What is an acceptable deviation for flow rate in the Internal Carotid Artery during angiography?

The acceptable deviation for flow rate in the Internal Carotid Artery during angiography is defined based on the physiological norms for blood flow in this critical vessel. A range of 3.0 - 8.6 ml/sec is considered appropriate as it reflects normal physiological conditions while allowing for variations due to individual patient factors and the specifics of the imaging procedure.

Flow rates that fall within this range ensure that the angiographic assessment is effective and provides clear imaging without compromising the hemodynamics of the artery being evaluated. This range is likely derived from clinical studies and experiences that have established baseline conditions for blood flow under varying circumstances.

Understanding the significance of this range is vital for practitioners in interventional radiology, as it can influence decisions related to interventions, patient management, and the interpretation of angiographic findings. If flow rates deviate significantly from this range, it could indicate potential pathologies or require further investigation, emphasizing the importance of adhering to established standards during procedures.
