AIM: The aim of this study was to assess the diagnostic accuracy of the Doppler derived maximal systolic acceleration (ACCmax) as a novel technique for evaluating peripheral arterial occlusive disease (PAOD) in patients with diabetes mellitus, who are known for a falsely elevated ankle-brachial index (ABI).
METHODS: In this retrospective analysis ACCmax was measured at ankle level in a series of 163 consecutive patients referred to the vascular laboratory for initial assessment of PAOD. Patients were classified according to the presence or absence of diabetes. In the non-diabetic patients PAOD was defined as ABI ≤0.90. This group was used to establish the association between ACCmax and ABI in a linear regression model. The result was then used to predict the presence or absence of PAOD in the diabetic patients.
RESULTS: The authors examined 301 lower limbs. The study group consisted of 166 limbs of patients without diabetes and 135 limbs of patients with diabetes. PAOD was present in 52% of limbs in the nondiabetic group versus 59% of limbs in the diabetic group (ABI ≤0.90, or in case of non-compliant vessels toe-brachial index (TBI) ≤0.70). An ACCmax cut-off value of >10 m/s2 was found to be highly predictive for the exclusion of PAOD (negative predictive value 95%). In addition, the ACCmax cut-off value of <6.5 m/s2 was highly predictive for the detection of PAOD (positive predictive value 99%). A strong quadratic association was found between ACCmax and ABI in the non-diabetic group (R2=0.85). In the diabetic patients R2 values were 0.81 and 0.79 after ABI and TBI measurement respectively.
CONCLUSION: DUS-derived ACCmax is an accurate marker that could offer significant benefits for the diagnosis of PAOD, especially in diabetic patients.
