Filter by:Introduction Remote cerebral hemorrhage following reperfusion treatment in ischemic stroke is rare (1.3-3.7% of all treated strokes) and is associated with worse functional and vital prognosis. Multicenter observational studies suggest that amyloid angiopathy may be one of the main risk factors for remote hemorrhage. Currently, it is unknown what happens to those patients with remote hemorrhage beyond 3 months of follow-up in terms of risk/benefit balance when receiving antiplatelet or anticoagulant therapy, as well as from a cognitive point of view. Considering an analogy with amyloid angiopathy, the hypothesis is that those patients with remote hemorrhage have a higher risk of intracranial hemorrhage during follow-up when receiving stroke secondary prevention, and will also present greater cognitive deterioration during long-term follow-up. Main Objectives - To explore the frequency and risk factors for intracranial hemorrhage during follow-up of patients with remote cerebral hemorrhage. - To explore the frequency and progression of cognitive deterioration during follow-up in patients with remote cerebral hemorrhage. Methodology Observational, prospective, multicenter registry with a population-based case-control design of consecutive patients with remote hemorrhage following reperfusion therapy in acute ischemic stroke. Inclusion criteria: Diagnosis of ischemic stroke with age greater than or equal to 18 years who has remote cerebral hemorrhage after receiving reperfusion therapy in the acute phase. Exclusion criteria: Lack of basic data (age, sex, neuroimaging data) or telephone for follow-up. The cases will be those patients with remote hemorrhage. For each case included, 4 consecutive controls will be included (2 with local parenchymal hemorrhagic transformation and 2 without hemorrhagic transformation). The data will be filled out within the (Codi Ictus de CATalunya) CICAT registry form (currently mandatory in all stroke centers in Catalonia) to which additional variables will be added. Telephone follow-up will be conducted at 3, 12, and 24 months. Main study variable: - Any type of spontaneous or traumatic intracranial hemorrhage during a 24-month follow-up. - Score on the "Short Informant Questionnaire" scale (a validated 17-question questionnaire to be conducted over the phone, where a score higher than 57 points indicates cognitive impairment). Expected sample size during a 2-year recruitment period: 105-300 patients (considering the participating centers to date). Additional information. This study is endorsed by the "Pla Director de la Malaltia Vascular Cerebral" in Catalonia. Participating Centers. Participation offers have been sent to the 28 hospitals in the hospital network of Catalonia with the capacity to administer intravenous fibrinolysis. Positive responses have been received from 13 of them so far. In case the project is accepted by the (Comité Ético de Investigación Clínica) CEIC Sant Pau, the centers that have not responded will be contacted again to obtain their participation.
The goal of this experimental observation study is to figure out differently expressed biomarkers in lesion tissues in traumatic brain injury or hypertension intracranial hemorrhage patients. The main questions it aims to answer is: - Which RNA, protein and metabolites are differently expressed in lesion tissues? - What molecular mechanism is participated in TBI or ICH? Participants will be treated by emergency operation, and their lesion tissues will be collected during the operation.
Background: Despite the capability of emergency surgery to reduce the mortality of severe spontaneous intracranial hemorrhage (SSICH) patients, the effect and safety of surgical treatment for severe spontaneous intracranial hemorrhage (SSICH) patients receiving long-term oral antiplatelet treatment (LOAPT) remains unclear. In consideration of this, the cohort study is aimed at figuring out the effect and safety of emergency surgery for SSICH patients on LOAPT. Methods: As a multicenter and prospective cohort study, it will be conducted across 7 representative clinical centers. Starting in September 2019, the observation is scheduled to be completed by December 2022, with a total of 450 SSIC H patients recruited. The information on clinical, radiological, and laboratory practices will be recorded objectively. All of the patients will be monitored until death or 6 months after the occurrence of primary hemorrhage. Results: In this study, two comparative cohorts and an observational cohort will be set up. The primary outcome is the effect of emergency surgery, which is subject to assessment using the total mortality and comparison in the survival rate of SSICH patients on LOAPT between surgical treatment and conservative treatment. The second outcome is the safety of surgery, with the postoperative hemorrhagic complication which is compared between the operated SSICH patients on and not on LOAPT. Based on the observation of the characteristics and outcome of SSICH patients on LOAPT, the ischemic events after discontinuing LOAPT will be further addressed, and the coagulation function assessment system for operated SSICH patients on LOAPT will be established. Conclusions: In this study, we will investigate the effect and safety of emergency surgery for SSICH patients on LOAPT, which will provide an evidence for management in the future.
