Mesenteric and coeliac occlusions following heparininduced thrombocytopenia after aortobiprofunda bypass surgery

Abstract

A 56-year-old man developed mid-gut bowel ischaemia following an elective aortobiprofunda bypass for short-distance claudication. The bowel was resected and he was commenced on lifelong total parenteral nutrition. He was found to have developed heparin-induced thrombocytopenia and thrombosis,confirmed by high levels of heparin-platelet factor 4-antibody on enzyme-linked immunosorbent assay (ELISA). He subsequently had foregut ischaemia with a second bout of thrombocytopenia despite not being on heparin. The case describes the first report of bowel ischaemia as a consequence of heparin-induced thrombocytopenia causing sequential superior mesenteric and coeliac arterial thrombosis in this scenario and highlights the importance of the awareness of the association of these pathological entities and subsequent management.
