A 52-year-old female presented with acute anterior ST-elevation myocardial infarction (STEMI) within one hour of symptom onset to the emergency department. She was referred for urgent primary angioplasty.
Physical examination, laboratory investigations, ECG, urgent percutaneous coronary intervention (PCI).
Single-vessel coronary artery disease (SVD).
Intended to stent culprit lesion. However, stent dislodged in left main coronary artery (LMCA) during attempted PCI to diffuse mid segment of left anterior descending (LAD). Initial attempt failed to retrieve the dislodged stent with snare. Dislodged stent removed with multiple wire technique, complicated by severe dissection in LAD and left circumflex artery back into the LMCA. The stent was trapped at tip of 6 Fr right femoral sheath, unable to be withdrawn. What next?

打算支架置入罪犯病变。然而，在试图对左前降支（LAD）弥漫中段进行 PCI 时，支架在左主干冠状动脉（LMCA）内脱落。最初的尝试未能用圈套器取回脱落的支架。通过多根导丝技术取出脱落的支架，导致 LAD 和左回旋支严重夹层，并返回到 LMCA。支架被困在 6 Fr 右股鞘的尖端，无法撤出。接下来怎么办？
