<![CDATA[Highlights: Biphasic and monophasic waves were abundant in the pedis. Incompressible veins with signs of thrombus are common in the superficial femoral veins. Doppler ultrasound can show vascular abnormalities through various parameters and can properly visualize the vascular condition of the diabetic foot. Abstract Introduction: Diabetes mellitus (DM) frequently causes lower extremity complications due to vascular abnormalities that contribute to diabetic foot disorders. Early vascular assessment is crucial for effective management. This study described the use of Doppler ultrasound (DUS) for evaluating vascular conditions in the feet of patients with DM. Methods: A cross-sectional descriptive study was conducted using secondary data from 58 patients with diabetes (n=58) at Universitas Airlangga Hospital, Surabaya, Indonesia. Data were analyzed using International Business Machines Corporation (IBM) Statistical Package for the Social Sciences (SPSS) version 26.0. This study also described DUS findings, focusing on plaque morphological abnormalities, degrees of arterial stenosis, arterial spectral waveforms, and venous compressibility. Results: Fibrous plaques were most frequently found, predominantly in the popliteal and femoral arteries. Mild stenosis occurred mainly in the femoral arteries, while severe stenosis was more common in distal arteries, particularly the dorsalis pedis. Triphasic waveforms were mostly observed in the femoral area, whereas biphasic and monophasic patterns predominated distally. Incompressible veins with thrombus were frequently identified in the superficial femoral vein. Conclusion: Doppler ultrasound is a valuable tool for assessing vascular conditions in patients with diabetic foot. The findings highlight the distribution of stenosis severity and waveform changes, which become more prominent in the distal region.]]>
