Filter by:This is a study looking at a new way to evaluate vascular problems or tumors in brain surgery patients using a standard & approved intravenous dye and augmented reality.
The purpose of this study is to assess the safety and effectiveness of the Pipeline™ Vantage Embolization Device with Shield Technology™ in the treatment of intracranial aneurysms within the intended indication for use.
- Give an effective treatment for intracranial wide necked aneurysm and can detect the best method could be used. - Improve the outcome of these patients and decease rate of recurrence and complications.
The study is an observational, European, multi-center, prospective assessment of the clinical utility of the 0.017 WEB Aneurysm Embolization System in subjects with intracranial aneurysms deemed appropriate for endovascular treatment.
Patient Power is a patient research network and database (registry) to collect prospective information about demographics, self-reported diagnoses and medications, and willingness to participate in research from participants with rheumatoid arthritis (RA), spondyloarthritis (SpA), other musculoskeletal conditions, chronic neurological conditions like migraine, chronic pulmonary conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, autoimmune dermatological conditions such as psoriasis, and other chronic inflammatory or immune-mediated conditions. In addition, since patients with chronic conditions often have other co-morbidities like cardiovascular health and obesity-related metabolic disorders, these conditions will also be included. Participants will provide information from their smartphones or personal computers. The information will be used by researchers and clinicians to help patients and their providers make better, more informed decisions about treatment of chronic conditions.
Pipeline TM embolization device launched to China in 2014, and has been widely used to treat large width IA. Therefore, it is necessary to collect and analysis the clinical data to evaluate effectiveness and safety of its usage in Chinese population, and this may guide the clinical practice and meet the clinical needs better.
Cerebral aneurysm surgery has significant mortality and morbidity rate. Inflammation plays a key role in the pathogenesis of intracranial aneurysms, their rupture, subarachnoid haemorrhage and neurologic complications. Brain injury activates immune cells and triggers cytokine release. Cytokine level in blood and cerebrospinal fluid is an indicator of inflammatory response. Cytokines contribute to secondary brain injury and can worsen the outcome of the treatment. Preventing secondary brain injury by modulating inflammatory response represents a therapeutic target. Lidocaine is local anesthetic that can be used in neurosurgery for regional anesthesia of the scalp and for topical anesthesia of the throat prior to direct laryngoscopy and endotracheal intubation. Except analgetic, lidocaine has systemic anti-inflammatory and neuroprotective effect. It acts through several mechanisms on various types of immune cells producing immunosuppressing effect. Lidocaine can act on activated microglia within central nervous system causing attenuation of immune response. Primary aim of this prospective randomized trial is to determine influence of lidocaine administration on inflammatory cytokine levels in serum and cerebrospinal fluid during and following cerebral aneurysm surgery. Secondary aim is to determine possible correlation between levels of cytokines and incidence of neurologic and infectious postoperative complications. For that purpose, postoperative neurological clinical status will be recorded. Signs of vasospasm and pathological postoperative brain CT scan findings will be recorded. Incidence of meningitis, pneumonia and sepsis in postoperative period will also be analyzed. Hypothesis of this trial is that lidocaine administration during cerebral aneurysm surgery would significantly change levels of pro-inflammatory cytokines in cerebrospinal fluid and serum. Lower concentrations of pro-inflammatory cytokines can possibly contribute to better outcome and significantly lower incidence of postoperative complications. Enzyme-immunochemical analysis will be used to measure levels of interleukin-1β, interleukin-6 and tumor necrosis factor-α in cerebrospinal fluid and serum. Investigation group will have, during cerebrovascular surgery under general anesthesia, regional anesthesia of the scalp and topical anesthesia of the throat prior to laryngoscopy, all done with lidocaine. Control group will have general anesthesia without lidocaine administration.
This observational, retrospective, single-arm, multi-centre cohort study will use real-world data (RWD) to develop real-world evidence (RWE) of the safety and clinical effectiveness of the Pipeline™ Flex Embolization Device with Shield Technology™ in Australian patients that have received a flow diversion device to treat an intracranial aneurysm (IA). The medical records from 500 procedures completed at Gold Coast University Hospital in Queensland (QLD), Prince of Wales Hospital in New South Wales (NSW), and Sir Charles Gardiner Hospital in Western Australia (WA), will be analysed. The study will report the risk and likelihood of stroke (ischaemic and haemorrhagic), delayed neurological adverse events and incomplete aneurysm occlusion within sub-groups of the patient cohort and determine the predictive or confounding factors that influence clinical outcomes under pragmatic or 'real-world' conditions.
The purpose of this study is to learn about protecting the brain from low blood flow (ischemia) with limb preconditioning. From human studies the investigators know that the brain can be protected from dangerous low blood flow by reducing the blood flow to an arm or leg for just a short period of time. This is called limb preconditioning. The investigators are studying the safety and feasibility of preconditioning and their effect of protecting the brain from ischemia in two different groups. This is a Phase 2, randomized, double-blind, sham-controlled, design. Up to 50 male and female patients undergoing elective endovascular repair of unruptured brain aneurysm who are randomized to the remote ischemic preconditioned or sham group will be enrolled. This study consists of one 3-9 month study period for each patient plus up to 14 days for enrollment activities. Subjects are required to return between 3-9 months for end-of-study procedures.
Despite the theoretical benefits of i.v. agents, volatile agents remain popular. In a study comparing desflurane, isoflurane, and sevoflurane in a porcine model of intracranial hypertension, at equipotent doses and normocapnia, cerebral blood flow (CBF) and ICP were least with sevoflurane. Propofol is the most commonly used intravenous anesthetic. It has many theoretical advantages by reducing cerebral blood volume (CBV) and ICP and preserving both autoregulation and vascular reactivity. Neurosurgical patients anaesthetized with propofol were found to have lower ICP and higher CPP than those anaesthetized with isoflurane or sevoflurane. The well known pharmacodynamic advantages of intravenous anesthetics may give this group of drugs superior cerebral effects when compared with inhalation anesthetics.
