Area reduction of perforation with a small-size sheath technique for iatrogenic femoral artery pseudoaneurysm with a large perforation

Open surgery for femoral artery pseudoaneurysms is invasive, and complications can be detrimental. Several cases of treatment of iatrogenic femoral artery pseudoaneurysms using percutaneous suture-mediated closure devices have been reported. However, it is difficult to properly deploy the foot of the device to the arterial wall when the perforation area is large. We developed a technique using a double guidewire to partially occupy the perforation with a small-size sheath, which reduces the area of the perforation. This AREPAS (area reduction of perforation with a small-sized sheath) technique might allow for minimally invasive closure of perforations even in patients with large perforation areas.
