Event Type  Injury  
Event Description
On (b)(6) 2023, the patient underwent endovascular treatment of an ascending thoracic aortic dissection using gore® tag® thoracic branch endoprostheses (tbe).The entry tear was observed in the aortic arch at the level of the distal anastomosis proximal to the patient's left subclavian artery (lsa).The length from the distal border of the lsa to the beginning of the entry tear was approximately 2.7cm by outer curve length.A thoracic aortic component and a side branch component were implanted.A proximal type i endoleak was observed on the aortic component, so an aortic extender component was implanted to treat the endoleak.The endoleak remained, so the physician opted to reline the tbe system with a gore® tag® conformable thoracic stent graft with active control system (ctag a/c).The side branch portal was intentionally covered and a vbx device was used to extend from the side branch distally in a periscope technique.The distal end of the vbx device was landed approximately 1.3cm from the distal end of the ctag a/c device.On (b)(6) 2023, the gore representative became aware of follow-up ct imaging which reportedly revealed a distal type i endoleak and suspected gutter leak from the vbx and ctag a/c device.On (b)(6) 2023, the patient underwent reintervention of the endoleaks.An additional ctag a/c was implanted.It was reported that the distal end of the newly implanted ctag a/c device extended passed the initial ctag a/c device.The endoleaks were resolved.Pre-implantation cta dated (b)(6) 2023, and post-implantation cta dated (b)(6) 2023, were provided to gore for evaluation.The imaging evaluation showed contrast in the false lumen perfusing from the level of the lsa.The ctag a/c device, tbe aortic component, and tbe aortic extender component appeared to have adequate overlap and appeared to cover the area where the contrast origin perfusing the false lumen was questionable, thereby, excluding them from a type i endoleak.However, the vbx device, used to extend the tbe side branch component distally, did not overlap with the proximal end of the side branch component as is extends into the lsa.The distal end of the vbx device was landed approximately 1.3cm from the distal end of the ctag a/c device.This finding suggested that the contrast outside the implanted devices at the level of the lsa may have been originating from a possible gutter leak involving the side branch component.

Event Description
On (b)(6) 2023, the patient underwent endovascular treatment of an ascending thoracic aortic dissection using gore® tag® thoracic branch endoprostheses (tbe).The entry tear was observed in the aortic arch at the level of the distal anastomosis proximal to the patient's left subclavian artery (lsa).The length from the distal border of the lsa to the beginning of the entry tear was approximately 27mm by outer curve length.A thoracic aortic component (tac083415) and a side branch component (tsb081206) were implanted.The proximal segment length on the tac083415 is 20mm and, therefore, landed in dissected tissue and did not cover the primary entry tear.The physician extended proximally with an aortic extender component (te3742).There was insufficient overlap between the aortic extender and aortic component leading to a type iii endoleak.To treat this endoleak, the physician opted to reline the tbe system with a gore® tag® conformable thoracic stent graft with active control system (ctag a/c).The proximal end of the ctag a/c was within the aortic extender.The side branch (sb) portal was intentionally covered and a gore® viabahn® vbx balloon expandable endoprosthesis (vbx) was used to extend from the side branch distally in a periscope technique.The distal end of the vbx device was landed approximately 1.3cm from the distal end of the ctag a/c device.On (b)(6) 2023, follow-up ct imaging revealed an endoleak and suspected gutter leak from the vbx and ctag a/c device.On december 12, 2023, the gore representative became aware of the endoleak event.On (b)(6) 2023, the patient underwent reintervention for the endoleak.An additional ctag a/c was implanted within the existing ctag a/c.It was reported that the distal end of the newly implanted ctag a/c device extended passed the initial ctag a/c device to intentionally cover and collapse the distal end of the previously implanted vbx sb extension.The endoleak was resolved and the physician bypassed the lsa to the left common carotid artery to maintain flow.A post-implantation cta dated (b)(6) 2023, was provided to gore for evaluation and showed contrast in the false lumen perfusing from the level of the lsa.The ctag a/c device, tbe aortic component, and tbe aortic extender component appeared to have adequate overlap and appeared to cover the area where the contrast origin perfusing the false lumen was questionable.This finding excluded the devices from a type i endoleak.However, the vbx device, used to extend the tbe side branch component distally, did not fully reline the side branch component proximally where the side branch component extends into the lsa.This finding suggested that the contrast outside the implanted devices at the level of the lsa may have been originating from a possible gutter leak involving the side branch component.The origin of the endoleak remains indeterminate.
