aortogram
Pronunciation: ay-OR-to-gram
Radiographic imaging study specifically focused on visualizing the aorta and its major branches using contrast material injection.
Full Definition
An aortogram is a specialized form of angiography that provides detailed visualization of the aorta and its major branch vessels. The procedure typically involves catheter placement in the aortic root or arch with subsequent contrast injection to opacify the entire aorta from root to bifurcation. Aortograms are essential for diagnosing aortic aneurysms, dissections, coarctation, and branch vessel stenoses. The study can be performed as part of cardiac catheterization (ascending aortogram) or as a peripheral angiographic procedure (thoracic or abdominal aortogram). Modern techniques include digital subtraction angiography and CT aortography, each offering specific advantages for different clinical scenarios.
Usage
Usage note: Specify anatomical region (thoracic, abdominal) when referring to aortographic studies.
