The Swan Ganz pulmonary artery catheter is widely used in the intensive care unit. It allows the determination of important hemodynamic parameters. Among these, pulmonary artery occlusion pressure ("wedge" pressure) is often considered to reflect accurately left ventricular preload and pulmonary capillary hydrostatic pressure. However, many interferences may render data interpretation difficult, especially in patients undergoing mechanical ventilation. This article reviews some of these pitfalls.
We saw two infants with the unusual combination of oculomotor nerve palsy, facial capillary hemangioma, cerebellar hypoplasia, and apparent gaze palsy. Systematic imaging of children with congenital oculomotor nerve palsy may lead to the recognition of more associated neurologic abnormalities that are not clinically apparent, as was the case in our patients.
