BACKGROUND: In contemporary microneurosurgery reducing retraction-induced injury to the brain is essential. Self-retaining retractor systems are commonly used to improve visualization and decrease the repetitive microtrauma, but sometimes self-retaining retractor systems can be cumbersome and the force applied can cause focal ischemia or contusions. This may increase the morbidity and mortality. Here, we describe a technique of retraction using 10-0 sutures in the arachnoid. OBJECTIVE: To evaluate the imaging and clinical results in patients where 10-0 suture retraction was used to aid the surgical procedure...

Post-traumatic pituitary apoplexy is uncommon, most of which present with a sudden onset of severe headache and visual impairments associated with a dumbbell-shaped pituitary tumor. We experienced an unusual case of post-traumatic pituitary apoplexy with atypical clinical features. A 66-year-old man presented with mild cerebral contusion and an incidentally diagnosed intrasellar tumor after a fall accident with no loss of consciousness. The patients denied any symptoms before the accident. After 4 days, the left oculomotor nerve palsy developed and deteriorated associated with no severe headache...

While most of pulmonary thromboembolism (PE) cases can be managed by thrombolytic and anticoagulation therapy, massive PE remains a life-threatening disease. Although surgical embolectomy can be a curative therapy for massive PE, peri-operative mortality for hemodynamically collapsed PE is extremely high. We present a case of hemodynamically collapsed massive PE. We avoided either thrombolytic therapy or surgical embolectomy, because the patient had recent cerebral contusion. Therefore, we managed the patient with the combination of veno-arterial extracorporeal membrane oxygenation (V-A ECMO) and conventional anticoagulation, which dramatically improved the patient's hemodynamics...

Delayed neurological deterioration following mild head injury(MHI)usually occurs within 24 hours. However, some cases require delayed surgical evacuation of an acute subdural hematoma(ASDH), owing to subacute progressive hematoma enlargement. This study aimed to determine radiological or clinical parameters associated with surgical intervention in ASDH cases in which surgery was not initially considered necessary. From 2010 to 2015, 64 patients were non-surgically treated for ASDH following MHI. We evaluated the various outcomes of eventual surgical ASDH evacuation after the first 48 hours following injury, due to hematoma enlargement and clinical deterioration...

Fall rates from 3.2 to 17.1 falls per 1,000 hospital days in geriatric psychiatry facilities have been reported to date. Up to 5% of the falls result in severe injuries, but data concerning medical consequences are scare. This brief report presents a retrospective analysis of one year fall protocols from a geriatric psychiatry department focusing on consequences of falls. Fall-induced injuries were rated in four categories: no injuries, mild injuries (contusions, hematomas, abrasions), moderate injuries (lacerations, dislocations), and severe injuries (fractures, cerebral hemorrhages)...

Neuronal death after traumatic brain injury (TBI) is a complex process resulting from a combination of factors, many of which are still unknown. Transient receptor potential melastatin 7 (TRPM7) is a transient receptor potential channel that has been demonstrated to mediate ischemic and traumatic neuronal injury in vitro. In the present study, TRPM7 was suppressed in the rat cerebral cortex by intracortical injections of viral vectors bearing shRNA specific for TRPM7 to investigate its potential role in an in vivo TBI model...

This historical review summarizes the most significant theories regarding the cause of death of King Henry II of France (1519-1559) and the circumstances under which it occurred. Although the historical testimonies are inconclusive and vague, postmortem analysis has shown that the King died of meningoencephalitis, caused by hematoma of a cerebral contusion, with effusion in the cerebral laminae and its surrounding tissue initiated by a periorbital fracture.

PURPOSE: The paranasal sinuses are complex anatomical structures of unknown significance. One hypothesis theorizes that the sinuses, in the event of a traumatic injury, function as a crumple zone to distribute and absorb energy to protect the brain and other critical structures. The current study investigates the association between frontal sinus (FS) volume and the severity of cerebral insults following craniofacial trauma. METHODS: All patients with FS fracture admitted to a level 1 trauma center from 2011 to 2014 were retrospectively reviewed...

This study tried to quantify spinal cord perfusion by using contrast-enhanced ultrasound (CEUS) in rhesus monkey models with acute spinal cord injury. Acute spinal cord perfusion after injury was detected by CEUS, coupling with conventional ultrasound (US) and Color Doppler US (CDFI). Time-intensity curves and perfusion parameters were obtained by autotracking contrast quantification (ACQ) software in the epicenter and adjacent regions of injury, respectively. Neurological and histological examinations were performed to confirm the severity of injury...

We compared the surgical efficacy of the supraorbital key-hole approach (SKA) to conventional unilateral frontotemporal craniotomy (UFTC) for the treatment of patients with unilateral-dominant bilateral frontal contusions (BFCs). A retrospective analysis of 62 patients with unilateral-dominant BFCs who underwent surgery at our institute between 2014 and 2017 was performed. There were 26 patients who underwent SKA (group A) and 36 who underwent UFTC (group B). Postoperative computed tomography scans showed satisfactory evacuation of the frontal cerebral contusions in both groups (p > 0...

INTRODUCTION: Advanced age has been traditionally associated with worse traumatic brain injury (TBI) outcomes. Although prompt neurosurgical intervention (NSI, craniotomy or craniectomy) may be life-saving in the older trauma patient, it does not guarantee survival and/or return to preinjury functional status. The aim of this study was to determine whether a simple score, based entirely on the initial cranial computed tomography (CCT) is predictive of the need for NSI and key outcome measures (e...

Factor VII (FVII) plays a key role in the initiation of the coagulation cascade and, in clinical situations, recombinant human activated FVII (rFVIIa) effectively prevents progressive hemorrhaging after a brain contusion. However, it remains unclear whether decreases in FVII activity directly lead to progressive hemorrhaging and, moreover, the precise mechanisms underlying this process are not yet known. The present study demonstrated that decreased FVII activity directly led to progressive hemorrhaging of the cerebral contusions...

Decompressive surgery to reduce pressure under the skull varies from a burrhole, bone flap to removal of a large skull segment. Decompressive craniectomy is the removal of a large enough segment of skull to reduce refractory intracranial pressure and to maintain cerebral compliance for the purpose of preventing neurologic deterioration. Decompressive hemicraniectomy and bifrontal craniectomy are the most commonly performed procedures. Bifrontal craniectomy is most often utilized with generalized cerebral edema in the absence of a focal mass lesion and when there are bilateral frontal contusions...
