Abstract
Abstract Introduction Iatrogenic, postcatheterization pseudoaneurysms (PSA) of the femoral artery are a common complication after diagnostic and interventional procedures, with up to 7.7% incidence. Treatment includes surgical repair, ultrasound-guided compression (USGC) repair of the tract of the PSA, or recently ultrasound-guided thrombin injection (UGTI). Large (>1.8 cm) PSA sac with short (<3 mm) and/or wide (>3 mm) tract has higher complication ratio such as thromboembolic events after UGTI. Those cases are considered for protective balloon inflation during thrombin injection. The aim of our study was to evaluate the success rate of preventing escape of the thrombin during UGTI with simultaneous manual compression on ipsilateral iliac artery. Methods and results We reported 46 patients, 17 males and 29 females, aged 53–74 years, with iatrogenic, postcatheterization femoral artery PSA. Out of 46 patients, 7 were successfully treated with USGC. The rest of the patients were treated with UGTI with simultaneous manual compression on ipsilateral iliac artery to stop the flow in PSA, and to avoid thrombin escape into the native circulation. Success rate of UGTI with manual compression of ipsilateral iliac artery was 97% with the complication rate of 2.6%. Conclusion Our study confirms that UGTI treatment of the PSA of the femoral artery combined with compression of the ipsilateral iliac artery could be a safe and reliable method of the thrombin escape prevention into the systemic circulation, as good as more invasive and demanding methods.

Summary
Iatrogenic, postcatheterization pseudoaneurysms (PSA) of the femoral artery are a common complication after diagnostic and interventional procedures, with up to 7.7% incidence. Large ([1.8 cm) PSA sac with short (\3 mm) and/or wide ([3 mm) tract has higher complication ratio such as thromboembolic events after UGTI Those cases are considered for protective balloon inflation during thrombin injection. It is well described that patients with large ([1.8 cm) PSA sac, with short (\3 mm) and/or wide ([3 mm) tract have higher complications ratio such as thromboembolic events after thrombin injection. Those patients are considered for UGTI with protective balloon inflation during thrombin injection which is technically and resourcefully more demanding. The aim of this study was to evaluate success rate of preventing escape of the thrombin during UGTI with simultaneous manual compression on ipsilateral iliac artery
