Intracranial extradural collection may cause an increase in intracranial pressure, requiring rapid emergency treatment to reduce morbidity and mortality. We described an alternative CT-guided percutaneous access for extradural collection drainage. We report a case of a patient with previous craniectomy for meningioma ressection who presented to the Emergency Department with symptoms of intracranial hypertension. Brains CT showed a extradural collection with subfalcine herniation. After multidisciplinary discussion a CT-guided percutaneous drainage through previous burr hole was performed...

BACKGROUND AND PURPOSE: Patients with idiopathic intracranial hypertension have transverse sinus stenosis on gadolinium-bolused MRV, but other MR imaging signs are less consistently seen. Our aim was to demonstrate that transverse sinus stenosis could be identified on conventional MR imaging, and this identification would allow improved diagnostic sensitivity to this condition. MATERIALS AND METHODS: MR imaging and MRV images from 63 patients with idiopathic intracranial hypertension and 96 controls were reviewed by using 3 independent procedures...

PURPOSE: To determine whether the beneficial effects of acetazolamide (ACZ) in improving vision at 6 months continues to month 12 in participants of the Idiopathic Intracranial Hypertension Treatment Trial (IIHTT). DESIGN: non-randomized clinical study METHODS: In the IIHTT, subjects were randomly assigned to placebo-plus-diet or maximally tolerated dosage of acetazolamide-plus-diet. At 6 months subjects transitioned from study drug to ACZ. This resulted in the following groups 1) ACZ to ACZ; n = 34; 2) placebo to ACZ; n = 35; 3) ACZ to no treatment; n = 16; and 4) placebo to no treatment; n = 11...

INTRODUCTION: The annual incidence of intracranial aneurysm in Malaysia is estimated to be 1.1-1.7 per 100,000 population based on a study done conducted in 1988. Since then, little epidemiological research has been conducted in Malaysia, and the real incidence is therefore probably unreported despite advancements in the diagnosis and treatment of this disorder. Intracranial aneurysm may be treated by microsurgical clipping or embolisation depending on its location and the surgeon's preference...

BACKGROUND: Idiopathic intracranial hypertension (IIH) is characterized by increased cerebrospinal fluid (CSF) pressure and normal or slit ventricles. Lumboperitoneal shunting had been favored by many investigators for CSF diversion in IIH for decades; however, it has been associated with various side effects. Because of the small ventricular size adequate positioning of a ventricular catheter is challenging. OBJECTIVES: Here, we investigated the usefulness of electromagnetic (EM)-guided ventricular catheter placement for ventriculoperitoneal shunting in IIH...

BACKGROUND: Although size is one of the strongest predictors, small aneurysms often rupture. We compared the characteristics of small and large ruptured intracranial aneurysms (RIAs) according to their location to find the factors associated with small RIAs in each location. METHODS: Patients with subarachnoid hemorrhage due to saccular RIAs were consecutively enrolled. The sizes were dichotomized as small (<5 mm) or large, and the location was classified as paraclinoid-distal internal carotid artery, sidewalls of anterior or middle cerebral artery (MCA; sidewall), MCA-bifurcation, anterior or posterior communicating artery (Acom or Pcom, respectively), and posterior circulation RIAs...

BACKGROUND: Venous sinus stenting is an emerging treatment for patients with idiopathic intracranial hypertension and evidence of venous stenosis. Stents placed across the transverse and sigmoid sinuses often cover the vein of Labbé (VOL), a major anastomotic vein draining the cerebral hemisphere. The patency of the VOL after stenting and its clinical implications are poorly understood. METHODS: A retrospective analysis was performed of a prospectively collected database of patients undergoing venous sinus stenting...

OBJECTIVE The most frequent procedural complication of the endovascular treatment of intracranial aneurysms is a thromboembolic event (TEE); in a subset of patients, such events will cause permanent neurological disability. In patients with unruptured aneurysms, increasing evidence supports the use of periprocedural antiplatelet therapy to prevent TEEs. The object of this study was to evaluate whether patients with ruptured aneurysms and subarachnoid hemorrhage would also benefit from periprocedural antiplatelet therapy...

PURPOSE: During the process of tracheal intubation, patients are apneic or hypoventilating and are at risk of becoming hypoxemic. This risk is especially high in patients with acute or chronic respiratory failure and accompanying compromised respiratory reserve. To address this concern, apneic oxygenation can be administered during tracheal intubation to aid in maintaining arterial oxygen saturation. The objective of this narrative review is to examine the utilization of apneic oxygenation within the operating room, intensive care unit (ICU), emergency department, and pre-hospital settings and to determine its efficacy compared with controls...

INTRODUCTION: The role of N-terminal pro-brain natriuretic peptide (NT-proBNP) in patients with hypertensive intracerebral hemorrhage (HICH) is poorly understood. This study aimed to investigate the secretion pattern of NT-proBNP in patients with HICH and to assess its relationship with hematoma size, hyponatremia, and intracranial pressure (ICP). METHODS: This prospective study enrolled 147 isolated patients with HICH. Blood samples were obtained from each patient, and values of serum NT-proBNP, hematoma size, blood sodium, and ICP were collected for each patient...
