Percutaneous Closure of Iatrogenic Ascending Aortic Pseudoaneurysms Following Surgical Aortic Repair.

We present a case series of 4 iatrogenic ascending aortic pseudoaneurysms that were all successfully repaired with a percutaneous approach. Pre-procedural imaging, device selection, and procedural techniques are described. With careful preparation and patient selection, catheter closure of iatrogenic ascending aortic pseudoaneurysms can be performed reliably and safely.
