Background: Peripheral arterial disease (PAD) is known as the greatest risk factor affecting the amputation of diabetic foot. Thus, it is crucial to understand the epidemiology of PAD associated with diabetic foot and the relationship between PTA and amputation in predicting prognosis. However, no such multi-year data are available in Korea. Thus, the purpose of this study was to investigate trends of amputation involving diabetic foot based on vascular interventions for PAD in Korea. Methods: This study was conducted using six-year data obtained from Health Insurance Review and Assessment Service from January 1, 2011 to December 31, 2016. Our study included data pertaining to diabetic foot, PAD, and vascular intervention codes (percutaneous transluminal angioplasty [PTA, M6597], percutaneous intravascular installation of stent-graft [PIISG, M6605], and percutaneous intravascular atherectomy [PIA, M6620]). We analyzed the number of vascular interventions and minor and major amputations each year. The relationship between annual amputation and vascular intervention was analyzed using χ2 test. Results: The overall number of vascular interventions increased from 253 (PTA, 111; PIISG, 140; and PIA, 2) in 2011 to 1,230 (PTA, 745; PIISG, 470; and PIA, 15) in 2016. During the same period, the number of minor amputations increased from 2,534 to 3,319 while major amputations decreased from 980 to 956. The proportion of minor amputations among patients who underwent vascular intervention was significantly increased from 19.34% in 2011 to 21.45% in 2016 while the proportion of major amputations among these patients was significantly reduced from 9.88% to 4.27%. In addition, the association between vascular intervention and amputation increased from 0.56 (spearman correlation coefficient) in 2011 to 0.62 in 2016. Conclusion: In diabetic foot patients, increase in vascular intervention resulted in a change in amputation pattern, showing statistically significant correlation.