As one of the most serious forms of acute stroke, the early mortality rate of intracerebral hemorrhage(ICH) can be as high as 30-40%. The incidence of intracerebral hemorrhage increases with the increase of age. Under the circumstance of the aggravation of aging in China, intracerebral hemorrhage brings a certain burden to families and society. The results of several studies in recent years have failed to provide new therapeutic approaches for the treatment of cerebral hemorrhage. Therefore, novel therapeutic approaches is urgently needed for ICH. Primary and secondary prevention, acute inpatient care, and poststroke rehabilitation are all critical. The objective of this cohort study is to explore factors that might influence the long-term prognosis of patients with ICH and to further identify new potential targets for intervention.
In this project the investigators study the safety and efficacy of the pipeline embolization device with vantage technology in treatment of unruptured brain aneurysms
This study has two main goals: 1) to refine and enhance the R2R-TBI intervention; and 2) to examine the efficacy of the R2R-TBI intervention in a randomized control trial. To achieve the second goal, we will employ a between-groups randomized treatment design with repeated measures at baseline, one-month post-randomization, and at a six-month follow-up. The two conditions will be: a) usual medical care plus access to internet resources regarding pediatric brain injury (Internet Resources Comparison group, IRC), and b) usual medical care plus the R2R-TBI intervention (Road-to-Recovery group, R2R-TBI).
Abstract Purpose Patients with anticoagulation therapy has a higher risk of developing traumatic Intracranial Hemorrhage (tICH). Delayed Intracranial Hemorrhage (d-ICH) is a rarer clinical manifestation; however, the incidence varies from 0-9,6 % in other studies. Some studies have also questioned the clinical relevance of d-ICH, since the mortality and the need of neurosurgical intervention is reported to be very low. The aim of this study is to determine the incidence of d-ICH at Sundsvall Regional Hospital. Methods A retrospective observational study of patients with mTBI and oral anticoagulation therapy. Data from medical records and radiology registry in Sundsvall hospital for 29 months during 2018-2020 in Sundsvall identified 249 patients with an initial negative CT scan who performed a follow-up CT scan. Outcome measure was incidence of d-ICH.
Management of traumatic brain injuries causes significant efforts on emergency departments (ED) and overall health care. Patients on antithrombotic treatment with even minor trauma to the head, although without significant clinical findings, represent special challenges because the risk of traumatic intracranial hemorrhage (tICH) with these agents. The aim of this study was to compare the prevalence of tICH in patients on various pre-injury antithrombotic treatment exposed to minor Traumatic Brain injuries (mTBI) in Sundsvall with untreated patients. Secondary aim was to explore different risk factors for tICH. Data from medical records and radiology registry with mTBI in Sundsvall hospital between 2018-2020 in Sundsvall identified 2044 patients. Demographic data, pre-injury medications with antithrombotic treatment, state of consciousness at admission and the results of CT-scans of brain was investigated.
The purpose of this study is to determine the efficacy and safety of remote ischemic conditioning in treating acute intracerebral hemorrhage.
This study is the first and largest secondary prevention trial about lipid-lowering therapy for acute ischemic stroke patients at high-risk of intracranial hemorrhage. The primary hypothesis of this study is: excessive reduction in serum lipid levels by intensive statin therapy in acute ischemic stroke patients with cerebral microbleeds can increase the risk of intracranial hemorrhage. This study will shed light on new clinical decisions regarding the long-term serum lipid management in these patients with dilemma in clinical practice.
