RESUMO
AIMS: Iatrogenic pseudoaneurysms of the femoral artery lead to increased morbidity and mortality, especially when surgical treatment is necessary. Manual compression and thrombin injection are commonly used to occlude the pseudoaneurysms. However, in some cases these treatment options are inapplicable or unsuccessful. The aim of the present study was to examine the feasibility, effectiveness and safety of a novel approach with the use of suture-based closure devices to treat pseudoaneurysms. METHODS AND RESULTS: Between January 2014 and May 2016, a total of eight iatrogenic pseudoaneurysms of the femoral artery were treated by the interventional closure technique after at least one ineffective attempt at manual compression. After puncture of the cavity, a PTCA guidewire was used to pass the neck of the pseudoaneurysm and a sheath was inserted in the femoral artery. Afterwards, a suture-based closure system (ProGlide) was used to occlude the neck. All eight pseudoaneurysms were successfully obliterated. No complications occurred during the procedure. CONCLUSIONS: The new interventional technique presented in this study fills the gap in successfully treating pseudoaneurysms that cannot be obturated with conventional techniques. By implementing this new technique in clinical practice, a significant number of open surgical repairs could be prevented.
