BACKGROUND AND PURPOSE: Hemicraniectomy is a decompressive surgery used to remove a large bone flap to allow edematous brain tissue to bulge extracranially. However, early indicators of the decompressive effects of hemicraniectomy are unclear. We investigated whether reduction of midline shift following hemicraniectomy is associated with improved consciousness and survival in patients with malignant middle cerebral artery infarctions. METHODS: We studied 70 patients with malignant middle cerebral artery infarctions (MMI) who underwent hemicraniectomies...

OBJECTIVE Therapeutic options for brain metastases (BMs) that recur after stereotactic radiosurgery (SRS) remain limited. METHODS The authors provide the collective experience of 4 institutions where treatment of BMs that recurred after SRS was performed with stereotactic laser ablation (SLA). RESULTS Twenty-six BMs (in 23 patients) that recurred after SRS were treated with SLA (2 patients each underwent 2 SLAs for separate lesions, and a third underwent 2 serial SLAs for discrete BMs). Histological findings in the BMs treated included the following: breast (n = 6); lung (n = 6); melanoma (n = 5); colon (n = 2); ovarian (n = 1); bladder (n = 1); esophageal (n = 1); and sarcoma (n = 1)...

BACKGROUND: Malignant middle cerebral artery infarct syndrome is a potentially fatal complication of stroke that is poorly understood in children. We studied the frequency, associated characteristics, and outcomes of this condition in children. METHODS: Children, aged two months to 18 years with acute middle cerebral artery infarct diagnosed at our center between January 2005 and December 2012 were studied. Associations with malignant middle cerebral artery infarct syndrome were sought, including age, seizures, neurological deficit severity (Pediatric National Institute of Health Stroke Severity Score), stroke etiology, fever, blood pressure, blood glucose, infarct location, infarct volume (modified pediatric Alberta Stroke Program Early Computed Tomography Score), and arterial occlusion...

OBJECTIVE: To verify if the size of the bone flap and the bone window area may have an impact on the outcome of decompressive craniectomy. PATIENTS AND METHODS: From February 2012 to February 2014, 42 patients with acute intracranial hypertension were enrolled in this study. We conducted standard craniotomy and decompressive hemicraniectomy on all patients. The intracranial pressure was measured before the hemicraniectomy operation, at the time of bone flap removal, at the time of the incision of the dura mater and 24 hours after the operation...

BACKGROUND: Decompressive craniectomy procedures are performed in patients with malignant intracranial hypertension. A bone flap is removed to relieve pressure. Later a second operation is performed to reconstruct the skull after brain swelling has resolved. This surgical treatment would be improved if it were possible to perform a single operation that decompressed the brain acutely while eliminating the need for a second operation. In order to design a device and procedure that achieves this objective it is essential to understand how the brain swells following a craniectomy procedure...

Following craniectomy, hygromas are relatively common. While many cases resolve spontaneously, some patients develop neurologic deficits. Management of symptomatic hygromas often involves shunting or drainage. We present two patients who three weeks after decompressive hemicraniectomy developed declining neurologic status secondary to enlarging hygroma. Failing conservative management, both were treated with urgent cranioplasty and returned to neurologic baseline. Early cranioplasty may be safe and effective for symptomatic collections...

BACKGROUND: While clinical trial data support decompressive hemicraniectomy (DHC) as improving survival among patients with severe ischemic stroke, quality of life outcomes among older persons remain controversial. AIMS: To aid decision-making and understand practice variation, we measured long-term outcomes and patterns of regional variation for a nationwide cohort of ischemic stroke patients after DHC. METHODS: Medicare fee-for-service ischemic stroke cases over age 65 during the year 2008 were used to create a cohort followed for 2 years (2009-2010) after stroke and DHC procedure...

BACKGROUND AND PURPOSE: The use of decompressive hemicraniectomy (DHC) for the treatment of malignant cerebral edema can decrease mortality rates. However, this benefit is not sufficient to justify its use in elderly patients. We investigated the effects of therapeutic hypothermia (TH) on safety, feasibility, and functional outcomes in elderly patients with malignant middle cerebral artery (MCA) infarcts. METHODS: Elderly patients 60 years of age and older with infarcts affecting more than two-thirds of the MCA territory were included...

