Background:Doppler ultrasound is a non-invasive, inexpensive tool that complements the role of computed tomography, magnetic resonance imaging, and catheter digital angiography in the diagnosis, and monitoring of vascular disease.
Objectives:The main purpose of this study was to evaluate the lower limb arterial system in diabetic foot patients and to analyze the role of color Doppler in the diagnosis of diabetic arteriopathy.
Patients and methods: This is a case-control study conducted at Qena University Hospital, South  Valley University, Qena. Group I: 40 healthy people were included in the control group. Group II: 40 patients known to be diabetic in the duration between August 2019 to August 2020.
Results: There was no significant difference between the two groups regarding the flow lumen diameter of the right / left dorsalispedis artery and the right / left posterior tibialartery. There was a significant difference between the two groups regarding the vessel wall thickness of the right / left dorsalispedis artery and right / left posterior tibial artery. The majority of patients had biphasic flow patterns in both the dorsalispedis artery and posterior tibial artery, and blood flow parameters (PSV, PI, RI) for PDA and PTA were found to be significantly higher in the diabetic group and the EDV was found significantly lower in the diabetic group.
Conclusion: Doppler ultrasound has a high diagnostic yield in depicting abnormalities in patients with clinical features of peripheral arterial disease.
