Ultrasound guided thrombin injection for treatment of iatrogenic femoral pseudoaneurysms / 国际外科学杂志

ABSTRACT

Objective To evaluate the effect and safety of ultrasound-guided pereutaneous thrombin injection for the treatment of iatrogenic femoral arterial pseudoaneurysm.Methods Thirty patients [6 male,24 female,age range 45-82 years,mean (63 ± 10) years] were found to have pseudoaneurysms confirmed by ultrasound between 1 and 7 days following femoral arterial puncture from July 2011 through July 2014.Results All patient had pseudoaneurysm thrombosis after the first procedure.Thrombin 200-1000 U (50 U/mL)was injected into the pseudoaneurysm under ultrasound-guidance,performed.One patient showed acute allergy 5 min after thrombin injection,which was relieved by anti-allergic therapy.No thromboembolic complications or infections occurred.Conclusions Ultrasound-guided pereutaneous thrombin injection is a safe and effective noninvasive method for the treatment of iatrogenic femoral pseudoaneurysm and should be considered as first-line therapy.
