Filter by:Ruptured intracranial aneurysms is currently a common disease that seriously affects human health and quality of life due to its high morbidity,high mortality and high disability. At present,Ruptured intracranial aneurysms are treated with craniotomy clipping and interventional embolization ,but for ruptured wide-neck intracranial aneurysms, the treatment of craniotomy clipping and coiling embolization are not effective.With the improvement of endovascular treatment materials and techniques, three dimensional coil basket technique, double microcatheter technique, balloon assisted ONYX embolization, simple stent covered aneurysm neck, balloon or stent assisted neck remodeling and coil embolization are used in endovascular treatment of ruptured wide-neck intracranial aneurysms. The treatment methods are different in the intervention effect of ruptured wide-neck intracranial aneurysms, for example, the complications of interventional therapy are lower than craniotomy clipping,but the rate of well functional outcome (mRS ≤2) differed significantly by 3 months follow-up (65.0% vs.75.0%), and there is not standard of treatment in different parts of ruptured wide-neck intracranial aneurysms in our country, the choice of interventional therapy or craniotomy clipping are different in different clinical centers; on the other hand, there are serious problems in the treatment of ruptured wide-neck intracranial aneurysms, because without the relevant guidelines of diagnosis and treatment of ruptured wide-neck intracranial aneurysms, different clinical centers will cause excessive treatment of ruptured wide-neck intracranial aneurysms, not only bring unreasonable utilization of medical resources, but also cause the subject's life and property to be threatened. The patients with ruptured wide-neck intracranial aneurysms(n=1084) and unruptured intracranial aneurysms(n=300) were included in prospective cohort study, after interventional therapy and craniotomy clipping, setting fixed time for postoperative follow-up, the clinical data and image data were recorded, the safety, efficacy and economic benefits of interventional treatment and craniotomy clipping were compared, providing strategies for the standardized treatment of ruptured wide-neck intracranial aneurysms.
To assess safety and efficacy of pCONUS2 for the treatment of wide neck bifurcation aneurysms.
This is a registry study of the natural course of unruptured intracranial aneurysms (UIA). In addition, the investigators will analyze the benefit-risk of antithrombotic or anticoagulant therapy in patients with unruptured intracranial aneurysms associated with ischemic heart disease or ischemic cerebrovascular disease. The investigators aim to use research data to create a China national database of UIA
Un-ruptured intracranial aneurysm is a complex disease that seriously affects human life and health. At present, the treatment of intracranial aneurysm is divided into interventional treatment and craniotomy clipping, the two treatment methods are different in the intervention effect of aneurysm, for example, the complications of interventional therapy are lower than craniotomy clipping, but the long-term patency rate is lower than craniotomy clipping, and there is no standard of treatment in different parts of aneurysm in our country, the choice of intervention measures of un-ruptured aneurysm is different in different clinical centers; on the other hand, there are serious problems in the treatment of aneurysms, because without the relevant guidelines of diagnosis and treatment of intracranial aneurysms, different clinical centers will cause excessive treatment of un-ruptured aneurysms, not only bring unreasonable utilization of medical resources, but also cause the subject's life and property to be threatened. The patients with un-ruptured intracranial aneurysm(n=1500) were included in prospective cohort study, after clipping and intervention operation, setting fixed time for postoperative follow-up, the clinical data and image data were recorded, the safety, efficacy and economic benefits of interventional treatment and craniotomy clipping were compared, providing strategies for the standardized treatment of un-ruptured intracranial aneurysms.
Intracranial aneurysms are common in the general population. The overall prevalence of unruptured intracranial aneurysms (UIAs) is estimated of 2.3-3.2% in the population without specific risk factors for SAH. As noninvasive imaging modalities are more commonly used than before, UIAs are increasingly being detected. Most patients with small aneurysms (less than 5mm) are incidentally found in clinical practice. Some studies indicate that the majority of patients with UIAs, particularly with small aneurysms (<7mm), have a low risk of rupture, and others have found that small ruptured aneurysms have a high proportion in patients with SAH. Therefore, there is a lot of controversy regarding which small aneurysms can be left untreated, or which aneurysms are needed to be treated with clipping or coiling. The prevalence varies widely among different detection methods, race/ethnicity or patients with other inherited diseases. Although a wealth of data is available for the natural history of UIAs, the true natural history remains unknown because case selection bias occur in almost all studies. However, data on Chinese UIA is unknown. Using the MR angiography (MRA) to detect aneurysms, the prevalence is 7% of selected adult population in China. Therefore, small UIAs are very common and are increasingly being detected in clinical practice. Conservative treatment, surgical clipping and endovascular coiling are the three treatment options for UIAs. The optimal treatment remains controversial, particularly for small aneurysms (less than 7mm). To date, no clinical trials have compared the safety and efficacy between conservative treatment and surgical clipping or endovascular coiling for UIAs. It may be impossible to conduct the randomized controlled study considering aneurysm ruptured as a devastating event. However, surgical clipping or endovascular treatment itself carries a risk of immediate morbidity or mortality. Therefore, a substantial variability widely exists in treatment decision-making for UIAs, and this may lead to a great variability in clinical recommendations. Our study is a prospective observational study to identify the incidence of rupture of small aneurysms in the first year after the diagnosis of the aneurysm which is left untreated. Meanwhile, we determine the differences of outcomes, procedural complications, and rates of retreatment between surgical clipping and endovascular coiling for small UIAs in China.
Recently, the occurrence and potential impact of pituitary dysfunction after aSAH has gained increasing interest. Several studies have demonstrated pituitary dysfunction after SAH suggesting that pituitary dysfunction may be a contributing factor for residual symptoms after SAH. This is an observational multicentric study aimed to test the prevalence of thyroid abnormalities, other neuroendocrinological dysfunction and their influence on outcome of patients affected by aSAH.
The purpose of this study is to evaluate the effectiveness, long-term safety and explore the safety and efficacy factors WILLIS™ intracranial stent graft system in clinical applications.
Patients' responses to oral antiplatelet therapy are subject to variation. Bedside monitoring offers the opportunity to improve outcomes of intracranial aneurysm patients undergoing stent deployment by individualizing therapy.This trial is designed to demonstrate the superiority of a strategy of platelet function monitoring with dose adjustment in suboptimal responders as compared to a more conventional strategy without monitoring and without dose adjustment to reduce the primary end point evaluated 6 months after stent deployment in patients with intracranial aneurysms.
