case_images: (a) The reconstructed CT image showed that the stent was continuous, and a slight included angle was visible at the place where the stent entered the inferior vena cava on day 28 of postprocedure date. (b) The upper end of the bare stent was broken and free, which was located at the entrance of right atrium on day 236 of postprocedure date. (c) Inferior vena cava mural thrombus could be seen between intrahepatic part and free part of rapture stent as shown by red arrow on day 237 of postprocedure date. (d) No obvious progress of mural thrombus was indicated as shown by red arrow on day 250 of postprocedure date. (e) Chest CT imaging showed that the free part of raptured stent was moved into the right lower pulmonary artery as shown by red arrow on day 265 of postprocedure date. (f) CT enhancement imaging of Affiliated First Hospital of Medical School of Zhejiang University showed no change in the position of intrahepatic stent, smooth blood circulation, and no residual free part in the right atrium on day 265 of postprocedure date.. CT, computed tomography.

case_images: On day 28 of postprocedure date, a postoperative computed tomography (CT) scan suggested that the bare stent was intact with a slight angle at the place where it entered the inferior vena cava [Figure 1(a)]. On day 236 of postprocedure date, portal vein CT venography (CTV) revealed that the upper part of the bare stent had ruptured, and its free end located at the entrance of the right atrium [Figure 1(b)]. In addition, an inferior vena cava mural thrombus was observed between the intrahepatic part and the free part of the ruptured stent [Figure 1(c), red arrow]. On 8th-9th month after the postprocedure date, the free part of the ruptured stent migrated further to the entrance of right atrium with no significant changes in mural thrombus [Figure 1(d)]. However, 1 day before the planned surgery, the fractured stent moved to the right lower pulmonary artery without thrombus or dyspnea [Figure 1(e)]; enhanced CT scan showed no changes in the position of the intrahepatic stent and no residual stent found in the right atrium [Figure 1(f)].
