Introduction: Arterial pseudoaneurysms are well known iatrogenic complication of percutaneous angiographic or interventional vascular procedures. In the past, the definitive treatment option was open surgical repair which is a relatively invasive procedure. In the last few years, Ultrasound (US) guided percutaneous thrombin injection has been gaining popularity as definitive treatment of pseudoaneurysms.
Aim: To evaluate efficacy and safety of US guided percutaneous injection of thrombin for treatment of iatrogenic femoral pseudoanurysms at a tertiary care interventional radiological and cardiology centre.
Materials and Methods: A retrospective analysis was conducted on 38 consecutive patients, diagnosed to have iatrogenic femoral artery pseudoaneurysms by Doppler study, in the period from Jan 2013 to Jun 2016. All these patients were treated by US guided percutaneous injection of thrombin solution inside the pseudoaneurysm sac till contents became echogenic and flow inside the pseudoaneurysm stopped completely. One month further follow up in all these patients was done.
Results: The dose of thrombin injected varied from 200-1000 IU (mean 300 IU). Immediate thrombosis was seen in all the pseusdoaneurysms. Follow up at 24-48 hours showed complete thrombosis and regression of pseudoaneurysm in all the patients except one in whom a small residual sac was seen which thrombosed completely on second thrombin injection. Further follow up at one month showed regression of aneurysms in all the cases. No significant post procedural clinically significant complications were seen in any of the patients.
Conclusion: US guided percutaneous thrombin injection is a highly successful and safe procedure for the treatment of iatrogenic femoral pseudoaneurysms.
