Event Description

On (b)(6), 2023, this patient underwent endovascular treatment for a thoracic aortic dissection and penetrating aortic arch ulcer and was implanted with gore® tag® thoracic branch endoprostheses (tbe).An open surgical procedure was not an option due to patient condition and access was obtained in the abdominal aorta.The patient had previously received a procedure to bypass the lsa to the lcca and bca.The patient had an existing cabg coming off the mid-bca and a lima bypass off the lsa.Prior to placement of tbe, the patient was hypotensive with increased pressure in the left arm compared to the right.The tbe was placed with the side branch in the lsa and with intentional partial coverage of the bca proximally with the aortic component (ac).It was reported that the portal opening on the gore® tag® aortic component (tac123715a/25765796) had landed slightly distal to the lsa, leaving placement of the side branch (tsb121506a/26679693) a little compressed.Post operative cta demonstrated a moderate stenosis in the compressed portion of the side branch.A gore® tag® conformable thoracic stent graft with active control system (tgmr373710/23079450) was placed proximally to the tac to extend treatment into the ascending aorta.Due to this device configuration, all blood flow to the lcca and bsa was through a single side branch in the lsa.On (b)(6), 2023, the patient underwent reintervention on the tbe side branch and a gore viabahn vbx balloon expandable endoprosthesis (bxa115902a/27134726) was implanted to open the compressed region.The patient tolerated the procedure.The physician suspects (but was unable to confirm) that the patient may have experienced a small transient ischemic attack (tia) over the weekend due to the compressed side branch.No major stroke was reported, and the patient is reported to be doing better.On december 1, 2023, it was reported that the patient had expired on an unknown date, a cause of death was not provided.On december 7, 2023, the physician provided additional details.The patient expired on (b)(6), 2023.The physician listed the cause of death as cardiorespiratory failure likely related to the device.Compromised flow through the side branch was suspected to be a factor, although completion angiogram did not suggest this.
