The value of the routine lateral aortogram obtained during the contrast material injection for the frontal angiogram is stressed. This application of the basic radiographic principle of recording structures or events in more than one plane has resulted in the following:

1. Detection of completely unsuspected visceral artery stenosis or occlusion. This has been of value in determining the cause of symptoms under investigation or in documenting the potential cause of subsequent disease.

2. Determination of the extent of visceral artery stenosis where its presence is already suspected.

3. Recognition of visceral artery stenosis and occlusion in the frontal aortogram. This is derived from a more complete understanding of the contrast flow pattern and the recognition of post-stenotic dilatation.

4. More complete evaluation of aortic aneurysms as to size, extent of thrombosis, associated stenotic or occlusive visceral artery changes and relationship to the visceral arteries.

5. Recognition of potentially hazardous visceral artery stenosis where selective catheterization should be avoided.
