Venous tinnitus (VT) is seriously affecting the quality of life of five million patients in China. Bony wall reconstruction is the main treatment method, but the postoperative recurrence rate exceeds 30%, and the specific mechanism is unclear. Based on our previous work, a scientific hypothesis was put forward: the key to the recurrence of V T is pathologic remodeling of the peri-sinus bony wall mediated by the venous sinus morphology, blood flow, and pressure after surgical reconstruction. As a continuation of the National Natural Science Foundation of China-Youth Project, this project intends to combine multimodal imaging technology, multiphysics coupled numerical model and machine learning method to analyze analyze the data after bone wall reconstruction in multiple dimensions: ① To explore the influence of peri-sinus bony wall morphology, venous sinus morphology, intra-sinus blood flow, intra-sinus pressure, and cerebral perfusion on the recurrence of VT using ultra-high resolution CT, vessel wall MR, 4D Flow MR and ASL MR imaging technology; ② To explore the influence of blood flow impact, sinus wall pressure and peri-sinus bone wall deformation on the recurrence of VT using multiphysics coupling numerical model with vessel, blood flow, bone and acoustic fields; ③ To determine the risk factors and their weights of VT recurrence using machine learning methods, and to establish a personalized surgical planning and prognostic evaluation models; Thus, to verify the hemodynamic and biomechanical mechanisms of VPT recurrence to achieve personalized and effectively treatment. This project may prevent and warn the recurrence of VPT after bony wall reconstruction.
The goal of this randomized trial to assess the angiographic efficacy of venous stenting in dural arteriovenous fistulae (DAVF) via improvment on Cognard's Classification as compared to no intervention at 6 months Participants belonging to experimental group will be treated using venous stenting. DAVF will be assessed by angiography at 6 months follow-up. Participants belonging to control group will be followed accordingly to standard of care (no treatment). After 6 months, control group patients can be treated by any means accordinlgly to standard of care.
This study seeks to pilot an evaluation of whether an external jugular vein compression collar approved by the US Food and Drug Administration (FDA) for contact sports can provide symptomatic relief of venous pulsatile tinnitus. Furthermore, the study will evaluate quality of life impacts of the device and adherence by users.
There have been few published studies that examine the efficacy and safety of endovascular treatments on patients with pulsatile tinnitus with venous stenosis. Despite the limited experience with venous sinus stenting to treat pulsatile tinnitus, preliminary results show that venous sinus stenting could represent a viable alternative for refractory pulsatile tinnitus patients with venous sinus stenosis. The purpose of this study is to evaluate the safety and efficacy of this procedure in a controlled fashion, using strict inclusion and exclusion criteria, and long-term clinical and imaging follow-up. The investigators hope to provide robust data regarding the safety and efficacy of venous sinus stenting for patients with pulsatile tinnitus.
The study objective is to compare the CBCT images generated by the CS 9300 to those generated by conventional CT.
