RESUMO
Objective The aim to assess the methodology and feasibility of ultrasound guided percutaneous thrombin injection(UGTI) for the treatment of Iarogenic Femoral Arterial Complexity Pseudoaneurysms(IFACP).Methods Thirty two iarogenic femoral arterial complexity pseudoaneurysms patients following femoral arerial puncture for arterial angiography were treated with UGTI.Twenty-three IFACP with 2 lobes,8 IFACP with 3 lobes,1 IFACP with 4 lobes.Under local anesthesia the lobe was pene trated by artery needle successively and thrombin jection was performed slowely into distal lobe with US guide precise localization.Dynamical observation was performed for the status of thrombogenesis and cavity plugging.US follow-up examination were performed after 24 h and 7 d.Results Reperfusion occurred in IFACP with 3 lobes after 24 h and UGTI failure.IFACPs with 4 lobes failure.Nothromboembolic,infectious,allergic complication soccurred.Conclusion UGTI is the first mothed for the treatment of IFACP.Precise localization and percutaneous can enhance the ratio of treatment of IFACPs and avoid the severe complications.
