Manufacturer¿s ref.No: (b)(4).Information regarding patient identifier, date of birth, weight, race, ethnicity, and medical history were not provided.The name, phone and email address of the initial reporter are not available / reported.Patient codes: the fda code: no code available fda (b)(4) was chosen to capture the surgical intervention in the use of emergent coil embolization.[conclusion]: the healthcare professional reported that the 5 x 33mm embotrap ii revascularization device (et009533 / 19d099av) was used during a mechanical thrombectomy procedure to treat an acute ischemic stroke, as the thrombus was being removed, the patient¿s blood vessel was injured.The patient developed a subarachnoid hemorrhage (sah) which required emergent coil embolization.The current status of the patient is not known.The physician commented that ¿the event might have caused by the patient¿s blood vessel whose atherosclerosis had developed and the wall had been damaged, therefore, not only the complaint device but also other stent retriever might have brought similar cases if they used.¿ based on complaint information, the device was not available to be returned for analysis.A review of the device history record (dhr) associated with this lot (19d099av) top and sub assembly presented no issues during the manufacturing or inspection processes related to the reported complaint.There were no non-conformances related to device manufacture or inspection.All product rejected during manufacturing was identified as scrap and properly accounted for.Product analysis cannot be conducted as the product was not returned for analysis.There was no report of any device malfunction.As such, the investigation will be closed.Vascular injury and hemorrhage are well-known extensively documented potential complications associated with endovascular mechanical thrombectomy for acute ischemic stroke cases and are listed in the embotrap instructions for use (ifu) as such.The root cause of the event cannot be determined without procedural films; however, clinical and procedural factors including vessel characteristics, tortuosity, device selection, and mechanical manipulation of devices within the artery are all factors that may contribute to vascular injury or perforation.There was no report of a device malfunction or performance issue associated with the event.The reporting physician also stated that the patient had pre-existing atherosclerosis.As part of the post market surveillance program, information from this complaint is trended for statistical signals and corrective/preventive action may be triggered at a later time.Since there was no evidence to suggest the event of failure to detach was related to a manufacturing or design issue, no corrective actions will be taken at this time.Missing information from this report is identified as blank; this information was not provided in the reported event or available at the time of report submission.The manufacturer will submit a supplemental report if new facts arise which materially alter information submitted in a previous mdr report.Additional information will be submitted within 30 days of receipt.
