It was reported an endovascular aneurysm repair (evar) was performed.The stent graft used in the procedure was made by another manufacturer.After the deployment of the other manufacturer's stent graft, a type ia endoleak was visible.A coda balloon was used as to perform touch-up ballooning at the proximal site of the stent graft.During touch-up ballooning, a dissection occurred near the left renal artery.It was reported that touch-up ballooning was sometimes conducted while the balloon protruded from the stent graft.No additional treatments were performed for the dissection, and this medical case got a follow-up examination.Additional information has been requested.At the time of this report no additional details are available.

It was reported in additional information provided on 28may2019, that when the physician used a coda balloon during the evar + ibe procedure, it protruded from the main body a bit.The physician had never experienced the dissection of the proximal side of the zenith before, but stated that, "i should have been a bit more careful about the existence of suprarenal stents when i conducted touch-up ballooning." the physician does not think that coda-2-9.0-35-120-32 contributed to the incident.There were no problems noted with the access route.
