What is the flow rate for a single leg injection in peripheral pathology?

In interventional radiology, the flow rate for a single leg injection specifically aimed at addressing peripheral pathology is typically in the range of 5-7 ml/sec. This flow rate strikes a balance that ensures adequate contrast material delivery while minimizing the risk of complications, such as reflux or extravasation.

A flow rate in this range allows for efficient opacification of the vessels, which is crucial for accurate imaging and assessment of vascular pathology. The aim is to achieve sufficient contrast filling of the target vessels without overwhelming them, which could lead to issues with visibility or vascular trauma.

Maintaining this flow rate enables the radiologist to achieve optimal imaging results, providing clear and diagnostic-quality images for evaluation. This approach also reflects the standard practices observed in clinical settings, ensuring that the procedure aligns with widely accepted protocols in interventional radiology.
