Abstract
Background Graft infections of supra-aortic bypasses are rare, but often life-threatening. Guidelines for treatment of graft infections recommend systemic antibiotics and complete graft removal, followed by in-situ or extra-anatomic revascularisation. Methods Based on case report, literature search was performed on Medline, Google Scholar and Web of Science databases, focussing on infected supra-aortic bypass reconstructions. Inclusion criterium was prosthetic graft infection, excluding stent and carotid patch infections. Results A 68-year old man with clinically infected subclavian-subclavian bypass with interposition bypass to left carotid bifurcation, presented at emergency department with manifestation of sepsis. A total graft removal and an extra-anatomical prosthetic reconstruction was created, from right common carotid artery to left carotid bifurcation. Defect of prior left subclavian anastomosis was primarily closed, on right subclavian anastomosis per-operative acute bleeding occured, which was controlled by covered stent through right brachial artery. Literature review identified 16 cases. Different approaches ranging from open repair with autologous (six) or allogenic (two) material, to hybrid techniques (eight) have been described. No re-infections were reported. When comparing different types of approaches, no differences are found concerning overall complications. Conclusion Complete graft removal with extra-anatomical reconstruction is challenging, but crucial in supra-aortic graft infections. Preservation of parts of vascular prosthesis depends on case-by-case basis, according to infection site and general condition of the patient. But due to rarity, only case reports are available, so no strong recommendations can be formulated. International registries should be initiated to share experiences and provide data for decent analysis of short, mid and long term outcomes.
