[Vascular steal syndrome due to the creation of an arteriovenous shunt for hemodialysis, patient information and nephrologist responsibility]

Although responsibility is a fundamental determinant in medical practice, physicians are generally unfamiliar with its principles. The same is true for disclosure requirements and requests for compensation in the event of physical injury. We report on a representative survey of iatrogenic complications that may arise after the implementation of vascular access for haemodialysis and that illustrate's the physician's responsibility and obligation to inform the patient. Vascular access steal syndrome is a serious complication of arteriovenous fistulas, and physicians may not be sufficiently aware of the likelihood of its occurrence. Diabetes (via medial calcific sclerosis) and placement in the brachial artery (with excessively high flow rates) are the main risk factors. The precariousness of vascular status in dialysis patients threatens to increase the incidence of this complication. The therapeutic challenge is to resolve ischemic events while maintaining vascular access. The presence of gangrene of the fingers is a formal indication for surgery. The borderline between therapeutic risk (the risk inherent in a medical procedure and which cannot be controlled) and liability for injury is blurred. The French Patient's Rights Act (voted on March 4th, 2002) emphasizes the physician's duty to inform the patient of treatment-associated risks and the fact that the physician now bears the burden of proof. We suggest that a patient information sheet on the benefits and risks of vascular access should be published on the French Society of Nephrology, Dialysis and Transplantation's website.
