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).

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT05449106 |
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
