Table 5.
Cases of Device Embolization
| Case # | Age | PDA Type | PDA Size | Initial Device(s) | Fate | Final Device |
|---|---|---|---|---|---|---|
| 1 | 3 mo | C | 3.5 to 4.3 | ADO 6/4 | Emb to LPA/snared | AVP II 4 mm |
| 2 | 6 y | C | 8 | MVSD 10 then MVSD 12 then AVP II 12 | AVP II 12 Emb to RPA/snared | ADO 12/10 |
| 3* | 20 mo | C | 4 to 5 | ADO 8/6 | Emb to LPA/snared | AVP II 8 mm |
7‐LPA indicates left pulmonary artery; ADO, Amplatzer Ductal Occluder; AVP, Amplatzer Vascular Plug; Emb, embolization; MVSD, Amplatzer muscular VSD device; PDA, patent ductus arteriosus; RPA, right pulmonary artery; VSD, ventricular septal defect.
*
In a case of PDA and coarctation, after partial expansion of the stent, the ADO embolized into the LPA and was retrieved. The partially expanded stent was pulled down the aorta to the level of the diaphragm and an AVP II was placed in the PDA, the partially expanded stent was pushed back up to the level of the coarctation and fully expanded and then the PDA device was released from the cable.
