• We developed a model that simulates distal arterial occlusive disease to determine the effects of sympathectomy on certain hemodynamic changes. Two groups of seven dogs each received unilateral distal popliteal artery ligation. intraarterial BPs, angiography, pulse volume recordings (PVRs), and photoplethysmograms were taken of the distal hind limb throughout the experiment. After ligation, PVR and distal hind limb pressures were lowered to less than half of the preligation values. Four days after unilateral distal popliteal artery ligation, group 2 dogs received lumbar sympathectomy on the same side as the ligation. One week after sympathectomy, the PVR amplitudes and pressures showed a transient significant rise. Two weeks after sympathectomy, the PVR pressures and amplitudes returned to the previous, diminished postligation values.
