La disfunción respiratoria es frecuente en niños con cardiopatías congénitas acianóticas con hiperflujo pulmonar (CCAHP), sin embargo, se conoce muy poco . Introduccion: tradicionalmente los lactantes portadores de cardiopatias con hiperflujo pulmonar, bajo peso e infecciones respiratorias, eran sometidos a cirugia. Hiperflujo e hipertensión venocapilar pulmonar. from publication: “Criss – cross with atrioventricular concordance and ventriculoarterial discordance” clinical.

A technique for performing antegrade selective cerebral perfusion without interruption of forward flow or cannula relocation for pediatric aortic arch reconstruction. Regression curves were adjusted using an exponential model. In children with acyanotic congenital cardiopathy the foramen ovale and ductus arteriosus remain patent, or the defects in the interatrial septum, interventricular septum, or atrioventricular septum are not hipeerflujo perpetuating the fetal circulation described 3,8.
This compartment of the pulmonary parenchyma is probably increased due to interstitial edema and increase in the volume of blood in pulmonary capillaries, but maintaining the aeration of the alveoli and small airways.
Anoxic ventilation improves systemic perfusion during extracorporeal circulation with uncontrolled systemic-to-pulmonary shunt. Diego Abdala 3 Estimated H-index: After placement of a new systemic to pulmonary shunt, the patient was removed from support and the oxygenator drained of residual blood. The normal distribution of all parameters measured in this study was tested by the Kolmogorov-Smirnov test.
This oxygenator is designed exclusively for neonates and infants and has the smallest priming volume of any clinically available oxygenator.
Intensive Care Med, ; Nijkeuter M, Sohnc M, et al. Pulmonary embolism is thc obstruction of thc pulmonary artery or one of its branches, by a thrombus sccondary to a deep vein thrombosis.
Tratamos al paciente exitosamente con uso de heparinas de bajo hiperfluo molecular enoxiparina 60 mg S. As mentioned before, studies investigating the pulmonary parenchyma of children without cardiorespiratory diseases with computed tomography are lacking; however, Vieira et al.
Since patients were unable to follow commands for apnea, the test was done during spontaneous breathing after the children get used to the environment. The absence of a control group is another important factor, since one cannot justify performing CT scans in children without cardiopulmonary disorders.
To conclude, children with acyanotic congenital cardiopathy with pulmonary hyperflow have an increase in the volume of pulmonary tissue greater than expected in normal conditions. Hiperflumo axial images were reconstructed from the volumetric data using the reconstruction algorithm of the CT equipment, with 5-mm width.
Respiratory dysfunction is common in children with acyanotic congenital heart defects ACHD with pulmonary hyperflow; however, little is known about the pulmonary structure of those patients.

Patients had a mean age of 20 months and weight of 9. Crit Care Med ; Using this analysis, it is possible to compute the volume of air and tissue present in the lung.
Am J Cardiol, ; Exposures were done at kV and mAs, using a one-second rotation time, mm collimation, and pitch of one. Mull RT – Mass estimates by computed tomography: View in Source Cite this paper. Eur Heart J, ; Paired Student t test or Wilcoxon test were used to compare the left and right lungs. There were no indices of oxygenator failure noted within the time frame of support. Fogg Children’s Memorial Hospital.
Hiperrlujo the pulmonary parenchyma was analyzed in relation to the distribution of aeration, it was observed that the non-aerated pulmonary parenchyma represented 9. Early Hum Dev, ; The right panel of figure 4 shows that the fraction of pulmonary parenchyma classified according to the degree of aeration in relation to the total weight of the parenchyma are compared between hiperfluujo right and left lungs.
Physiologically, the development of clinical manifestations depends on the magnitude of the flow through the right-left communication and it is essentially translated by the presence of pulmonary congestion of varying degrees and cardiomegaly 1.

In normal conditions, after birth with the occlusion of the umbilical cord and pulmonary expansion, vasodilation hipeflujo reduction in vascular resistance is seen in the pulmonary circulation with the consequent increase in pulmonary blood flow and in venous pulmonary pressure. The attenuation coefficient CT coefficient hipeflujo each voxel is defined as the attenuation coefficient of X-rays crossing the study material minus the water attenuation coefficient divided by the water attenuation coefficient and expressed in Hounsfield units HU.
Pulmonary embolism mortality in the United States. The patient had a successful support run without complications related to cardiopulmonary support.
Since the weight of the patients varied the data on the volumes of pulmonary air and tissue and the weight of pulmonary compartments hiperfluio to the degree of aeration pulnonar presented as a fraction of the total volume and weight, respectively.
After approval by the Ethics Committee of the institution and signing of an informed consent, seven children with ACHD with pulmonary hyperflow underwent computed tomographies of the chest. Figure 1 shows a representative CT scan of the chest of a child with congenital cardiopathy with pulmonary hyperflow.
