Observation of ultrasound-guided thrombin injection in the treatment of 30 patients with femoral artery pseudo-aneurysm

Abstract

Objective To study the clinical applicated value of thrombin injection in the treatment of 30 patients with femoral artery pseudo-aneurysm guided by color Doppler ultrasound. Methods 60 patients with femoral artery pseudoaneurysm were selected as the observation group, according to a random number table, they were divided into A group and B group, A group was treated with ultrasound guided compression therapy, B group was treated with ultrasound guided thrombin injection;also early femoral artery pseudoaneurysm OK conventional surgical methods for the treatment of 30 patients in the control group. The statistical method of uhrasound-guided two treatment success rate,thrombus formation time and observation group and control group success rate and complication rate. Results Ultrasound-guided compression therapy for 30 cases, 14 cases of successful initial oppression, oppression success rate of 46.6% for the first time,repeat oppression the success rate of 87.5%. Two cases were cured after thrombin injection therapy. B group was treated with thrombin injection of endovascular,24 cases in 30 cases were cured after first injection, the first injection success rate of 80.0% ;all cases were cured after two injections. Thrombus formation time was （0.30 ± 0.05 ）min. treatment success rates for the first time and thrombus formation time were significantly different（ all P 〈 0.01 ）. 30 cases were cured by surgical treatment. Postoperative complication rate was 6.7%. The first treatment success rates and complication rates of the two groups were significantly different（ P 〈 0.05 ）. The total success rates of the observation group and the control group were 100% respectively. The difference was not statistically significant（ P 〉 0.05 ）. Compared with the observation group, the incidence rate of postoperative complications of con- trol group was 6.7% （P 〉 0.05）. Conclusion In the femoral artery pseudoaneurysm positioning and puncture therapy, Color Doppler ultrasound-guided thrombin may provide a reliable basis, thrombosis treatment success rate and thrombus formation time were significantly better than that of ultrasound-guided compression therapy ,which has broad application prospects.
