Abstract

PURPOSE
The purpose of this study is to establish guidelines for ankle-brachial index (ABI), toe-brachial index (TBI) and toe pressure with regard to healing of diabetic foot amputation wound. MATERIAL AND METHODS: We designed a retrospective study that included patients with diabetic foot ulcer. From 2008 to 2011, 46 patients who had suffered from amputation of a foot due to diabetic foot ulcer were included in this study. We divided them into amputation-success group and amputation-revision group, and compared their ankle-brachial index (ABI), toe-brachial index (TBI) and toe pressure between two groups. Amputation-revision group is that first forefoot amputation is failed to heal successfully and need to have another proximal amputation.
RESULTS
Toe pressure was 78 mmHg (54~107) in the amputation success group, 0 mmHg (0~43) in the amputation revision group (p=0.000). Ankle-brachial index was 1.1650(1.0475~1.1975) in the amputation success group, 0.92(0.5275~1.0750) in the amputation revision group (p=0.05), and toe-brachial index was 0.6100(0.4050~0.7575) in the amputation success group, 0.00(0.00~0.4150) in the amputation revision group (p=0.04), respectively.
CONCLUSION
ABI, TBI, toe pressure of amputation success group were significantly higher than those of amputation revision group.
