Patient id: (b)(6).It was reported that on (b)(6) 2023 one 3.0x38 mm xience prime stent was implanted in the right anterior tibial artery (ata) and one 3.5x33 xience prime stent was implanted in the right peroneal artery.The patient was on dual antiplatelet medications.Eleven days after the stent procedure, the patient had lower limb ischemia, right foot pain at rest and dusky toes, resulting in hospitalization.Ultrasound showed 100% occlusion of sfa (superficial femoral artery), popliteal and ata stented vessel with no run off, and thrombus was found in both implanted xience prime stents and in the non-study sfa.Revascularization was performed on (b)(6) 2023 in the study lesions, anterior tibial artery and peroneal artery, with thrombectomy performed; however, the clot was unable to be extracted.Direct thrombolysis was performed.Revascularization was performed on (b)(6) 2023 in the study lesions, anterior tibial artery and peroneal artery, with thrombectomy performed; however, there was minimal success and thrombolysis was continued.On 09/25/2023, revascularization, balloon angioplasty, was also performed in the non-study sfa.Angiogram showed improved flow to all vessels.Rivaroxaban was started.The patient was discharged to home on 09/28/2023.

The device was not returned for analysis.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 effects of ischemia, pain and thrombosis are listed in the xience prime, xience prime small vessel (sv), and xience prime long length (ll), everolimus eluting coronary stent systems instructions for use as known patient effects of coronary stenting procedures.A conclusive cause for the reported patient effects, and the relationship to the product, if any, cannot be determined; however, the subsequent 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 xience prime device referenced in b5 is filed under a separate medwatch report number.
