Leriche syndrome is used to describe chronic lower limb ischaemia characterised by:
- intermittent claudication in the buttocks
- pale, cold legs
- sexual impotence
- absent femoral pulses
It is caused by aorto-iliac obstruction (e.g. saddle embolism at bifurcation of the aorta). The vessels above and below may be relatively normal.
