It was reported that partial deployment occurred resulting in a stretched stent.The target lesion was located in the moderately tortuous and moderately calcified superficial femoral artery (sfa).Two 7x120, 130 cm eluvia drug-eluting vascular stent systems were selected for use.Balloon angioplasty was performed in the long segment sfa.Some recoils and dissections were noticed, so it was decided to stent with eluvia stent.Deployment was attempted with the first eluvia stent using the thumbwheel.The thumb wheel would no longer work to finish deployment leading to partial deployment and the last half centimeter getting stuck in the deployment system.In order to get the last half centimeter of the stent out of the deployment system, the physician had to pull the delivery system with the stent still attached resulting in severe elongation and stretching of the stent.The same issue was encountered when the physician attempted to deploy the second stent.The patient fully recovered.
