| dc.description.abstract | Introduction The effectiveness of hyperbaric oxygen therapy (HBOT) on selected diabetic foot wounds continues to be controversial. A holistic approach to diabetes and its comorbidities may be beneficial in the discussion of the proper application of this treatment modality. The aim of the current study is to evaluate the efficacy of HBOT on diabetic foot wounds and provide clinical data that may support this knowledge. Methods The present study was a retrospective analysis of the effect of HBOT on diabetic foot lesions ranging 3–5 on the Wagner Grading System. Patients had been treated with HBOT and monitored for 12 months. The results were analyzed in relation to age, gender, diabetes duration and type, microangiopathic complications, peripheral arterial disease (PAD), history of coronary artery disease, stroke, hypertension, smoking habits, glycated hemoglobin, blood sedimentation rate, C-reactive protein, and number of HBOT sessions. Microangiopathies were evaluated as retinopathy, nephropathy, and neuropathy. PAD was determined by available color Doppler ultrasonography and/or angiographic data depending on a modified scoring system. The data of arteries from the aorta to the dorsal pedal artery were scored singly. Average scores of aorto-iliac, femoral, popliteal and pedal levels were also evaluated with this system to compare the healing results in relation to PAD. Results One hundred and seventeen patients with 126 diabetic foot wounds were treated. Histories of coronary artery disease, stroke, and non-proliferative or proliferative retinopathy had negative effects on HBOT (P = 0.002, P = 0.015, P = 0.022, respectively). Depending on the scorings of PAD, the single arterial scores and average scores of aorto-iliac, popliteal and pedal levels had no relation to outcomes, while the average scores of the femoral arterial level affected the results (P = 0.048). Conclusions Diabetic foot patients with histories of coronary artery diseases or stroke and non-proliferative or proliferative retinopathy might resist HBOT. PAD at the femoral arterial level has been shown to have a significant negative effect on HBOT outcomes that should be first considered for surgery. In contrast, PAD below the knee does not seem to be an obstacle to the efficacy of HBOT.
