ABSTRACT
1. On two dogs microangiographic studies were performed on the nutrient vessels of the abdominal aortic wall enclosed for 12 months by an unyielding polyethylene tube. 2. In the aortic portions above and below the enclosed part, a normal vascular pattern of the vara vasorum was demonstrated. 3. Immediately above and below the position of the tube, newly formed abnormal vessels were seen directed towards the enclosed aortic segment. 4. These abundant vascular networks were seen to meet in the enclosed portion of the wall. 5. The vascularization was distributed in all layers of the aortic wall except in the intima, which was free from vessels. 6. The tunica media was split up and completely distorted, the abnormal vessels prenetrating it throughout. 7. The nature of this newly formed circulation was discussed. It was considered plausible that the normal nutrient circulation of the wall was ruined by the systolic compression of the wall against the rigid tube. The anoxic tissues stimulated vascular ingrowth. 8. The findings were discussed with special reference to the etiology of the sclerotic degeneration of the femoral artery in the Hunterian canal.

The condition is thought to result from embryonic overfusion of the two dorsal aortas. The diagnosis may be considered in patients presenting with hypertension...
