Event Description
|
It was reported that the procedure was to treat a de novo, mildly calcified and mildly tortuous vessel in the superficial femoral artery (sfa).The vessel diameter was 5.0mm.Pre-dilatation was not performed and atherectomy was not used.Because there was a lesion in both (left and right) vessels, puncture was done antegradely from left sfa and a 5.0x80mm supera self expanding stent was implanted in left sfa.Then, approach was changed to cross-over approach technique, total occluded lesion at right popliteal vessel was attempted to be treated.A guide wire was attempted to cross the lesion, but it failed to cross.When the last fluorography was done, dissection at left sfa was noted.The 5.0x40mm supera sess was implanted to treat the dissection but the stent became elongated [stretched] because of no pre-dilatation.There was no resistance during advancement.Post-dilatation was performed to treat the dissection.However, it was noted that the tip of the sess had separated and remained in the patient's body floating freely distal of the stent at sfa but no blood flow distal of p1.The thumb slide was not fully retracted to the start position and both the system and deployment levers were not locked prior to removal.The physician did not rotate the system lock and the deployment lock into the locked position (in line with the thumb slide).The delivery system was removed without fluoroscopy.The aortic bifurcation was at the usual angle.The patient condition was not stable since the patient's age was in the 90's and the procedural time was long.The procedure was completed with decision that the remained tip will be removed when amputation surgery is performed at a later day because there was no blood flow distal to the lesion which was a pre-existing condition.No additional information was provided.

Manufacturer Narrative
|
The device was not returned for evaluation.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.The reported patient effect of dissection is listed in the supera peripheral stent system instructions for use (ifu) as a potential adverse effect of peripheral percutaneous intervention.A conclusive cause for the reported patient effect, and the relationship to the product, if any, cannot be determined.However, the treatment appears to be related to the operational context of the procedure.There is no indication of a product quality issue with respect to manufacture, design or labeling.The additional supera referenced is being filed under a separate medwatch report number.
