Retro-odontoid cysts that arise from the tectorial membrane are uncommon lesions that can occur in elderly patients. They arise secondary to degenerative changes, including calcium pyrophosphate deposition within the ligaments. Surgical treatment is indicated when these lesions result in intractable pain, instability, and/or myelopathy. Several surgical techniques to treat this condition exist, but the optimal approach in elderly patients with comorbidities remains controversial. Here, the authors present a case series of 3 patients who underwent successful resection of a retro-odontoid lesion performed through a transdural approach...

To compare ICP derived cerebrovascular reactivity indices in their ability to predict 6-month outcome, and to determine/compare critical thresholds related to outcome for each index, in adult non-craniectomized traumatic brain injury (TBI). Using a retrospective cohort of non-decompressive craniectomy (non-DC) TBI patients, we performed univariate and multivariate binary logistic regression outcome analysis of: pressure reactivity index (PRx), pulse amplitude index (PAx) and a newly described index calculated as the Regression coefficient between intracranial pressure (ICP) waveform Amplitude and Cerebral perfusion pressure RAC (CPP)...

BACKGROUND: Two randomised controlled trials (RCTs) of decompressive craniectomy (DC) in traumatic brain injury (TBI) have shown poor outcome, but there are considerations of how these protocols relate to real practice. The aims of this study were to evaluate usage and outcome of DC and thiopental in a single centre. METHOD: The study included all TBI patients treated at the neurointensive care unit, Akademiska sjukhuset, Uppsala, Sweden, between 2008 and 2014. Of 609 patients aged 16 years or older, 35 treated with DC and 23 treated with thiopental only were studied in particular...

OBJECTIVE: Dural substitutes are used in decompressive craniectomy (DC) in order to prevent adhesions during subsequent cranioplasty. Current literature attributes them to the reduced blood loss and reduction in operative time of cranioplasty. The use of double layer substitute has rarely been documented. We decided to study the use of double layer G-patch as a dural substitute in DC and evaluate its outcome during subsequent cranioplasty with special focus on flap elevation time and blood loss during cranioplasty...

Stroke represents the most common fatal neurological disease especially in highly developed countries. Even today, treatment options are very limited. The development of new therapeutic approaches replies, to a great extent, on experimental rodent models of focal cerebral ischemia. Since ~80% of ischemic strokes occur in the area of middle cerebral artery (MCA), a number of these stroke models are based on this artery. The intraluminal monofilament model of MCA occlusion involves the insertion of a surgical filament inside the external carotid artery and its extension into the internal carotid artery until the tip occludes the source of the MCA-thus arresting blood flow with resultant infarction in the MCA area...

OBJECTIVE Direct brain compression and secondary injury due to increased intracranial pressure are believed to be the pathognomic causes of a grave outcome in acute subdural hemorrhage (aSDH). However, ischemic damage from aSDH has received limited attention. The authors hypothesized that cerebral microcirculation is altered after aSDH. Direct visualization of microcirculation was conducted in a novel rat model. METHODS A craniectomy was performed on each of the 18 experimental adult Wistar rats, followed by superfusion of autologous arterial blood onto the cortical surface...

To describe a new continuous index of physiologic measurement in a TBI population, the moving correlation coefficient between intracranial pressure (ICP) pulse amplitude (AMP) and cerebral perfusion pressure (CPP), which we refer to as RAC. We use patient examples of sustained intracranial hypertension, systemic arterial hypotension and plateau waves, as well as the retrospective analysis of 358 non-decompressive craniectomy (DC) traumatic brain injury (TBI) patients with high frequency ICP and ABP data, to explore the relationships of this new index, RAC, with AMP, ICP, CPP, RAP, pressure reactivity index (PRx) and pulse amplitude index (PAx)...

A 16-year-old boy with Chiari 1 malformation presented for an elective suboccipital craniectomy and C1 laminectomy. His intraoperative course was uneventful. At the conclusion of the procedure, he met extubation criteria and followed commands. After extubation, he developed progressive upper airway obstruction and became obtunded. He was reintubated via videolaryngoscopy, which showed edema not only to the tongue, but also to the posterior pharynx and blisters over the vocal folds and epiglottis. The patient was transferred to the pediatric intensive care unit intubated and sedated...

A 4-year-old male with headaches, papilledema, intracranial hypertension, and bilateral transverse sinus (TS) stenosis underwent attempted percutaneous placement of a right TS stent. Stent deployment was not technically feasible due to the stiffness of the stent and tortuosity of the patient's jugular bulb. Therefore, the patient underwent hybrid endovascular stenting of the right TS using neuronavigation and direct access of the TS following a single burr hole craniectomy. Two Express 8 mm × 17 mm balloon-mounted stents were deployed into the right TS, which resulted in obliteration of the preexisting trans-stenosis pressure gradient and decreased intracranial parenchymal pressure as monitored through an intracranial pressure bolt...

OBJECTIVE: In the severe traumatic brain injured (TBI) patient, maintaining the systolic blood pressure (BP) over 90 mmHg, the intracranial pressure (ICP) under 20 mmHg and the cerebral perfusion pressure (CPP) greater than 60∼70 mmHg is recommended to improve clinical outcomes. But a recommended CPP value for patients treated with decompression craniectomy (DC) is not clearly studied. The authors tried to determine whether the targeted CPP can be lowered in patients with DC. METHODS: 191 patients underwent DC for TBI included in this retrospective analysis...

It is not a common case for neurosurgery department and the other departments to perform joint operation at the same time. Patients with severe head injury are a condition in which vital signs are unstable due to severe brain swelling and increased intracranial pressure, and emergency surgery is required. A 44-year-old man visited the trauma center with a motorcycle accident. The Glasgow Coma Scale score at the time of emergency department was 3 points, and the pupil was fixed at 6 mm on both sides. His medical history was unknown...

Objective: After a rigorous management of increased intracranial pressure by decompressive craniectomy (DC), cranioplasty (CP) is usually carried out for functional and cosmetic purposes. However, the optimal timing of CP remains controversial. Our study aims to analyze the relationship between the optimal timing of CP and the post-operative complications. Methods: From January 2013 to December 2015, ninety patients who underwent CP in a single institution were analyzed...

Objective: Immediate contralateral epidural hematoma (EDH) and traumatic intracerebral hematoma (T-ICH) after craniectomy for traumatic subdural hematoma (SDH) are rare but devastating post-operative complications. Their clinical features and outcomes are not well studied. In this report, we present the clinical features and outcomes of immediate contralateral acute hematoma cases requiring a second operation. Methods: This study includes 10 cases of immediate contralateral EDH and T-ICH following bilateral craniectomy for the evacuation of traumatic SDH and contralateral hematoma between 2004 and 2015...

Scalp and calvarial masses are common in children and the differential diagnosis is broad. The authors recently cared for a child with an unusual fibro-osseous lesion of the temporal bone that has previously not been described in the pediatric neurosurgery literature. A 10-year-old girl presented with a firm, slowly enlarging protuberant mass arising from the squamous suture of the temporal bone without intracranial extension. The mass was removed en bloc through a temporal craniectomy and cranioplasty was performed...
