Filter by:Complex endovascular aortic repair in inflammatory and infective perivisceral abdominal aortic aneurysms and thoracoabdominal aortic aneurysms (CEVARII) study is a collaborative international effort among vascular surgeons to establish a database on the global experience in the management of INAAs and IAAs. Ethical approval for the study was obtained from the Colorado Multiple Institutional Review Board (COMIRB) under protocol number 23-1533.
Endovascular treatment has become one of the primary treatment methods for intracranial aneurysms. The unfavorable outcomes during follow-up included aneurysm recurrence and long-term incomplete-occlusion, which would bring a high risk of rebleeding and retreatment. Previous studies have tried to predict the outcomes of aneurysms following endovascular treatment based on aneurysm characteristics including morphology, embolization packing degree, etc, but the conclusion was inconsistent. Hemodynamics of aneurysms and parent artery played a greater role in predicting outcomes following endovascular treatments. Investigators also found that the outcomes were determined by many factors, in which the demography, clinical indicators, treatment methods, and material selection can not be ignored, and the mechanism of unfavorable imaging outcomes should be explored using large samples of clinical cases and numerous variable parameters. The pre-experiment of investigators confirmed that artificial intelligence technology can meet the calculation requirements for deep mining and analysis of large sample data. This study aims to use the deep learning model to identify relevant risk factors and weights, establish a stable and accurate prediction model, then incorporate the prospective study to verify the model. The results will be very helpful in accurately predicting the adverse outcomes such as recurrence and long-term non-occlusion after endovascular treatment and help to improve the therapeutic strategy and avoid risk factors. Besides, the occurrence of ischemic or hemorrhagic complications during follow-up may affect the final follow-up outcome, so the analysis was included as one of the outcome events to evaluate the prognosis after intervention.
To collect real-world evidence allowing assessment of functional, imaging, and safety outcomes of commercially available MicroVention devices used for the endovascular treatment of intracranial aneurysms (IA) at the direction of the treating physician.
The primary objective of ARISE II is to assess the safety and effectiveness of the GORE® Ascending Stent Graft device in the treatment of lesions involving the ascending aorta and aortic arch.
The purpose of the study was to evaluate the safety and efficacy of a branched type intraoperative stent system for the treatment of Stanford type A aortic dissection
The proposed study is a multi-center single arm retrospective and prospective data collection, of patients treated with the LVIS device of specific sizes of 3.5mm, 4.0mm, 4.5mm, 5.5mm with up to 5 years follow-up. Information collected during the study will be standardized across centers to include pre-treatment baseline characteristics of patients including aneurysm(s) symptoms, procedural information, prespecified clinical safety events of interest, and follow-up imaging, clinical visits or telephone calls.
Retrospective, single center, single arm PMCF study on the performance and safety of Lyoplant® used for the replacement and extension of connective tissue structures in neurosurgery.
The prospective, multicenter, single- arm study is designed to verify the safety and efficacy of pulsed sonic balloon dilatation catheter and pulsed sonic generater in the treatment of coronary calcification lesions.
The primary objective of this study is to collect data regarding the effectiveness of using the Enterprise 2 Reconstruction Device in successfully embolizing intracranial aneurysms with wide neck configuration.
This is an observational cohort study addressing the incidence of cerebral microemboli and alterations of cerebral hemodynamic physiology of the Relay®Branch thoracic stent-graft system.
