Much of our knowledge of collateral circulation has been derived from anatomical studies which have been subjected to pathophysiological interpretation. Arteriography provides a dynamic method of investigating the in vivo collateral patterns in extremities. This report concerns such a study of collateral arterial circulation in the lower extremities as obtained from 100 full leg-length arteriograms9,10 augmented by serial arteriograms taken of the iliac and pelvic arteries visualized by contralateral femoral arterial injection of a radiopaque medium. Available for study were acute and chronic occlusive lesions at various sites in the leg due to arteriosclerosis, trauma, and arteriovenous fistulae.
General Considerations of Collateral Circulation
Nature has provided more ample alternate venous and lymphatic routes than she has arranged for arterial collaterals. However, the inherent ability of the arterial system to adjust to various types of arterial lesions and the application of sound principles of hemodynamics to the functioning of
