flush aortography
Non-selective contrast injection technique providing overview imaging of the aorta and major branches.
Full Definition
Flush aortography is a non-selective angiographic technique where contrast material is rapidly injected into the aorta through a pigtail catheter to opacify the entire aortic lumen and major branch vessels simultaneously. This method provides a comprehensive overview of aortic anatomy and is typically the initial step in diagnostic angiography. Flush aortography is particularly useful for identifying the origins of major vessels, detecting aortic pathology, and planning selective catheterization. The technique requires careful attention to injection rates and volumes to achieve adequate opacification while minimizing patient discomfort and contrast load.
Usage
Usage note: Distinguish from selective angiography which targets specific vessel origins.
