Event Description

An attempt was made to implant a valiant stent graft in a patient for the endovascular treatment of a 60mm fusiform thoracic aortic aneurysm.It was reported there were two double back curves in the aorta and the gothic arch.Extreme vessel tortuosity was noted in the thoracic aorta.It was reported that, during the index procedure a 24fr sentrant sheath was placed in the femoral artery to assist with delivery of all planned stent grafts.The 24fr size was chosen as the size of the primary stent graft (valiant 40x40x200).It was reported that, due to the extreme touristy of the anatomy the physician initially elected to use another manufacturer thoracic stent graft to try to straighten out the aorta in order to pass the valiant devices.It was reported that the physician went in and out of the sentrant sheath several times and found the 24fr sentrant was very tight.It was reported it required a lot of strength to get the non-mdr stent graft up and that the non-mdt stent graft could not be deployed.The physician then attempted to insert the valiant delivery system but again it was reported as extremely difficult to pass the valiant delivery system through the sentrant sheath.The 24fr sentrant sheath was then swapped for a 26fr sentrant sheath but again the physician was unable to pass the valiant delivery system.The physician then attempted to insert the valiant delivery system barebacked into the vessel however it became stuck there.A body floss technique using a snared stiff wire was used to deliver the device to the final curve however while advancing the delivery system to the target landing zone it could not get past the gothic arch.After a number of attempts and reexamination of the ct, the physician decided to abort the procedure.Per the physician the sentrant sheath could have been damaged by the non-mdt stent graft or possibly by a bur on the graft of the valiant device.No additional clinical sequelae were reported and the patient will be monitored.

Manufacturer Narrative

Films review summary: the exact cause of the insertion and positioning difficulties encountered during implant could not be determined from the limited films provided.However, it appears likely that the tortuous thoracic anatomy may have contributed to the events.Complete pre-implant ct¿s were not provided and a comprehensive review of the patients anatomy could not be assessed.In addition, films during implant were not available and the reported events also could not be reviewed.A short (15 second) video of a pre-implant ct was returned.No scale was seen on the returned images; therefore, no vessel measurements could be performed.The film was a coronal slice showing the left side of the chest and included the entire length of the thoracic aorta, as well as the abdominal aorta down to the origin of the iliac arteries.The iliac and access vessels were not seen in the returned films and could not be assessed.The thoracic aorta was noted to be dilated and moderately calcified along nearly the entire length, as well as moderately tortuous.Two (2) acute bends were observed on the descending aorta.The more proximal bend near the level of the aortic valve implant was angulated >90 deg medially; lt-rt.After traversing to the patient¿s right side a short distance, the descending thoracic was seen sharply angulated (~90 deg; rt-lt) inferiorly, and then descended essentially straight down to the visceral vessels.Note that only a single anatomical orientation was seen from this coronal slice, and any possible additional a-p angulation could not be assessed.The entire abdominal aorta was noted to be straight but extensively calcified.In addition to implanting into the tortuous and calcified anatomy, an unknown interaction between the other manufacturer¿s stent graft and the sheaths may have also contributed.An issue with the device and/or sheaths cannot be ruled out as a potential cause.However, the devices were discarded and product investigation could not be performed.If information is provided in the future, a supplemental report will be issued.
