Fluoroscopic removal of fractured, retained, embedded Z self-expanding metal stent using a guidewire lasso technique: A case report

Figure 3 Balloon dilation performed approximately 40 d after stent removal. A: Chest enhanced computed tomography examination showed obvious thickened esophageal wall (arrow); B: Esophagography showed severe stenosis (arrow) in the proximal part of the esophagus. C: A 28 mm in diameter and 40 mm in length big balloon catheter was used to dilate the stenotic section; D: Esophagography showed that the stenosis (arrow) disappeared after dilation.
