A study using an ovine model of transdermal intrathecal catheterization was planned to investigate the neurotoxicity ofmagnesium sulfate. Nonpregnant Merino cross ewes (n = 8; age, 5 y; weight, 55.0 ± 6.5 kg) were anesthetized for placementof a lumbar intrathecal catheter. The study protocol defined a 5-d recovery period after introduction of the catheter before theadministration of test substances (2 mL of 0.9% saline or 50 or 150 mg MgSO4) followed by euthanasia 1 wk later. Although 3sheep successfully completed the study as planned, one of the remaining 5 sheep was withdrawn when the catheter was accidentally dislodged 2 d after anesthesia; another was withdrawn because of persistent neurologic deficits of the left hindlimb and intense pruritus during the first 24 h after placement of the catheter; and the remaining 3 animals experienced unacceptable complications within the first 4 h of administration of the test substance...

BACKGROUND AND PURPOSE: Delayed cerebral ischemia is a severe complication of aneurysmal SAH and is associated with a high case morbidity and fatality. The total blood volume and the presence of intraventricular blood on CT after aneurysmal SAH are associated with delayed cerebral ischemia. Whether quantified location-specific (cisternal, intraventricular, parenchymal, and subdural) blood volumes are associated with delayed cerebral ischemia has been infrequently researched. This study aimed to associate quantified location-specific blood volumes with delayed cerebral ischemia...

Background: Intracranial hemorrhage (ICH) is a serious, life-threatening, but fortunately rare complication of non-vitamin K oral anticoagulant (NOAC) therapy. There are limited data on NOAC-related ICH prognosis. Methods: All consecutive patients admitted to a single center due to acute NOAC-related ICH from September 2012 until the beginning of 2017 were included. Risk factors, type of NOAC, and location of ICH were evaluated. Risk for ischemic and bleeding events and clinical status upon admission and at discharge were evaluated using standard scales...

Flow diverting devices (FDDs) have revolutionized the treatment of morphologically complex intracranial aneurysms such as wide-necked, giant, or fusiform aneurysms. Although FDDs are extremely effective, they carry a small yet significant risk of intraprocedural complications. As the implementation of these devices increases, the ability to predict and rapidly treat complications, especially those that are iatrogenic or intraprocedural in nature, is becoming increasingly more necessary.Our objective in this paper is to provide a descriptive summary of the various types of intraprocedural complications that may occur during FDDs deployment and how they may best be treated...

Non-traumatic intracranial hemorrhage (ICH) is a devastating event associated with a high rate of morbidity and mortality. Patient age, hemorrhage location, number of foci, and underlying diseases are important clues to the etiology. Non-contrast head CT, given its availability and high sensitivity in detecting blood products, is frequently the first tool to readily detect ICH; however, different types of hemorrhages may share a common appearance on CT and the optimal therapeutic approach varies depending on etiology...

Left ventricular assist devices (LVADs) have become an important advancement for patients with end-stage heart failure. Left ventricular assist devices come with the risk of stroke and pump thrombosis, and to mitigate these risks, anticoagulation is given to these patients. With anticoagulation comes increased bleeding risk, and urgent reversal may be necessary. Reports have shown that the risk of thrombosis with prothrombin complex concentrate (PCC) does exist, especially in patients with baseline risk factors for thrombosis...

Spinal cord injury (SCI) represents an extremely debilitating condition for which no efficacious treatment is available. One of the main contributors to the inhospitable environment found in SCI is the vascular disruption that happens at the moment of injury that compromises the blood-spinal cord barrier (BSCB) and triggers a cascade of events that includes infiltration of inflammatory cells, ischemia and intraparenchymal hemorrhage. Due to the unsatisfactory nature of revascularization following SCI, restoring vascular perfusion and the BSCB seems an interesting way of modulating the lesion environment into a regenerative phenotype, with a potential increase in functional recovery...

Posterior reversible encephalopathy syndrome (PRES) is clinically characterized by seizures, changes in vision, altered mental status, and headache, with associated radiologic changes on brain imaging. Intraparenchymal hemorrhage is a rare complication of PRES and an atypical initial presentation of this condition. In this report, we discuss two patients who presented with multifocal cerebral hemorrhages that were later attributed to PRES. We further expand on the pathophysiology, management, and prognosis on patients with hemorrhagic PRES...

