New surgical techniques in peripheral vascular diseases * have revived interest in arteriography. One of the basic problems is to visualize the aorta and the femoral artery in their entirety and in one procedure, in order to obtain information about their anatomical and functional state on several films.
Evidence of intimal narrowing or obstruction obtained in the usual procedure by using a single film does not permit a positive differential diagnosis between an organic and a spastic lesion. Multiple films taken in rapid succession are essential for proper diagnosis. For this purpose a special apparatus with rapid change-over of cassettes has been described.3 However, such special apparatus is not readily adaptable to existing equipment and space.
Injection of radiopaque medium into the aorta, properly timed, will visualize the femoral arteries and eliminates the need of an additional open or percutaneous injection into the femoral artery. Satisfactory aortograms and femoral arteriograms
