Abstract:

Objective To analyze the clinical efficacy of interventional therapy in lower limb thrombo angitis obliterans. Method 100 patients of lower limb thrombo angitis obliterans were treated in the Vascular Surgery of Liaocheng People's Hospital from Jan 2019 to Jun 2021 were selected as the study subjects, they were divided into treatment group (n=50) and control group (n=50)by different treatment methods. Conservative treatment was applied for patients in the control group while interventional treatment was applied for patients in treatment group, clinical efficacy was compared between the two groups. Result After treatment, the blood flow velocity of external iliac artery, ankle brachial index, percutaneous oxygen partial pressure and the diameter of dorsalis pedis artery in the treatment group were significantly improved compared with those before treatment (P ＜ 0.05), and were better than those in the control group. However, in the control group, only blood flow velocity of external iliac artery and ankle brachial index were improved after treatment (P ＜ 0.05), and there was no significant difference in percutaneous oxygen partial pressure and dorsalis pedis artery diameter (P ＞ 0.05). The total effective rate of the treatment group was significantly higher than that of the control group (P ＜ 0.05). Conclusion In the clinical treatment of thrombo angitis obliterans, interventional treatment can significantly improve the patient's condition, improve the efficiency of clinical treatment.
