Abstract
Children supported by extracorporeal membrane oxygenation present a high risk of neurological complications. Although carotid cannulation is known to be associated with neurologic injury, conflicting data exist with regard to the predominance of right- or left-sided lesions. We describe here two infants requiring veno-arterial extracorporeal membrane oxygenation for septic shock who encountered right watershed infarction ipsilateral to carotid artery cannulation. Hemodynamic failure seems to be the most probable underlying mechanism. The asymmetry of transcranial Doppler metrics in one case and the low right regional cerebral oxygen saturation value observed soon after right cannulation in both cases suggest an insufficient cerebral collateral flow compensation. The risk of ipsilateral watershed injury should be considered before cervical cannulation, notably in the context of sepsis and an evaluation of the cerebral collateral blood flow before and just after cannulation may be interesting in order to identify infants with higher risk of ipsilateral ischemic lesions.
