Background: Peripheral vascular disease is assessed by history of intermittent claudication pain of lower limbs. Colour Doppler study is a noninvasive technique which does not require any patient preparation or contrast study. It directly detects the stenotic segment by their waveform pattern. In this study we correlate ankle brachial pressure index with intima wall thickness using colour Doppler. Methods: Around 60 patients were selected for the study. The selected patients were evaluated for detailed clinical history, ankle brachial pressure index (ABPI) using colour doppler was then correlated with carotid intima wall thickness. The ABPI ratio was estimated in every patient by dividing the mean systolic blood pressure of brachial artery by systolic blood pressure of dorsalis pedis artery followed by Colour duplex ultrasound study. Results: According to our study There is a weak positive correlation between Ankle Brachial Index and Mean Internal carotid Artery Wall Thickness (R2=0.041) and this association was not found to be statistically significant. (p value = 0.120) Conclusion: According to our study, the ABI is an efficacious study to factor out PAD. An abnormal ABI can predict the duration and severity of the arterial disease with results similar to that of arterial Doppler. However, more studies are necessary for further confirmation and to establish the prognostic value of the ABI.
