Event or Problem Description
The following information was reported to gore: on (b)(6) 2026, the patient underwent endovascular treatment of thoracic aortic dissection, zone 2, using gore® tag® thoracic branch endoprosthesis.A 20 fr gore® dryseal flex introducer sheath was introduced via the right femoral artery.Following deployment of the stent graft, access vessel angiography demonstrated vascular injury to the right femoral artery.As a treatment, a stent graft was implanted at the injured site, after which the procedure was completed.It was reported that the access vessel diameter was in the 6-mm range, which was considered relatively small and therefore associated with an increased risk of vascular injury.
