Associations Between Systolic Pressure, Vascular Waveform, and Volume Flow with Debridement or Amputation Treatment Decisions in Diabetic Foot Ulcer Patients.

Introduction: Diabetic foot ulcer disease, affecting 6.3% of the global population, necessitates crucial decisions regarding debridement and amputation, with substantial cost, morbidity, and mortality implications. This study's primary goal is to determine effective vascular examination modalities, including systolic blood pressure, vascular waveforms, and blood volume flow to guide optimal treatments for diabetic foot patients.

Method: This cross-sectional study at Cipto Mangunkusumo General Hospital aimed to identify effective vascular examination modalities, such as systolic blood pressure, vascular waveforms, and blood volume flow, to guide treatment choices for diabetic foot patients. The study included 38 subjects, equally split between debridement and amputation groups.

Results: Notably, the presence of a biphasic pattern in popliteal artery vascular examinations was associated with the decision for amputation in diabetic foot patients (p < 0.05). The Chi-square test revealed that a biphasic ultrasound pattern served as a predictive factor for amputation among diabetic foot patients, with three times more biphasic patients choosing amputation over debridement. Conversely, assessments of popliteal artery systolic pressure, common femoral artery waveform, popliteal artery volume flow, and common femoral artery volume flow showed no significant correlations with the choice of debridement or amputation treatment for diabetic foot patients.

Conclusion: In summary, ultrasound assessment of vascular waveform in the popliteal artery emerges as a predictive factor for amputation or debridement in diabetic foot patients.
