As reported, the patient had a severe radial spasm while using a 6f rain sheath in a percutaneous coronary intervention (pci), which made the procedure difficult.The physician observed the radial spasm while using a guide catheter.After the procedure, nitroglycerin was administered however, the physician assistant was unable to withdraw the sheath.The patient was then given sedation to lessen discomfort and the sheath was pulled out.The lesion was not calcified, there was eighty percent stenosis and vessel tortuosity was moderate.The device was not used for a chronic total occlusion.The sheath size was appropriate for the vessel.The access site was not highly calcified.No anomalies were noted when the product was removed from the package.The product was stored, handled, inspected and prepped according to the instructions for use (ifu).The access needle was flushed prior to use, and the air was removed from the catheter sheath introducer (csi) through the side port extension by inverting and flushing with heparinized saline or suitable isotonic solution.The radial artery spasm occurred during the end of the intervention.The sheath was in place for thirty minutes and was not used for any infusions.The device was not caught in the vessel during removal.One non-sterile unit of 6f10cm pw22 radial was received for analysis.Only the cannula, vessel dilator and a mini guidewire were returned for analysis.During visual inspection, the cannula was observed compressed and kinked.The damage extended from 4cm to the distal tip to 10 cm from the distal tip.Inner diameter (id) and outer diameter (od) measurements were taken near the damages and were found within specification.A product history record (phr) review of lot 18071334 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The failure reported by the customer as " catheter sheath introducer (csi) - withdrawal difficulty¿ could not be properly evaluated and confirmed due the nature of the complaint.The reported radial artery spasm is the likely cause of the event.Arterial spasm is a known potential adverse event associated with any interventional procedure where devices are introduced into the vasculature.Local vasospasm can be caused by the device manipulations inherent in any procedure causing endothelial irritation.According to the instructions for use (ifu), although not intended as a mitigation of risk, ¿hold the sheath in place when inserting, positioning, or removing the catheter.Possible complications include, but are not limited to: abrupt vessel closure, additional intervention, allergic reaction (device, contrast medium and medications), air embolism, infection, intimal tear, hematoma at puncture, hemorrhage, inflammation / infection / sepsis, ischemia, perforation of vessel wall, thrombus formation, peripheral nerve injury, pain, vascular complications (e.G.Intimal tear, dissection, pseudo aneurysm, perforation, rupture, spasm, occlusion¿.Based on the information available and the phr review, there is no indication that the event is related to the device design or manufacturing process.Therefore, no preventative or corrective actions will be taken at this time.
