2. Fig. 1
Angiogram of middle third of a composite cephalic/basilic/ saphenous reversed vein bypass from the common femoral artery to the peroneal artery. The area of stenosis (arrow) was detected initially on duplex scan 4 months after operation (the PSV within the stenosis was 447 cm/sec compared with 79 cm/sec in adjacent segments). An interposition vein graft corrected the velocity abnormality.

3. Fig. 2
Angiogram shows the distal anastomosis of a composite saphenous/cephalic reversed vein profunda femoris to posterior tibial artery bypass. Duplex scan had demonstrated markedly increased distal graft PSVs after 16 months (>520 cm/sec, compared with 56 cm/sec and 73 cm/sec in the adjacent vein segments). The lesion was treated with an interposition vein graft (see Table II).
