Filter by:Plastic particles are a ubiquitous pollutant in the living environment and food chain, so far, plenty of studies have reported the internal exposure of microplastics and nanoplastics in human tissues and enclosed body fluids. Neurosurgery is the only department that can open the skull. In addition to blood and cerebrospinal fluid, there are brain tissue and tumors in the presence of lesions. Whether any of these microplastics and nanoplastics are present remains a mystery. This prospective observational study will harvest biological samples of neurosurgery patients. The objective of this research is to be able to detect microplastics and nanoplastics on blood and operation samples of neurosurgery patients.
The use of intracranial stents expands the possibilities for endovascular treatment of intracranial aneurysms and improves the success rate. However, it also increases the risk of ischemic complications in patients. The current standard dual antiplatelet regimen is considered crucial in reducing thrombotic events. Nevertheless, some patients exhibit resistance to antiplatelet drugs, which puts them at a higher risk of thrombotic events. In clinical practice, there is a lack of standardized platelet function testing and consensus on adjusting antiplatelet drug programs. This study conducted a multi-center, prospective cluster randomized controlled trial to investigate whether antiplatelet adjustment therapy guided by light transmittance aggregometry (LTA) detection can decrease the occurrence of ischemic events after stent implantation in patients with unruptured intracranial aneurysms. Additionally, the study aimed to establish a set of standardized antiplatelet regimens.
the goal of this clinical trail is to evaluate the clinical efficiency of intracranial aneurysm assistive software in the morphological measurement. The trail is designed as retrospective, multicenter, controlled clinical trail. Collecting probable cases images retrospectively according to inclusion criteria and exclusion criteria strictly. Controlling bias strictly, to make sure the measurement of intracranial aneurysm assistive software is evaluated reliably and precisely. In our trail, six physicions were recruited, containing three neuroradiologists, two radiologists and a residents. Software-assistant planning controls against no software-assisant planning，which aims to evaluate the improvement of morphological measurement efficiency of physicians.
To assess the expression of miRNA in patients with TAA, AAA in aneurysmatic tissue and to compare this expression with the healthy tissue in the same patient. In the same cohort, to asses the presence of miRNA in plasma and to compare with the control group. Over the period of three years,to follow subjects in order to assess if the presence of certain miRNAs speeds up or slows down the progression of disease. In patients with intracranial aneurysms to detect miRNA in plasma especially in patients with familial occurrence.
The objective of this clinical investigation is to evaluate the safety and technical success of the Basecamp Vascular controllable directional GECKO guidewire when used to facilitate endovascular access to the targeted vessel in order to treat the vascular lesion.
This is a monocentric randomized prospective trial comparing 2 different endovascular strategies of intracranial arterial angioplasty in case of refractory intracranial arterial vasospastic stenosis : - chemical angioplasty - chemical and mechanical angioplasty
Endovascular coiling has become a strategy of choice of intracranial aneurysms due to its minimally invasiveness. However, there has few prospective randomized controlled studies on the comparison of therapeutic effect between endovascular coiling and microsurgical clipping, especially the latter via keyhole approaches, which has been widely used in recent years. Based on the data of a single center, a randomized controlled study was conducted on patients with ruptured anterior circulation aneurysms suitable for both endovascular and extravascular treatment, including endovascular coiling, microsurgical clipping via conventional craniotomy and keyhole approaches, in order to compare the efficacy of the above strategies and provide more objective basis for treatment selection for operators.
An aneurysm is a bulge in a blood vessel caused by a weakness in the blood vessel wall, usually where it branches. As blood passes through the weakened blood vessel, the blood pressure causes a small area to bulge outwards like a balloon. Most brain aneurysms only cause noticeable symptoms if they burst (rupture). This leads to an extremely serious condition known as a subarachnoid hemorrhage, where bleeding caused by the ruptured aneurysm can cause extensive brain damage and symptoms. The study aims to evaluate the safety and effectiveness of a medical device to treat brain aneurysms.
In this study, 20 regional neurosurgery centers across the country will be included, and the study cohort will be constructed on the basis of the IARP-CP cohort.The artificial intelligence platform was used to analyze the clinical, morphological, hemodynamics, aneurysm wall characteristics and other factors of unruptured aneurysms, as well as the relationship between these factors and the risk of aneurysm instability, seek the potential risk factors, and finally establish a multi-dimensional prediction model of rupture risk of intracranial aneurysms.
This study is a multi-center, single arm, open label, retrospective and prospective clinical data collection of CascadeTM, Non-Occlusive Remodeling Net, in adults with intracranial aneurysms, demonstrating the effectiveness and safety of the CascadeTM in providing temporary assistance for coil embolization of intracranial aneurysms. All consecutive eligible patients from all participating sites will be included in this clinical data collection. The relevant data of the coil embolization procedure will be collected via an eCRF system. Peri procedural data on the coil embolization procedure as well as discharge, 30 days and at 3-6 months status will be collected.
