Abstract

To report a case of acute arm ischemia and prosthetic shoulder infection treated by extra-anatomical great saphenous vein graft with external vascular scaffolding.A 65 years-old man with multiple surgical interventions for soft tissue sarcoma of right shoulder, local radiotherapy with residual brachial plexus neuropraxia, was referred to our attention for signs of arm ischemia. Two weeks before, patient was submitted to prosthetic shoulder replacement complicated with prosthetic infection.Considering the mechanism of vascular injury an open surgical revascularization was planned with a deliberate avoidance of the natural anatomic pathway to reduce the risk of graft infection.Consequently, after the complete removal of infected shoulder prosthesis and placement of antibiotic spacer, an axillar-brachial artery bypass using great saphenous vein was performed using a new braided cobalt chrome kink resistant external vascular support to prevent compression, also considering the extra-anatomical position of the graft. At 12 months’ follow-up, patient was in good clinical condition with complete resolution of arm ischemia; computed tomographic angiography and duplex scan revealed patency of the graft with excellent distal perfusion.The new external vascular support seem to be useful and feasible for prevent compression of extra-anatomical venous bypass.
