a 71 year old male presents with post-op evaluation of his rt femoral-posterior tibial artery reverse saphenous vein bypass graft: at rest the ABI is 0.92. the biphasic Doppler velocities are 85 cm/sec in the native CFA, 100 cm/sec in the prox anastamosis, and 50 cm/s at knee level, and 48-50 cm/s at the distal anastomosis and native PTA.
