BACKGROUND: Our objective was to determine the prevalence of aorto-iliac disease, total inflow disease, superficial femoral disease and infra-popliteal disease in patients presenting for peripheral arterial disease testing and who were found to have an abnormal ABI.
METHODS: PADfile the peripheral arterial disease module of CARDIOfile was searched for all patients with an abnormal ABI (<0.95) in one or both lower limbs. There were 1456 studies of which 348 (23.9%) were abnormal. All studies were performed using the 4-cuff method. Aorto-iliac disease was defined when both upper thigh systolic pressures were 20mmHg lower than the corresponding lower thigh systolic pressure. Infra-popliteal disease could also be unilateral or bilateral.
RESULTS: See Table 1.
CONCLUSION: In patients with an abnormal ABI, 72.4% have aorto-iliac disease and 91.8% have aorto-iliac or ileo-femoral disease. 57.5% have infra-popliteal disease and 44% have superficial femoral disease.
