complaining of right arm and leg weakness, expressive dysphasia and confusion.An urgent ct scan was performed, and this did not reveal any acute stroke or hemorrhage.The patient was treated

and leg weakness resolved, he was less confused but still had some residual expressive dysphasia.A left carotid stenting procedure was being performed.Under ultrasound guidance a left common femoral artery puncture was performed and a short 6 inserted.The patient was 5000 units of heparin intravenously.Selective catheterization was performed to the left common carotid artery using a 5 french catheter.Angiography demonstrated a high-grade focal stenosis at the origin of the internal carotid artery.A long 6 french sheath was inserted into the common carotid artery.The stenosis was crossed intraluminal using a 5 mm angioguard.The stenosis was predilated uneventfully using a 3 mm x 4 cm balloon.An 8 mm x 4 cm cordis precise stent was deployed uneventfully.The stent was post-dilated uneventfully using a 5 mm x 4 cm balloon.There was still a residual stenosis and therefore further balloon dilatation was attempted using a 6 mm x 4 cm balloon.There was marked resistance to during the distal portion balloon catheter over the guide wire.Numerous maneuvers were attempted to remove the balloon catheter is all unsuccessful.Considerable force was required, and this resulted in movement of the angioguard filter protection device.The force needed to remove balloon which resulted in movement of the angioguard filter protection device which resulted in severe spasm in the left internal carotid artery.Eventually the balloon was removed.Attempts were made to remove and close the filter protection device.This was also problematic due to the presence of a large amount of fresh thrombus in the distal filter.This was eventually removed partially collapsed.The sheath was withdrawn from the carotid artery and a large amount of thrombus aspirated.Eventually the left carotid artery cleared.There was no obvious result filling defect and the intracranial circulation appeared preserved.An angioseal was deployed to the groin to achieve hemostasis.The aviator will be returned for analysis.The device was returned for analysis.One non-sterile rx/5mm basket diameter/180cm was received for analysis inside a plastic bag.Capture sheath was returned.Per visual analysis, the angioguard filter basket was observed fully deployed.No other anomalies were observed.Functional analysis could not be performed due to the deployed condition observed on the basket of the unit, as received.No lot number was provided therefore a product history record (phr) review could not be generated.The reported ¿ecgw (embolic capture guidewire) - resistance/friction - during withdrawal of sds¿ was not confirmed since functional analysis couldn¿t be performed due to the deployed condition observed on the basket unit.The reported arterial spasm and stroke were not confirmed since the event reported cannot be properly evaluated due to the nature of the complaint.Procedural and/or handling factors might have contributed to the reported condition of the unit since the device did not present any obvious indication of manufacturing defect or anomaly that could contribute to the event as reported.With the limited amount of information available regarding lesion characteristics and without the return of all the devices for analysis it is difficult to draw a clinical conclusion between the devices and the events reported.Risks associated with angioplasty procedures include arterial spasm and stroke.In this case (arterial spasm and stroke was specifically reported).These are well-known and extensively documented potential complication of this type of procedure and is listed in the instructions for use (ifu) as such.Vessels that are resistant to angioplasty have a higher risk of intimal plaque rupture during interventional procedures.Review of the available information suggests that these lesion characteristics and possibly procedural factors may have contributed to the withdrawal difficulty.During the investigation conducted, it was reported that ¿numerous maneuvers were attempted to remove the balloon catheter is all unsuccessful.Considerable force was required, and this resulted in movement of the angioguard filter protection device.The force needed to remove balloon which resulted in movement of the angioguard filter protection device which resulted in severe spasm in the left internal carotid artery.Eventually the balloon was removed.¿ therefore, it can be concluded that the operator¿s interaction with the balloon catheter (considerable force required) caused movement of the angioguard, resulting in an arterial spasm which resulted in the patient experiencing stroke like symptoms.The operator¿s direct interaction with the devices caused the reported events.A calcified/resistant lesion can cause damage to the balloon and result in vessel damage during angioplasty.According to the instructions for use ¿prior to use, the device should be examined to verify functionality and integrity and ensure that its size is suitable for the specific procedure.Do not exceed the rated burst pressure recommended on the label.The rated burst pressure is based on the results of in-vitro testing.At least 99.9% of the balloons (with a 95% confidence) will not burst at or below their rated burst pressure.Use of a pressure-monitoring device is recommended to prevent over-pressurization.Use only the recommended balloon inflation medium (a 50/50 mixture by volume of contrast medium and normal saline).Never use air or any gaseous medium to inflate the balloon.Potential complications, which may lead to additional intervention, include, but are not limited to: embolism, hemorrhage, stroke, thrombosis, transient ischemic attack, vascular complications (e.G.Intimal tear, dissection, pseudoaneurysm, perforation, rupture, spasm, occlusion).¿ furthermore, it was reported that ¿attempts were made to remove and close the filter protection device.This was also problematic due to the presence of a large amount of fresh thrombus in the distal filter.This was eventually removed partially collapsed.¿ however, in the instructions for use (ifu) it clearly states the following ¿how to detect if the angioguard rx emboli capture guidewire is full 1.Once the angioguard rx emboli capture guidewire is deployed in the vessel, it may capture emboli during the entire time of the interventional procedure.Therefore, it is recommended to check the status of the angioguard rx emboli capture guidewire at regular intervals during the intervention.2.Using fluoroscopy, perform a distal dye injection through the guiding catheter or interventional sheath introducer and observe the flow of dye distal to the filter basket or distal marker on the guidewire.3.If the distal perfusion of dye is significantly reduced or no dye is perfusing past the filter basket or guidewire distal marker band, the angioguard rx emboli capture guidewire may have reached its capacity to contain emboli.If there is a severe reduction in distal dye perfusion, it is recommended to exchange the angioguard rx emboli capture guidewire for a new one.¿ to exchange an angioguard rx emboli capture guidewire system that has captured its capacity of emboli the operator must follow the instructions for use in its entirety.If the operator would have followed the instructions for use properly, the operator would have read that ¿note: the emboli that have been captured may not allow the angiogard rx emboli capture guidewire to reach its initial low profile.¿ in conclusion, no procedural films nor images were provided for the reported adverse events of arterial spasm and stroke.Neither the phr, the analysis for the returned devices nor the information available suggests a design or manufacturing related cause for the reported events.Therefore, no corrective or preventive action will be taken at this time.This is one of three devices associated with the reported event.The two related report numbers are 9616099-2021-05043 and 9616099-2021-05044.
