We performed 300 femoral arteriographies using a long cassette holding a 25 x 90 cm. differential screen for the whole-limb arteriography.
The differential screen proved practical for use in the arteriographic examination of the lower limb. Forty centimeters of highly concentrated contrast medium was injected

into the femoral artery in the retrograde direction during a period of 20 seconds. Roentgen exposure was made immediately before the end of the injection. There were

no complications associated with these arteriographies.
A series of 106 cases of occlusive arterial disease in the lower limb, proved by arteriography,

is analyzed. The series consists of 65 cases of thromboangiitis obliterans (TAO), 26 of arteriosclerosis obliterans (ASO), 5 of embolism and 10 of unclassified type.
It is the author's belief that TAO in the early stage and ASO can be distinguished from each other based on purely arteriographic findings.
