flush aortogram
Angiographic technique using high-volume contrast injection to visualize entire aorta and major branches.
Full Definition
An angiographic imaging technique that involves rapid, high-volume injection of contrast material through a pigtail or similar catheter positioned in the aorta to simultaneously opacify the aortic lumen and its major branch vessels. This technique provides comprehensive evaluation of aortic anatomy, branch vessel origins, and overall vascular architecture in a single acquisition. Flush aortograms are commonly performed to assess aortic aneurysms, dissections, branch vessel stenoses, and to plan complex interventional procedures. The injection parameters must be carefully adjusted based on cardiac output and vessel size.
Usage
Usage note: Distinguish from selective angiography in procedural descriptions.
