Abstract


Aims: To study the effectiveness of Doppler ultrasonography in diagnosing peripheral vascular disease in diabetic foot
patients when compared to clinical palpation of pulse.
Materials and method: The study was carried out in 115 diabetic patients. Peripheral pulses like posterior tibial and
dorsalis paedis artery were checked. The presence of vasculopathy was checked with Doppler scanning of Dorsalis
pedis artery and Posterior tibial artery. Qualitative waveform analysis was performed by visual interpretation of
continuously displayed waveforms. Thus we observe the presence of degree of stenosis in the lower limb arteries with
the help of pulse waveform ultrasonography and results were calculated by statistical method.
Results: In the present study, it was found that in affected right lower limb patients of diabetic foot, by clinical method of
palpating the peripheral pulses no pulse was felt (positive finding) in 15 patients and weakly palpable or strongly
palpable pulse (negative finding) were felt in 51 patients. Also by doing Doppler study for the same group of patients,
stenosis was found (positive finding) in 59 patients and no stenosis (negative finding) was found in 7 patients. By using
chi square test the p value found to be <0.00001 which was statistically significant. In affected left lower limb patients of
diabetic foot, by clinical method of palpating the peripheral pulses no pulse was felt (positive finding) in 9 patients and
weakly palpable or strongly palpable pulse (negative finding) were felt in 40 patients. Also by doing Doppler study for
the same group of patients, stenosis was found (positive finding) in 41 patients and no stenosis (negative finding) was
found in 8 patients. By using chi square test the p value found to be <0.00001 which was statistically significant.
Conclusion: Doppler ultrasonography of lower extremities had a greater accuracy in diagnosing peripheral vascular
disease of diabetic foot patients when compared to clinical palpation of pulses.
