The First Successful Transcatheter Closure of an Inferior Sinus Venosus Defect with Anomalous Drainage of the Right Lower Pulmonary Vein Using Bare and Covered Stents: A Single-Case Report

Figure 11

The covered stent (white arrow), which was placed second, is positioned superior to the anchored bare stent (black arrow) in the inferior vena cava ((a) anteroposterior and (b) lateral views on angiography). The placement of covered stent was supposed to be above the entrance of the right lower pulmonary vein (RLPV) but at the expense of overlapping segment because the bare stent was placed lower enough into the IVC. This can be compared with final position of the covered stent after repositioning almost covering the entrance of RLPV but lower than the first position (Figure 15). The stitch can be used as a guide line.
