6f multipurpose catheter

A 6-French (6-F) access was obtained in the femoral artery and vein separately. The right atrium systolic pressure was recorded with a 6-F multipurpose catheter (Medtronic, Minneapolis, USA). Under the guidance of a 5F JR 4.0 or Cobra catheter (Medtronic, Minneapolis, USA), the arteriovenous loop was established with a 260 cm, 0.035 inch, hydrophilic guide wire (Terumo, Tokyo, Japan) by crossing both the leak and the Cabrol’s shunt and subsequently advancing into the right atrium and then snaring and exteriorizing from the femoral vein. Then the delivery sheath (6- to 8-F according to the device size) crossed the leak in retrograde approach. The occlusion device with appropriate size determined by AAL size and shape, was introduced alongside the loop, and carefully deployed across the leak. When the technical success was obtained, the loop guide wire could be was removed and the occluder was finally released (Figure 2A,B).
