| Objective:the morbidity of the diabetic foot was increased annually and became the main reason of amputation without trauma, and brought heavy burden for sufferer and society. To explore the angiographic characteristic of lower extremities of patients with diabetic foot and evaluate clinic effect of synthetic interventional treatment for diabetic foot.Material and Method:The angiographic results of 35 lower extremities of 23 diabetic patients, the characteristics of respective clinical stages and the stenosis degree at different arterial segments were undergone statistical analysis. PTA with balloon, stent, anticoagulant therapy, or thrombolysis was selected for treatment, and the ABI, skin temperature, the limb distance were compared before and after treatment, and the patency rate and limb-saving rate were calculated.Result:(1) According to the angiography, below-knee arteries were involved more than aboved-knee arteries, and most of them were complicated lesions. Most of the above-knee arteries were slightly or moderately stenosised, but the majority of the below-knee arteries were severely stenosised or were complete occlusion. (2) The re-open rate of stenosis arteries were 85.4%, and the re-open rate of occlusive arteries were 75%. (3) The ABI was elevated significantly after the treatment (0.34±0.04 vs 0.87±0.03, P<0.05). (4) The skin temperature of the limbs were elevated after the treatment (31.23±1.86 vs 35.27±1.54, P<0.05). (5) The limb distance were extended after treatment (100.3±30.2 vs 1326.6±131.3, P<0.05). (6) The cumulative patency rate was 88% at 1 year,65% at 2 year. The secondary arterial patency rate was 96% at 1 year,83% at 2 year, and the limb salvage rate was 100%.Conclusion:there were most likely to have severe stenosis in the below-knee arteries in diabetic foot patient, and synthetic interventional treatment could relieve the symptom and elevated the limb salvage rate, but the long-term effect might need more exploration. |
