[Aortocoronary bypass, haemodialysis and internal mammary artery steal].
The dramatic occurrence, during haemodialysis sessions, of hemodynamic and cerebral symptoms in a 53-year-old haemodialysed woman with a history of aortocoronary bypass leads to discovery and treatment by percutaneous angioplasty and stenting of a significant stenosis of proximal subclavian artery, ipsilateral to the arteriovenous fistula, with retrograde flow in internal mammary artery graft and vertebral artery. All symptoms resume after interventional radiology. Analysis of literature confirms possibility of coronary artery steal induced by use of the arteriovenous fistula in haemodialysed patients with ipsilateral internal mammary bypass, especially if there is concomitant subclavian artery stenosis, and leading us to discuss the diagnostic and therapeutic implications.
