INTRODUCTION:
Diabetic foot ulcer(DFU) is very common yet challenging complication of diabetes worldwide. These ulcers are biologically compromised majorly by ischemia and neuropathy. Ischemia has gained recognition as a significant cause of DFU.
The association of peripheral arterial disease(PAD) largely impacts the treatment outcomes of DFU in terms of ulcer healing, lower limb amputations and mortality. The burden of PAD in DFU in South Indian population has not been assessed adequately in the recent years. A multidisciplinary approach to DFU and prompt diagnosis of ischemia will decrease the loss of limb and life.
OBJECTIVE:
The objective of the study was to assess the peripheral arterial disease and associated risk factors in patients with diabetic foot ulcer.
METHODS:
A total of 100 patients were evaluated in this study. The patients were subjected to detailed history and clinical examination which included distal pulse assessment, ankle-brachial index(ABI) and duplex scan to evaluate PAD. The data was subjected to statistical analysis to find out association between parameters of interest.
RESULTS:
The prevalence of PAD in DFU was found to be 36%. It was more prevalent in males and in age>40 years and higher with increasing age. PAD was associated almost equally with plantar and dorsal ulcers, more often whole of foot was involved. There is significant association of PAD with longer diabetic duration(p