BACKGROUND: Decompressive hemicraniectomy (DhC) is a life-saving surgical procedure being increasingly employed for malignant middle cerebral artery strokes. We examined the incidence of hemorrhagic transformation following DhC. METHODS: We retrospectively reviewed the charts and radiological images of patients who underwent DhC for malignant middle cerebral artery strokes. We classified the hemorrhagic events and assessed the short-term 30-day outcome associated with these events...

BACKGROUND: The risk of symptomatic infarct swelling has been reported to be higher in patients treated with recombinant tissue plasminogen activator (rt-PA). The aim of this study was to evaluate the timing of symptomatic infarct swelling after rt-PA treatment. METHODS: We retrospectively analyzed 14 868 patients with acute ischemic stroke from a stroke registry databank. We recruited patients with massive middle cerebral artery (MCA) infarction and symptomatic infarct swelling and excluded those with parenchymal or symptomatic hemorrhage...

BACKGROUND: Decompressive hemicraniectomy (DHC) for space-occupying cerebral infarction in older adults remains controversial, and there are limited nationwide data evaluating the outcomes after craniectomy for stroke by patient age. METHODS: Patients who underwent DHC for ischemic stroke were extracted from the Nationwide Inpatient Sample (2002-2011). Multivariable logistic regression examined in-hospital mortality and a poor outcome (death, tracheostomy and gastrostomy, or discharge to institutional care)...

BACKGROUND: Decompressive hemicraniectomy (DHC) is life-saving in patients with malignant middle cerebral artery infarction (MMI), but outcome, perspectives and complications after DHC in daily practice are largely unknown. METHODS: From 2008 until 2014, we extracted patient's characteristics as well as complications from our database for patients with MMI who underwent DHC. Additionally, we analysed medical records from the different rehabilitation steps. RESULTS: We identified 48 consecutive patients (mean 57 years, 21 male, 41...

BACKGROUND: Cerebral venous thrombosis (CVT) is a rare cerebrovascular event that can present with headache, seizure, and focal neurological deficits. Approximately 30%-40% of patients with CVT also present with intracranial hemorrhage. Current guidelines recommend anticoagulation after CVT even in the setting of intracranial hemorrhage, but the timing of initiation is unclear. We present a case of CVT where timing of anticoagulation was unclear by current guidelines. METHODS: We conducted a literature search with search terms of "cerebral venous thrombosis," "intracranial hemorrhage," and "anticoagulation...

BACKGROUND: Several small trials have inconclusively evaluated the effect of hemicraniectomy in reducing death and disability in acute ischemic stroke patients with large hemispheric infarctions. We compared the effects of hemicraniectomy on death and disability with conservative treatment in patients with large hemispheric infarctions. METHODS: We calculated pooled odds ratios (ORs) and 95% confidence intervals (CIs) using random-effects models from 7 randomized trials that compared hemicraniectomy with conservative treatment in acute ischemic stroke patients...

BACKGROUND: Whether infarct size modifies intra-arterial treatment effect is not certain, particularly in patients with large infarcts. We examined the effect of the baseline Alberta Stroke Program Early CT Score (ASPECTS) on the safety and efficacy of intra-arterial treatment in a subgroup analysis of the Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands (MR CLEAN). METHODS: MR CLEAN was a randomised, controlled, open-label, phase 3 trial of intra-arterial treatment in patients (aged ≥18 years from the Netherlands) with proximal arterial occlusion of the anterior circulation, given intra-arterial treatment within 6 h of stroke onset...

OBJECTIVE: Although age already is known as a crucial factor affecting the functional outcome after a hemicraniectomy for malignant hemispheric infarction, previous studies have used arbitrary age cut-offs of 50, 60, or 70 years. Therefore, this study investigated predictors of the functional outcome after a hemicraniectomy and attempted to determine the critical age for an unfavorable functional outcome. METHODS: A total of 38 patients with large hemispheric infarction were treated with a decompressive hemicraniectomy and the corresponding 1-year modified Rankin Scale (mRS) data obtained...
