A Case of Axillofemoral Bypass Graft Stump Syndrome Occurring in Both the Upper and Lower Extremities / 日本心臓血管外科学会雑誌

ABSTRACT

Acute ischemia due to thromboembolism caused by occluded prosthetic graft after axillary-femoral artery bypass has been reported as axillofemoral bypass graft stump syndrome (AxSS). AxSS usually occurs in the upper extremities and it is rare that it occurs in the lower extremities. We encountered a rare case of a 76-year-old woman with acute right upper and lower extremities ischemia 4 years after right axillary-external iliac artery bypass grafting. The graft and the native arteries of the right upper and lower limbs were occluded. In addition, the right axillary artery and proximal anastomotic site were deformed. We diagnosed acute limb ischemia due to AxSS and immediately performed thrombectomy. Because we considered the thrombosis to originate from the axillary-iliac artery bypass graft, we disconnected the occluded graft from the native arteries. Six months after surgery, she was doing well without recurrence of thromboembolism. We report here the successful treatment of a case of AxSS that developed in both the upper and lower extremities.
