[Hybrid surgical treatment of false aneurysm of proximal anastomosis after aortobifemoral bypass grafting (case report)].

One of formidable complications of aortobifemoral bypass grafting or prosthetic repair is a false aneurysm of a proximal anastomosis. Clinical guidelines propose treatment using relaparotomy. We describe herein a clinical case report regarding a 66-year-old male patient primarily operated on for lower-limb critical ischaemia in 2011, undergoing aortobifemoral bypass surgery and femoropopliteal bypass grafting on the right. In 2018, he again presented to our Clinic, complaining of acute abdominal pain. Examination revealed a false aneurysm of the proximal aortobifemoral bypass graft, followed by operative intervention, i. e., endoprosthetic repair of the defect of the proximal anastomosis, reconstruction of the right distal anastomosis of the aortobifemoral bypass graft. The shunt has been functioning for 4 years, with no evidence of either paraprosthetic infection or critical ischaemia.
