The devices were not returned for evaluation.Without return of the units it is not possible to determine if some damage or defect existed on the units that could have contributed to the event.It is not known if some procedural factors may have contributed to the event.No corrective actions will be taken at this time.Lot number was not provided; therefore, review of the manufacturing records could not be completed.An investigation has been initiated to consider any potential manufacturing factors that may have contributed to this complaint.Per the ifu, the arterial embolectomy catheter is not recommended for the removal of fibrous, adherent, or calcified material (e.G.Chronic clot, atherosclerotic plaque).The catheter is not designed to withstand the additional force needed to remove these materials.Balloon rupture and catheter separation as a result of excessive pull force applied to remove adherent material are the most frequent causes of reported failures.The possibility of balloon rupture must be taken into account when considering the risks involved any embolectomy procedure.As with all catheterization procedures, complications may occur.These may include local or systemic infection, local hematomas, intimal disruption, arterial dissection, perforation and vessel rupture, hemorrhage, arterial thrombosis, distal embolization of blood clots and atherosclerotic plaque, air embolus, aneurysm, arterial spasm, arteriovenous fistula formation, and balloon rupture with fragmentation and distal embolization.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.Cho, s.B., choi, h.C., lee, s.M., na, j.B., park, m.J., shin, h.S.,.& park, s.E.(2019).Combined treatment (image-guided thrombectomy and endovascular therapy with open femoral access) for acute lower limb ischemia: clinical efficacy and outcomes.Plos one, 14(11), e0225136.Medwatch number 2015691-2020-13600 cross references the complaints for arterial extravasations.

It was reported that in a journal article published in 2019 and titled ¿combined treatment (image-guided thrombectomy and endovascular therapy with open femoral access) for acute lower limb ischemia: clinical efficacy and outcomes¿ 52 patients underwent combined treatment for acute thrombotic occlusion of lower extremity arteries.In 10 patients using fogarty catheters, there were 5 cases of extravasation and 5 cases of arterial dissection.The arterial extravasations were: one popliteal, three peroneal, one posterior tibial.The popliteal artery was treated with embolization and stenting, one peroneal artery was embolized with microcoils while the two peroneal arteries and one posterior tibial artery could be treated with long-duration balloon inflations.Model and lot numbers are unknown.As well as any specific patient demographics.The devices were not saved for examination.
