flush aortogram
Angiographic technique using high-volume contrast injection in the aorta to visualize multiple vessel origins simultaneously.
Full Definition
A flush aortogram is a specialized angiographic procedure where a large volume of contrast material is rapidly injected through a catheter positioned in the aorta, typically at the level of the renal arteries. This technique allows simultaneous visualization of multiple arterial branches arising from the aorta, including renal, mesenteric, and other visceral arteries. Flush aortograms are particularly useful for screening multiple vessels efficiently, detecting arterial stenoses, and providing an overall assessment of aortic anatomy. The procedure requires careful positioning and timing to achieve optimal opacification of all target vessels while minimizing patient exposure to contrast and radiation.
Usage
Usage note: Distinguish from selective angiography which targets individual vessels.
