Application Of Lower Extremity Arterial Intervention Combined With Negative Pressure Wound Therapy In The Treatment Of Diabetic Foot

Objective:To investigate the significance of lower extremity arterial intervention in revascularization of lower limb stenosis or occlusion in diabetic foot patients,to observe the clinical effect of lower extremity arterial intervention combined with negative pressure wound therapy in the treatment of diabetic foot.Methods:Collecting forty-six patients who are diabetic foot with lower extremity arterial stenosis or occlusion from July 2016 to February 2019.All patients were randomly divided into observation group and control group.Among the 23 patients in the control group,10 were male and 13 were female,aged 44～69(56.5 ± 12.5)years old.Among the 23 patients in the observation group,12 were male and 11 were female cases,aged 43～66(54.5±11.5)years old.Both groups of patients underwent arteriovenous color Doppler ultrasonography in the lower extremity before stenosis or occlusion.After the the patients were admitted to the hospital,the relevant examinations were completed to exclude patients with severe cardiopulmonary disease and intolerance.The foot was measured by transcutaneous oxygen pressure(TcPO2).According to TcPO2 results,surgical debridement plus VAC vacuum closed drainage or amputation was performed.Anti-infection and micro-circulation treatment were performed after operation.The observation group improved the relevant examination after admission.The lower extremity arterial intervention was performed.The transcutaneous oxygen pressure(TcPO2)was monitored before and after the operation.The lower extremity arterial blood supply was reconstructed for 2 weeks.Negative pressure closed drainage or amputation,anti-infection after surgery,improve microcirculation treatment.Results:transcutaneous oxygen pressure(TcPO2)changes were observed in the observation group after interventional treatment of lower extremity arteries,and statistical analysis showed that there was significant improvement compared with before and after,and the difference was statistically significant(P<0.05).In the control group,the amputation rate was 73.9%and the observation group had an amputation rate of 30.4%.The results showed that the amputation rate of the two groups was significantly different,and the difference was statistically significant(P<0.05).Conclusion:Diabetic foot with lower extremity arterial stenosis or occlusion of the lower extremity arterial intervention for the reconstruction of blood supply,improve the foot microcirculation is significant;diabetic foot patients with lower extremity arterial intervention combined with negative pressure wound therapy technology for diabetic foot healing effect is significant,and it can effectively reduce the rate of amputation under the knee.
