What is the minimum volume typically required for injections in small vessels?

In interventional radiology, when considering the injection volumes for small vessels, it is crucial to balance efficacy and safety. The correct range, 6 - 10 milliliters, is often needed to ensure adequate filling of the vascular space without causing undue pressure or damage to the vessel walls.

This volume is generally sufficient to achieve effective contrast distribution for imaging purposes or to deliver therapeutic agents. Smaller volumes, such as those in the lower range, might not provide the necessary dispersion in blood flow or may result in incomplete visualization or treatment of the targeted area.

Furthermore, using a volume that is too high can risk complications such as vessel rupture or extravasation. Thus, the 6 - 10 milliliters range represents a practical standard in clinical practice that ensures sufficient volume while minimizing risks associated with injection in small vessels.
