Event or Problem Description
A valiant navion thoracic stent graft was implanted for the treatment for a thoracic aortic aneurysm.It was reported that a ct performed approximately 6 months post index procedure identified a type ia endoleak.A secondary procedure was performed approximately 7 months post index procedure with the indication of aneurysm growth.It was reported on examination of the ct (b)(6) 2019) it also appeared that the original endograft had migrated somewhat from the left subclavian artery.During the intervention, the type ia endoleak was confirmed on aortogram.A 34mm valiant navion stent graft was implanted.A completion angiogram demonstrated residual leak into the proximal descending thoracic aorta.Ballooning with a reliant was attempted however this resulted in some downward displacement of the graft.The physician elected to implant a second component (34 mm in diameter uniformly and 10 cm in length).This was passed over a non mdt wire and deployed.There was still a slight blush of contrast into the thoracic aorta along the inferior border but the previous leak along the upper border was absent.Considering this a satisfactory revision the physician ended the procedure.As per the physician it was unable to be confirmed if blush noted post the intervention procedure was a type i or type iv however it was reported that on follow up ct on (b)(6) 2019 showed no endoleak.The most recent ct on (b)(6) 2022 also shows no endoleak and stable aneurysm size.The patient has had a total of 8 scans in a 3 year period following this 2nd procedure and none of them have showed an endoleak.The patient has presented to the emergency room at times with complaints of chest pain and undergone scans at those visits as well.When the initial navion graft was deployed at the time of the original surgery, it seemed jump back distally during the deployment from where it was anchored just at the take-off of the left subclavian artery during the deployment.It then deployed about 1-2 cm short of the take-off of the left subclavian artery.Intraoperative arteriography showed no evidence of endoleak.The initial cta scan in follow up performed on 18-jun-2019 showed the type i endoleak.This was probably due to inadequate length of a landing zone from the initial deployment.Elective repair was scheduled when the patient presented to the emergency room with complaints of chest pain on 24-jul-2019 with cta showing the same endoleak which was then repaired on 26-jul-2019.The physician noted that it is not considered that the initial graft failure with the type ia endoleak is due to stent ring enlargement or fracture of the navion graft, but due to enlargement of her native aneurysm with likely an inadequate length of landing zone at the initial graft deployment.No additional sequelae was provided and the patient is fine.
