Acute kidney injury following percutaneous mechanical thrombectomy of subclavian artery stent graft thrombosis: a case report

Abstract

Abstract Background Percutaneous mechanical thrombectomy (PMT) is a well-established technique for treatment of acute arterial and venous thrombosis which inevitably leads to intravascular erythrocyte hemolysis, resulting in hemoglobinuria. Case presentation We present a case of 66-year-old Caucasian female with subclavian artery aneurysm causing distal embolization and hand ischemia. The aneurysm was treated with stent graft, but with a subsequent graft thrombosis 3 months later. After graft recanalisation, AngioJet PMT was performed which resulted in dialysis-requiring acute kidney injury. Conslusion Only several cases of acute kidney injury following AngioJet PMT have been published in literature. To our knowledge, this is the first reported case of dialysis-requiring AKI after PMT for peripheral arterial thrombosis. Until there is sufficient evidence and recommendation on preventing AKI in this setting, we believe that by being aware of the risk and by monitoring of patient, one might minimize the damage in case it occurs.
