Aims to study the clinical application and the effect of interventional radiotherapy in the treatment of early vascular lesions of type II diabetic foot, and compare the postoperative outcome.

A total of 58 patients with type II diabetic foot were admitted into and treated in our hospital, who were randomly divided into two groups, i.e. intervention group (n=29) and control group (n=29), to receive interventional therapy or contrast treatment, respectively. The outcome of post-treatment from both groups was compared.

The intervention group acquired a total effective rate of 89.66%, which is significantly higher than that in the control group (58.62%), and the difference was statistically significant (x²=4.542, P=0.002). The ulcer healing time of the intervention group was shorter than the controls (d: 47.9 ± 11.5 vs. 93.3 ±7.2, t = 4.653, P < 0.05), and the length of hospital stay for the intervention group was also less than that of the control group (d: 21.8 ± 3.4 vs. 37.6±4.3, t = 5.742, P < 0.05). However, both groups had their clinical symptoms improved, still with the intervention group gaining better scores, which showed statistical significance (P < 0.05). The follow-up study of 6 months after the interventional therapy showed that severe numbness, pain, and the low temperature in patients were much improved, and ABI index was higher than the preoperative. As such, the differences were statistically significant (P < 0.05).

Interventional radiotherapy can effectively improve the clinical symptoms of type 2 diabetic foot patients with peripheral vascular lesions.
