We report our results using Onyx HD-500 (Micro Therapeutics, Inc., Irvine, CA) in the endovascular treatment of wide-neck intracranial aneurysms, which have a high rate incomplete occlusion and recanalization with platinum coils. Sixty-nine patients 84 aneurysms were treated. Most located anterior circulation (80 aneurysms), unruptured (74 incidental. Ten presented subarachnoid hemorrhage, 15 symptomatic. All had wide necks (neck >4 mm and/or dome-to-neck ratio <1.5). Fifty small (<12 mm),...
The molecular mechanisms behind aneurysmal subarachnoid haemorrhage (aSAH) are still poorly understood. Expression patterns of miRNAs may help elucidate the post-transcriptional gene expression in aSAH. Here, we evaluate global profile (miRnome) patients with aSAH to identify potential biomarkers. We collected 33 peripheral blood samples (27 cerebral aneurysm, 7 10 days after haemorrhage, when usually is vasospasm risk peak, and six controls). Then, were performed small RNA sequencing using...
Background: There are no studies describing the cerebral hemodynamic patterns that can occur in traumatic brain injury (TBI) patients following decompressive craniectomy (DC). Such data have potentially clinical importance for guiding treatment. The objective of this study was to investigate postoperative patterns, using transcranial Doppler (TCD) ultrasonography, who underwent DC. relationship between circulatory and patients' outcome also analyzed. Methods: Nineteen TBI with uncontrolled...
Most of the Brazilian population relies on public healthcare and stroke is a major cause disability in this country continental dimensions. There limited information about access to rehabilitation after Brazil.To provide comprehensive Access Rehabilitation After discharge from hospitals Brazil (AReA study), up 6 months stroke.The present study intends collect 17 health centers 16 cities 5 macroregions country. Each center will include 36 participants (n = 612). The inclusion criteria are:...
Individuals with type 2 Neurofibromatosis are predisposed for the appearance of schwannomas. In present study we analyzed loss heterozygosity and mutations in NF2 gene patients sporadic Schwannoma without 2.We 39 spinal schwannoma. We quantified number alleles by FISH sequenced gene.We identified 16/39 point and/or LOHs tumor samples analyzed. The were found 7/39 patients. Two homozygous detected 4/39 tumors, presence mutation heterozygosis was revealed 3/39 two one allele gene, no...
Introduction . Cerebral emboli may occur in subarachnoid hemorrhage (SAH) and intracranial aneurysm surgery. Although embolic signs (ES) have been reported SAH, their origin remains unclear. The aim of this study was to report the detection ES during routine TCD monitoring patients with aneurysmal SAH. Methods A total 105 SAH were submitted evaluation. Patients monitored almost daily (5 times per week). In each session, one experienced operator performed detect or assess vasospasm arteries...
Title: Persistent post-traumatic orbital cerebrospinal fluid fistula with multiple episodes of meningitis: a systematic review and case reportBackground: Orbital (CSF) fistulas are very rare. Most these spontaneously heal within couple days usually do not require surgical repair. Furthermore, they present low rates complications. Case presentation: We report 15-year-old boy that suffered penetrating head trauma developed meningitis due to persistent nasal CSF fistula. He underwent different...
Headache as a chief complaint is rare in the paediatric emergency room. Actually, very seldom cases secondary to life threatening conditions non-traumatic subarachnoid haemorrhage have been reported. A child with severe headache and nuchal rigidity no other abnormalities on physical examination Magnetic resonance angiography cerebral disclosed ventricular arteriovenous malformation choroid plexus, supplied by anterior choroidal artery, classified according Spetzler grading system grade 3...
Brainstem abscess is a rare condition with variety of treatment approaches. In this paper, we report an unusual case brainstem positive outcome in immunocompetent patient who was treated antibiotic therapy.A 22-year-old female presented bilateral tetraparesis that worse on the left hemibody, appendicular tremor, and upper eyelid ptosis. Brain magnetic resonance imaging showed pons midbrain due to possible nocardiosis. She dexamethasone, phenytoin, vancomycin, meropenem for 8 weeks...
Describe a case of cerebral proliferative angiopathy in patient with disabling headaches which we noticed CPA lesion shrinkage the use betablocker. Report clinical details, radiographic and angiogram findings medical management based on MOOSE Guidelines. The described this paper is about young man who, at first, complained headache migraine characteristics. Headaches became disabling. According to international protocols for treatment migraine, prophylactic tricyclics beta-blockers...
Abstract Posterior circulation aneurysms represent 10–15% of intracranial aneurysms. The diagnosis is usually secondary to subarachnoid hemorrhage due its initial asymptomatic presentation and higher risk rupture compared with in the anterior circulation. surgical treatment posterior complex challenging for neurosurgeons because particular anatomy close relation brainstem cranial nerves also depth narrowness approach. Aneurysms from different locations have specific anatomical relationships...
A esclerose medial temporal (EMT) é caracterizada pela hipocampal e diferentes graus de acometimento das estruturas vizinhas como amígdala, giro parahipocampal córtex entorrinal. O estudo avaliou 40 indivíduos com EMT do grupo controle. Os casos foram avaliados por um método para as medidas da ínsula (E-Film) outro o cálculo volume (Neuroline). Não houve diferença estatística alteração lobo nos pacientes portadores EMT. não demonstrou morfológica quando comparado os dois grupos.
Background: Brain arteriovenous malformation (BAVM) are vascular lesions described as anomalous tangle of vessels in which arteries and veins directly connected without an intervening capillary system normal brain tissue. When its presentation comes with disrupt leads to serious neurological impairment or death. This feature can be associated a biological molecular expression change the natural history AVM. By this way special focus on miRNA profile explain metabolic route trace diagnostic...
