Event Description
|
As reported during a procedure to treat a ruptured aneurysm with a web device, multiple unsuccessful attempts were made to detach the web device form the pusher wire.The physician decided not to remove the web once it was deployed as the physician thought it would do more harm to the patient to remove it.The physician ended up leaving the web in place and cutting the delivery wire at the groin.The web and delivery wire were left in the patient.The placement of the web was not ideal, and a stent was placed so it would not move.There are no plans to address the pusher, other than leaving it in patient.The patient was reported to be doing poorly and was sent home on hospice.

Manufacturer Narrative

Additional information was received for medwatch report (mw5111148) on aug 30, 2022, containing cds images.No product was returned for evaluation, but several dicom image series were provided.The images show the web well positioned in the aneurysm, then sitting lower over time.A microcatheter is observed in the left a1 and a stent bridges the left a1 and the proximal left a2.The web is observed in the aneurysm with the pusher seen proximally in lica.The non-detached pusher wire extends from the web down the left a1, intracranial left ica to mid-cervical spine level, where the scan ends.There is infarction of the entire left aca territory (as evidenced by hypodensity), with mass effect and midline shift.The remainder of the pusher wire extends from the thoracic aorta, through the abdominal aorta, the common and external iliac arteries, and ends in the proximal femoral artery.These images confirm the complaint and show the web still attached to the pusher; however, the reason for the non-detachment of the web is not seen in these images.Without the return and physical evaluation of the device, the investigation is unable to determine if a condition existed that would have caused or contributed to the reported event.
