Objective of the study is to determine possibilities of intraoperative sonography in detecting of various brain mass lesions, assessing extent of their resection and define indications to use ultrasound-guided needle or ultrasound wire-guided port.
The purpose of the study is to assess accuracy, advantages of functional neuronavigation and calculate safe distance from motor areas to brain tumors and vascular malformations in image-guided surgery.
The purpose of the study is to calculate magnitude, type of intraoperative brain shift and assess possibility of it's prediction.
The purpose of this study is to investigate the role of multimodal CT in evaluating and predicting different clinical outcomes in patients with unruptured brain arteriovenous malformations with medical management alone. This study will be undertaken in the following aspects: 1. Morphological, structural and imaging histological signal analysis based on multimodal CT to explore the relationship between imaging features and different clinical outcomes of bAVMs. 2. Hemodynamic and flow pattern analysis of local and peripheral bAVMs based on multimodal CT to explore the association between blood flow features and different clinical outcomes. 3. Based on multimodal CT and deep learning algorithms to create an automated segmentation model for bAVMs and a prediction model for distinct clinical outcomes. The obtained patient information includes: Baseline information, CT, MRI, DSA (Optional), and follow-up information. Follow-up will be undertaken at 6 months, 12 months, 24 months and 36 months after enrollment with the following primary observation. Main observation endpoints: 1. Hemorrhage events associated with bAVMs 2. New epilepsy symptoms or exacerbations 3. New neurological dysfunction(including motor dysfunction, cognitive dysfunction, etc).
This is a single-center, prospective, single-arm clinical study to evaluate the feasibility, safety, and performance of VenoStent's SelfWrap® Bioabsorbable Perivascular Wrap on arteriovenous fistulas (AVFs). All participants are chronic kidney disease (CKD) patients already receiving hemodialysis treatments that are referred for creation of a new arteriovenous fistula (AVF).
In this case, we report a case of atresia syndrome (LIS), a serious neurological disease caused by pulmonary arteriovenous fistula (PAVM). We present a previously healthy middle-aged woman who developed atresia syndrome after severe pontine infarction due to basilar artery occlusion due to undiagnosed arteriovenous malformation. This report reviewed the medical history, post-admission examination and related literature, and concluded that PAVM should be considered as the cause of implicit stroke, especially in young patients with right-to-left shunt, and should be actively treated.
The study is an observational prospective evaluation of an approved and unchanged clinical management, evaluating different diagnosis methods to assess brain perfusion in patients with an aneurysmal or AVM-related intracranial hemorrhage
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
The purpose of this open-label study is to evaluate the safety and efficacy of cobimetinib in extracranial AVM.
