It was reported that the stent damaged, obstruction occurred and required additional intervention.The 80% stenosed target lesion was located in the moderately tortuous and non-calcified left main (lm) and left anterior descending artery (lad).A 2.50 x 23 mm non-boston scientific stent was implanted into the distal end of the blood vessel, and then, a 3.00 x 20 mm promus premier stent was overlapped about 10mm in the non-boston scientific stent.The physician was preparing to retract the promus premier stent towards the proximal end of the blood vessel.However, it become stuck with in a non-boston scientific stent.It was noted that the physician thought the stent had a rough edge.There was concern that forcefully pulling the promus premier stent out could lead to patient complications.On angiography, it was noted a "smoke" was seen, and blood flow was found to be blocked, causing risk of ischemia.The stent did not completely cover the lesion, and another stent was implanted.The patient did not complain of discomfort during the procedure.
