Femoral approach Guiding catheter 6f jl 3.5 Guidewire 0.014 choice pt extra support Pre dilated with 2.5 x 15 mm balloon. Attempted  withdrawal Stent  dislodged from  balloon  into left- main  coronary  artery. Second  guide & wire  fromcontralateral  femoral, Stent  snaired out Successful  coronary  angioplasty using  another stent Patient  discharged  after three days.Patient againpresented with chest pain - AWMI.

Never withdraw the stent, Deploy there only, Carefulwithdrawal of stent in calcified vessel with proper alignment of guiding. Tryto withdraw stent, guide wire and guiding catheter as a total assembly. Snaringof stent from Left Main Coronary Artery technical expert required. Contralateral  femoral puncture  and  simultaneous wiring  if vessel goes into threaten occlusion beforeretrieval of previous wire. As previous wire will help in easy tracking down ofadditional wire. Double wire criss-cross technique. Crush the stent againstwall with another stent. Sub acute stent thrombus need aggressive management.
