简要总结
The purpose of this research study is to collect data/measurements that are routinely collected in standard of care cerebral angiogram
详细描述
Research for this study is to determine how the injection of contrast material influences vessel measurements, as these measurements guide device selection when interventions are warranted.
The data will be used to determine if there is a significant change in vessel diameter with intra-arterial injection of contrast material in cerebral angiography, how changes in force of contrast injection augments the significance of the changes in vessel geometry, and the extent of propagation downstream from the catheter tip that such changes in vessel diameter are detected and found to be significant, as these changes could potentially lead to less optimal device selection by providing an overestimation of true vessel diameter.

结局指标
主要结局
Peak pressure associated with injection
时间窗: During procedure, up to 10 minutes
The effort force of injection will be measured and recorded for each run using a standard arterial line pressure transducer setup that attaches to the guide catheter, with data acquired via Mediocollector (a program that allows for quantitative recording of data. The duration of peak pressure will be collected.
