Abstract:Objective To investigate the effect of early imaging and intervention(choosing the best treatment plan according to the early imaging examination) on reducing amputation rate in patients with diabetic foot ulcer.Methods Eightynine patients with diabetic foot ulcer,who admitted to the department of hand and foot vascular surgery of Huizhou First People′s Hospital from January 2016 to January 2018,were selected as study subjects and were randomly divided into study group(n=45) and control group（n=44）.The early imaging and intervention was performed in study group,and the conventional intervention was performed in control group.The amputation rate,the total effective rate,wound healing and prognosis were compared between two groups.Results The amputation rate in study group was significantly lower than that in control group (2.22% vs 25.00%,χ2=9.895,P=0.002),and the total effective rate was significantly higher than that in control group（97.78% vs 75.00%,χ2=9.895,P=0.002）.Compared with control group,the wound healing rate increased,and the wound healing time significantly decreased in study group (P<0.01).After treatment,the ankle brachial index(ABI) was statistically higher than that before treatment in two groups and was higher in study group than that in control group (P<0.05,P<0.01).The ulcer recurrence rate in study group was significantly lower than that in control group（2.22% vs 18.18%,χ2=4.602,P=0.032）.There were no deaths in both groups.Conclusion Early imaging and intervention is beneficial to reduce amputation rate,improve treatment effect and prognosis for the patients with diabetic foot ulcer.
