"death: on (b)(6), an emergency tevar was performed for an aortic dissection.The relay pro stent graft concerned (28-n4-32-209-28u, lot#: 2404170130) was implanted centrally and a relay pro stent graft (28-n4-32-164-28u, lot#: 2407130037) was additionally implanted peripherally.The procedure was completed without any problems with the procedure or the devices themselves.On (b)(6), the patient's condition suddenly changed, and the patient died.After death, a ct scan revealed that the internal pressure in the false lumen had increased due to the expansion of the true lumen caused by the implantation of the stent grafts, and the false lumen had ruptured around the abdomen.Physician's comment: the physician did the best that he could with the means available to the hospital.There was no other choice.Physician's comment on causal relationship: the means taken for the aortic dissection were the best, given the emergency treatment on (b)(6), but the true lumen expanded more than expected.Operation type: emergency tevar for an aortic dissection, no blood loss, ancillary device used: 28-n4-32-164-28u (lot#: 2407130037), no image available due to hospital policy, no pre-case plan available due to hospital policy, no additional information available due to hospital policy, (tc#: (b)(4))." patient outcome: "the patient died.".
