OBJECTIVE: The treatment of severe spinal deformities in pediatric patients is very challenging. Posterior only vertebral column resection (PVCR) allows for correcting of severe deformities of the vertebral column via a posterior only procedure. We analyzed radiological outcome of PVCR performed on a series of pediatric patients with severe congenital and acquired spinal deformities. METHODS: A case series of eleven pediatric patients with severe spinal deformity who were treated by PVCR between 2009 and 2013 were retrospectively analyzed...

Neurocritical care has two main objectives. Initially, the emphasis is on treatment of patients with acute damage to the central nervous system whether through infection, trauma, or hemorrhagic or ischemic stroke. Thereafter, attention shifts to the identification of secondary processes that may lead to further brain injury, including fever, seizures, and ischemia, among others. Multimodal monitoring is the concept of using various tools and data integration to understand brain physiology and guide therapeutic interventions to prevent secondary brain injury...

STUDY DESIGN: Retrospective Study. OBJECTIVES: This study is to measure and analyze the changes of three-dimensional distances of spinal column and spinal canal at the three-column osteotomy sites and address their clinical and neurologic significance. SUMMARY OF BACKGROUND DATA: Three-column osteotomies were developed to treat severe and stiff spine deformities with insufficient understanding on the safe limit of spine shortening and the relationship between the shortening distance of the spinal column and that of the spinal canal...

We depict the transoral endoscopic thyroidectomy vestibular approach (TOETVA). Patient selection criteria are (1) ultrasonographically (US) estimated thyroid diameter no larger than 10cm, (2) US estimated gland volume ≥45mL, (3) nodule size ≥5mm, (4) a benign tumor, such as a thyroid cyst, single-nodular goiter, or multinodular goiter, (5) follicular neoplasm, and (6) papillary microcarcinoma without evidence of metastasis. TOETVA is carried out through a three-port technique placed at the oral vestibule, one 10mm port for 30° endoscope and two additional 5mm ports for dissecting and coagulating instruments...

BACKGROUND: C5 palsy is a serious complication after cervical decompression surgery in which the patient shows a deterioration in power of the deltoid or biceps brachii by at least one grade in the manual muscle test without aggravation of lower extremity function. Although there are several hypotheses regarding the etiology of C5 palsy, the pathogenesis and preventive measures remain unidentified and many other controversies remain. OBJECTIVE: To systematically review the clinical features, risk factors, mechanism, and preventive measures of C5 palsy after posterior cervical decompression surgery...

BACKGROUND: Neuromonitoring devices to assess level of sedation are now used commonly in many hospital settings. We previously reported that electro-encephalic-graphic (EEG) spikes frequently occurred after the time of death in patients being neuro-monitored at the time of cessation of circulation. In addition to our initial report, end of life electrical surges (ELES) have been subsequently documented in animal and human studies by other investigators. The frequency, character, intensity, and significance of ELES are unknown...

PURPOSES: During esophageal surgery, clamping injury and injury associated with the use of energy devices are common mechanisms underlying intraoperative recurrent laryngeal nerve (RLN) damage. Recently, intraoperative neuromonitoring (IONM) has been applied to prevent RLN injury. This study was aimed at investigating the changes in the EMG signals associated with clamping injury of the RLN caused by picking up of the nerve with tweezers in domestic pigs. METHODS: Six domestic pigs (12 RLNs) underwent continuous IONM (CIONM) by our original automated periodic vagal nerve stimulation method...

INTRODUCTION: Intraoperative neuromonitoring (IONM) has been a commonly used technology during thyroid surgery aimed at reducing the incidence of recurrent laryngeal nerve palsy (RLNP), which is a severe complication and leads to significant impacts on a patient's life. In order to give a comprehensive assessment for potential benefits and disadvantage of IONM, this meta-analysis and systematic review discusses RLNP rate, predictive power, continuous intraoperative neuromonitoring (CIONM), and emphasises application during thyroid cancer surgeries...

Correction forces during spine deformity surgery including distraction, impart significant stresses to the spinal cord, which may result in permanent injury. Intraoperative neuromonitoring (IONM) is commonly used by surgeons to recognize possible damage to the spinal cord in cases of evident traumatic or vascular damage to the spinal cord. However, mild insult to the spinal cord, which does not result in obvious trauma or electrophysiological changes, present a major clinical challenge as the mechanisms of this type of spinal cord injury (SCI) remain largely unknown, and thus preventive strategies are lacking...

BACKGROUND: Percutaneous techniques have increasingly gained popularity in recent years. The application of technological innovation, including neuromonitoring techniques, has the potential to increase the safety and efficacy of these procedures. METHODS: Thirty patients suffering from osteoporotic dorsolumbar burst fracture were prospectively enrolled in this study. The patients underwent percutaneous fenestrated pedicle screw fixation augmented with polymethylmethacrylate (PMMA) injection...

PURPOSE: The vagus nerve (VN) has essential regulatory roles in the gastric acid secretion and gastrin release. Continuous intraoperative neuromonitoring (CIONM) via VN stimulation is a promising technique in thyroid surgery because it potentially avoids injury to the recurrent laryngeal nerve. However, no studies have investigated changes in gastric acid secretion and gastrin release during CIONM. METHOD: This prospective study of 58 thyroid surgery patients compared gastric acid and serum gastrin at five time points: (1) before skin incision, (2) after baseline calibration of CIONM probe, (3) +20 min from baseline, (4) before probe removal, and (5) after extubation...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) requires large-bore vascular access due to the considerable diameters of the endoprosthesis and delivery device. The preclose technique preceding endograft delivery has opened the door for an evolved access strategy. In addition, treatment under local anesthesia offers the advantage of optimal neuromonitoring. The goal of this study was to analyze the efficacy and safety of percutaneous TEVAR under local anesthesia. METHODS: All patients undergoing TEVAR in an elective setting at the Antwerp University Hospital between June 2012 and June 2015 were prospectively entered into an endovascular database...

BACKGROUND: Patients who undergo clipping of cerebral aneurysms face inherent risk for new postoperative neurological deficits. Intraoperative neuromonitoring (IONM) is used often for early detection of ischemic changes, while still potentially reversible. However, the value, safety, and efficacy of temporary clipping and multimodal intraoperative neuromonitoring (IONM) to minimize risks are debated. Our retrospective series examined the sensitivity and specificity of IONM using transcranial motor evoked potentials (MEPs) and somatosensory evoked potentials (SSEPs), and quantified the safety of temporary clipping by duration and vascular territory...

INTRODUCTION: Intraoperative neurophysiological monitoring (IONM) has proven to help reduce the probability of postoperative neurological deficit for spinal deformity correctional surgeries. However, in rare cases new deficits may still happen. We report a surgical case in which the patient had postoperative paralysis. We would like to call for more case reports with postoperative neurological deficits as they present difficult clinical cases. PRESENTATION OF CASE: A 61-year-old male patient with severe thoracolumbar kyphoscoliosis underwent posterior spinal correction and fusion with segmental T10-L5 pedicle screws and rods instrumentation with IONM...
