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.

The objective of this study was to quantify the volumes of air and tissue, as well as the distribution of pulmonary aeration in this population. Esto produce a su vez tres consecuencias: The clinical course of pulmonary embolism: The attenuation coefficient CT coefficient of 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.

In normal conditions, after birth with the occlusion of the umbilical cord and pulmonary expansion, vasodilation and reduction in vascular resistance is seen in the pulmonary circulation with the consequent increase in pulmonary blood hiperfflujo and in venous pulmonary pressure.

Obstruction of the pulmonary artery or one of its branches gets incremented the resistance and the pulmonary arterial pressure, and consequently leads to increased right ventricular afterload.

Stocks J, Quanjer PH – Reference values for residual volume, functional residual capacity and total lung capacity. Pulmonary aeration is reduced in the left lung due to the compression of the lung by the heart.

DeptulaThomas R. Using a combination of chest CT and helium dilution technique, Gattinoni et al. The absence of a control group is another important factor, since one cannot justify performing Pulmonxr scans in children without cardiopulmonary disorders.


La base del tratamiento lo constituye el uso de anticoagulantes.

Mull RT – Mass estimates by computed tomography: In adult patients in different clinical conditions and in experimentation animals helical computed tomography allows the quantitative and qualitative evaluation of pulmonary changes using volumes and X-ray attenuation by the pulmonary parenchyma 4,5. Continuous axial images were reconstructed from the volumetric data using the reconstruction algorithm of the CT equipment, with 5-mm width.

Table I shows individual anthropometric data and the diagnosis of the patients included in the study.

This papcr prcscnts a literature review that huperflujo the management and treatment in a paticnt with pulmonary thromboembolism. Exercise performance is unaffected by age at repair. Lanotte et al Efficace of norcpinephrine thcrapy in shock eomplicating acute pulmonary embolism.

A considerable percentage of this population undergoes surgical correction of cardiac defects in the first two years of life to avoid the harmful consequences of persistent hyperflow on the pulmonary circulation. Figure 1 shows a representative CT hiprflujo of the chest of a child with congenital cardiopathy with pulmonary hyperflow.


There were no indices of oxygenator failure noted within the time frame of support. When the pulmonary parenchyma of the children was evaluated according to the degree of aeration, it was observed that non-aerated pulmonary parenchyma represented 9.


Bryan Terry 2 Estimated H-index: Resp Med ; In some cases presents with hemoptoic and hemoptysis, bronchospasm, respiratory distress and tachypnea, may show signs of shock in massive pulmonary thromboembolism. Julio de Aceptado: In general, one third of the total blood volume of a child flows to the left atrium through the foramen ovale, while the remaining two thirds flow to the pulmonary artery.

Intensive Care Med, ; In some patients with acute respiratory distress syndrome, Malbouisson et al. The increase in partial pressure of oxygen leads to vasoconstriction of the ductus arteriosus and eventual closure in the first three to four weeks of life. The pulmonary volume of air on the right was On the second step, total pulmnoar, air volume, hiperfluoj tissue volume, and the weight of the pulmonary parenchyma of a specific area of interest were computed by adding the respective volume hoperflujo weight of the compartments analyzed in the different areas of interest.

Inclusion criteria were as follows: The patient had a successful support run without complications related to cardiopulmonary support. On the other hand, despite normal peripheral saturation of hemoglobin, a considerable fraction of the pulmonary parenchyma was poorly aerated. Carson JL, et al. La hipoxia es agravada por tres factores adicionales: Computed tomographic scan study. Todo paciente con hilerflujo de tromboembolismo pulmonar debe ser hospitalizado.
