[Collateral compensation of blood flow and hemodynamics of the lower extremities in atherosclerotic occlusion of abdominal aorta].
Results of investigation of collateral blood flow in 159 patients with atherosclerotic occlusion of abdominal aorta of various kinds were presented. There was shown, that a. mesenterica superior constitutes the main visceral branch, securing the blood circulation compensation in total, high and middle occlusion of abdominal aorta and in low occlusion--a. mesenterica inferior. The change of direction and enhancement of blood flow along a. epigastric inferior was noted in all the patients. In spite of identity of total volumetric blood flow along the collateral branches, the volumetric blood flow velocity along the lower extremities arteries is determined by the level and spread of aortal occlusion.
