptic seizures. They are considered common clinical signs in temporal lobe seizures, but their anatomofunctional mechanisms are not established. We took the opportunity of presurgical intracerebral recordings to study the relations between the occurrence of...
ObjectiveStereo‐electroencephalography (SEEG) is a procedure performed for patients with intractable epilepsy in order to anatomically define the epileptogenic zone (EZ) and the possible related functional cortical areas. By avoiding the need for large craniotomies and due to its intrinsic precision placement features, SEEG may be associated with fewer complications. Nevertheless, intracerebral electrodes...
The purpose of this study is to look at the prevalence, characteristics, and prognostic value of somatosensory auras (SSAs) in patients who have undergone temporal lobe epilepsy (TLE) surgery to treat drug‐resistant focal epilepsy. We retrospectively reviewed all patients with drug‐resistant epilepsy who underwent TLE surgery at Cleveland Clinic between 2005 and 2010 (n = 333) to study the prevalence,...
Purpose: Stereo‐electroencephalography (SEEG) enables precise recordings from deep cortical structures, multiple noncontiguous lobes, as well as bilateral explorations while avoiding large craniotomies. Despite a long reported successful record, its application in the United States has not been widely adopted. We report on our initial experience with the SEEG methodology in the extraoperative mapping...