Intracranial aneurysms in the neonate, presenting in the first 4 weeks of life, are exceedingly rare. They appear to have characteristics, including presentation and location, that vary from those found in adults. The authors present a case of a 28-day-old neonate with a ruptured distal middle cerebral artery (MCA) aneurysm. Initial noninvasive imaging with transfontanelle ultrasound and CT confirmed intraparenchymal and subarachnoid hemorrhage. Contrast-enhanced MRI revealed a 14-mm ruptured fusiform MCA aneurysm that was not identified on time-of-flight magnetic resonance angiography (MRA)...

BACKGROUND AND PURPOSE: The impact of blood-brain barrier (BBB) disruption can be detected by intraparenchymal hyperdense lesion on the computed tomography (CT) scan after endovascular stroke therapy. The purpose of this study was to determine whether early BBB disruption predicts intracranial hemorrhage and poor outcome in patients with acute ischemic stroke treated with mechanical thrombectomy. METHODS: We analyzed patients with anterior circulation stroke treated with mechanical thrombectomy and identified BBB disruption on the noncontrast CT images immediately after endovascular treatment...

Stroke in pregnant women has a mortality rate of 1.4 deaths per 100,000 deliveries. Vascular malformations are the most common cause of hemorrhagic stroke in this population; preeclampsia and other risk factors have been identified. However, nearly a quarter of strokes have an undeterminable cause. Spontaneous intracranial hemorrhage (ICH) is less frequent but results in significant morbidity. The main objective of this study is to review the literature on pregnant patients who had a spontaneous ICH. A systematic review of the literature was conducted on PubMed and the Cochrane library from January 1992 to September 2016 following the PRISMA guidelines...

Traumatic brain injury (TBI) diagnoses have increased in frequency during the past decade, becoming a silent epidemic. The pathophysiology of TBI involves pathophysiological processes affecting the brain, induced by traumatic biomechanical forces resulting in temporary impairment of neurological function. Preclinical models have been generated to recapitulate the mechanical, neuroinflammatory, and behavioral outcomes observed in the clinical setting. The lateral fluid percussion (LFP) model is the most extensively used and well-characterized model of nonpenetrating and nonischemic TBI...

BACKGROUND: End-stage liver disease (ESLD) is a devastating consequence of hepatocyte destruction that is associated with intracranial hemorrhage (ICH). OBJECTIVE: To determine if ESLD in patients with ICH is associated with increased mortality. METHODS: We performed a single-center, retrospective cohort study of 53 patients (33 ESLD and 20 non-ESLD patients) who received neurosurgical care between 2006 and 2017. The exposure of interest was ESLD defined clinically as severely impaired liver function and at least one major complication of liver failure...

RATIONALE: To date, the only treatment approved for acute ischemic strokes is thrombolysis. Whether intravenous thrombolysis may be safe in patients taking direct oral anticoagulants (DOACs) is currently a matter of debate. PATIENT CONCERNS: A 74-year-old woman, who was on rivaroxaban 20 mg/d for nonvalvular atrial fibrillation, was admitted to our stroke unit with left-sided hemiparesis and aphasia. The onset of neurologic deficits had occurred 5 hours after the last rivaroxaban dose...

PURPOSE: To study whether clinical outcome data from our patient cohort could give support to the new recommendation in the AHA/ASA guidelines for the management of aneurysmal subarachnoid hemorrhage that states "that microsurgical clipping may receive increased consideration in patients with ruptured middle cerebral artery (MCA) aneurysms and large (>50 mL) intraparenchymal hematomas", while clinical outcome data supporting this recommendation are sparse. METHODS: We reviewed the clinical and radiological data of 81 consecutive patients with MCA aneurysms and concomitant hematomas admitted between January 2006 and December 2015...

Current clinical guidelines recommend elevating the mean arterial blood pressure (MAP) to increase spinal cord perfusion in patients with acute spinal cord injury (SCI). This is typically achieved with vasopressors such as norepinephrine (NE) and phenylephrine (PE). These drugs differ in their pharmacological properties and potentially have different effects on spinal cord blood flow (SCBF), oxygenation (PO2 ), and downstream metabolism after injury. Using a porcine model of thoracic SCI, we evaluated how these vasopressors influenced intraparenchymal SCBF, PO2 , hydrostatic pressure, and metabolism within the spinal cord adjacent to the injury site...
