Filter by:This prospective single-center cohort study aims to identify the incidence of cognitive dysfunction after unruptured aneurysm operation and explore the influencing factors. The primary end point is the cognitive dysfunction at 6 months after operation.The features of cognitive function, mental status, neurological function recovery, and quality of life of patients with unruptured intracranial aneurysms at different time points would be analyzed.
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.
Gingival recession is defined as the apical migration of the gingival margin from the amelocemental junction. This condition may be associated with symptoms such as tooth hypersensitivity, root decay, and cosmetic complaints from patients. Many treatments have been used to treat gingival recession and the gold standard is the autogenous connective tissue gingival graft because of its predictability. This type of gingival graft is performed by harvesting connective tissue from patients' hard palate. Periodontists and general dentists frequently perform these gingival grafts. Occasionally, some patients develop postoperative complications that need to be addressed in an hospital setting. An uncommon but concerning complication of an autogenous connective tissue gingival graft is a donor site pseudoaneurysm of the greater palatine artery. No description of this complication following a gingival graft has been identified in the current literature. One case report mentioned that pseudoaneurysm of the greater palatine artery looks like a pulsatile nodule associated or not with pain on palpation. From the experience of the investigators, patients may consult an hospital setting having a complaint of major oral bleeding. Local hemostatic agents can palliate this type of bleeding, but angiographic embolization is often required. Several cases were treated in the investigators' hospital. Thus, the investigators believe it is relevant to share this experience with the scientific community. The primary objective of this case series is to inform dental professionals of the existence and the management of postoperative pseudoaneurysm of the greater palatine artery following autogenous gingival graft. The secondary objective is to find potential solutions to minimize the incidence of this morbid complication.
This study is a data linkage project within which we aim to model the impact on the NHS AAA Screening programme of a targeted approach to screening by targeting men who smoke. This in-silico study will generate a hypothetical population based on primary care datasets with known outcomes from screening (we know which men have an aneurysm and who do not) to determine the feasibility and safety of this approach.

IgG4 Related Disease is a multi-systemic fibroenophilic disease that includes a basket of recently discovered medical conditions. The properties that bind them are: lesions similar to tumors in the mixed organs, lymphoplasms filtrate enriched with plasma IgG4 positive cells, storiform fibrosis, and often, but not always, a high level of IgG4 in the serum. This disease has been on the rise for the past two decades and since its recognition in 2001 there has been impressive progress in understanding its various manifestations, so that today almost every body system can be involved. One of the conditions associated with this disease is oritis / periortitis and 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.
Rupture of abdominal aortic aneurysms(AAA) causes 12,000 deaths/year in the UK.1 Elective repair to prevent this carries a perioperative mortality of 4.5% for open surgery and 1% for endovascular repair. This risk is associated with poor cardiorespiratory fitness which can be measured using Cardiopulmonary Exercise Testing(CPET) with the CPET variables, peak oxygen uptake(peakVO2)<15ml/kg/min and anaerobic threshold(AT)<10.2ml/kg/min identifying patients at increased risk of early death after AAA repair.3 These variables can therefore be used as surrogate markers for cardiovascular fitness and risk of mortality and morbidity in AAA surgery; optimising these markers should improve fitness and decrease this risk. The optimal duration and type of exercise training for improving peak VO2 and AT in AAA patients is not known. AAA patients are unique as they are motivated to reduce the risk of impending surgery but are afforded the time to improve their fitness as repair may not be needed for months or even years. The investigators propose a pilot randomised controlled trial to explore the effectiveness of a 20-week community (either home or gym-based) exercise programme to achieve sustained improvements in peak VO2 and AT, as measured by CPET, in AAA patients. Changes in QoL, habitual activity levels and cardiovascular risk will also be assessed. The results will inform a definitive multicentre clinical trial on exercise to improve outcomes in elderly patients with cardiovascular disease and AAA.
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.
