Metabolic evaluation of the leg blood flow in claudicating patients with arterial obstructions at different levels.

摘要: Data on the peripheral oxygen utilization and lactate release during standardized leg exercise in patients with intermittent claudication were correlated to level of main arterial obstruction as determined by arteriography corresponding data normals. At comparable loads femoral venous saturation was found be higher more distal obstruction. The calculated blood flow exercising lower proximal obstructions than those obstructions. absence a difference ability sustain graded ascribed differences distribution available flow. net from seemed total mass ischemic muscle significantly normal all patient groups irrespective level.
