Segmental obliterative disease of the terminal aorta and iliac arteries has recently received increasing attention. A great number of reports * have shown that its underlying pathologic process is atherosclerosis leading progressively to thrombus formation, that the lesions may begin at the bifurcation or most frequently in one or both common iliac arteries (Fig. 1), and that the development of these lesions is slow, insidious, and Progressive.
From the clinicopathologic standpoint it may be emphasized that this syndrome may go through two distinct phases: stenotic and occlusive. Recent experience † with aortic resection and graft replacement in the treatment of the aortoiliac syndrome appears to indicate that when surgery is performed at an early stage the results are much more gratifying. Therefore, detection of this arterial disease at its stenotic stage may prove of practical value.
In a previous experimental work on stenosing arterial thrombosis,10 it was shown that while
