Possible Mechanism for Common Femoral Artery Occlusion with the Perclose Suture Device

CFA occlusion by the Perclose device is the result of suture firing into the posterior CFA wall, which requires interposition of the vessel between the footplate and suture needles. The proposed mechanism is anchoring of the footplate in the origin of the branch vessel, which allows for capture of the posterior CFA wall. Technical reasons may include high or low puncture near CFA branches, less than 45° angulation of the device in relation to the CFA, and axial rotation of the device, which may allow for footplate anchoring in the branch vessel origin.
