The following information was reported: this patient is a man in his (b)(6).On an unknown date, the patient fell during snowboarding.Three days later, swelling and pain in the right shoulder got worse, and the patient was referred to the hospital.Computed tomography angiography (cta) was performed, and pseudoaneurysm and arteriovenous fistula in the distal portion of the right axillary artery was suspected.The patient was in poor general condition due to bleeding, and had disseminated intravascular coagulation (dic), so it was elected to utilize gore® viabahn® endoprosthesis with heparin bioactive surface (viabahn device).A micro guidewire was inserted from the right upper arm and a snare system was inserted from the right common iliac artery to apply pull-through technique.The viabahn device was implanted in the target lesion with no reported issue.Three days after the procedure, cta confirmed that the pseudoaneurysm and the arteriovenous fistula were disappeared.The patient discharged from the hospital seven days after the procedure.After the procedure, the patient was monitored with dual antiplatelet therapy (dapt).Four months after the procedure, computed tomography showed a middle stenosis around proximal portion of the viabahn device and mild stenosis located distal to the first stenosis region.However, at that time, contrast effect remained in its distal area.(reported previously under mfr report # 2017233-2019-01082) two years after the procedure, the patient underwent a re-intervention using a cutting balloon (6 mm/2 cm) and a non-compliant high pressure balloon (7 mm/4 cm) for the stenosis.
