Abstract

Background: The ankle – branchial index (ABI) is simple to performed, so it is recommended to screen and early diagnose the lower extremity artery disease (PAD). Beside the high sensitivity and the high speccificity, rearches in the world  has shown  that ABI have close relationship to the severity of PAD. Subjects and Methods: A Cross-sectional study on 158 lower limbs of 79 patients with lower extremity artery disease. Patients were performed lower lim artery MSCT, took medical history, clinical examined and measured ABI. Then, we finded the relationship of ABI to clinical characteristics and subcliniccal characteristics on MSCT. Results: ABI was significantly lower in the limbs with ≥  2 sick arteries in compare to limbs with one sick artery (p = 0,002), in the limbs with ≥ 2 sick artery floors in compare to limbs with one  sick artery floor (p=0,01). ABI was also significantly lower in the limbs with pain in compare to limbs without pain (p=0,001); and the limbs with symptom of severe anemia in compare to limbs without this symptom (p =0,001). Conclusions: The ankle – branchial index had a significantly corelation to the severity of clinical symptom of the lower extremity artery disease and the level of artery damage on MSCT.
