Filter by:This study aims to determine the inter- and intra-variability of Transcranial Doppler (TCD) ultrasound in neuro-critical care patients who are planned for consecutive daily TCD evaluations.
The objective of this study is to explore the effects of Sirolimus on the underlying molecular alterations of cerebral aneurysms.
Intracranial bifurcation aneurysms are commonly repaired with surgical and with endovascular techniques. Wide-necked bifurcation aneurysms (WNBA) are a difficult subset of aneurysms to successfully repair endovascularly, and a number of treatment adjuncts have been designed. One particularly promising innovation is the WEB (Woven EndoBridge), which permits placement of an intra-saccular flow diverting mesh across the aneurysm neck, but which does not require anti-platelet agent therapy. Currently, which treatment option leads to the best outcome for patients with WNBA remains unknown. There is a need to offer treatment with the WEB within the context of a randomized care trial, to patients currently presenting with aneurysms thought to be suitable for the WEB.
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.
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.
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.
In the stage of randomized controlled study, our purpose is to obtain the Intraoperative anticoagulation program supported by evidence-based medicine.
In the stage of registration study, our purpose is to find out the safety range of activated coagulation time level in cerebral aneurysm and arteriovenous malformations with hybrid operation.
Background: Earlier treatment and resolution for patients with cerebral aneurysms is now possible due to earlier diagnosis. This observational study aims to evaluate the intraoperative cardiovascular parameters in patients with cerebral aneurysms undergoing endovascular therapy. Method: This is an observational prospective study. Patients ≥ 18 years old diagnosed with an unruptured cerebral aneurysm or subarachnoid hemorrhage (SAH) (Hunt & Hess grade I or II) undergoing endovascular treatment under general anesthesia between April 2015 and February 2017 were included. Non-invasive measurements of hemodynamic variables were collected at six time points during the procedure (T1 to T6). Statistical analysis was performed by using central tendency measures for quantitative variables and absolute / relative frequency measurements for qualitative variables.
During surgery, electrophysiological signals will be acquired with the instrument (ISIS IOM, NeuroExplore, Software Version 4.4, Inomed) already in use at the Neurosurgery Service of the Neurocentro of the Hospital Civic Italian Switzerland in Lugano. Simultaneously to Somatosensorial Evoked Potential (SEP) will also be recorded the Electroencephalography (EEG) activity with the same detection of locations. For the purposes of the study the signals transmitted to the neurosurgeon through the hardware and the corresponding assessments done by the neurophysiologist responsible for intraoperative monitoring will be recorded. It will also be kept track of procedures performed during surgery.
