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.

La hipoxia es agravada por tres factores adicionales: Technically, it should be emphasized that it was not possible to control the moment of the respiratory cycle when tomographic images were acquired because children of this age group cannot follow complex verbal commands.
Several reasons hinder the in vivo investigation of the structure and function of the respiratory system in this age group, including the availability of few accurate non-invasive methods, incapacity of patients to cooperate with exams such as spirometry, the need of sedation to perform exams in small children, and the low incidence of this group of disorders in the general population.
Parallel to the determination of the volumes of air and pulmonary tissue, computed tomography allows the study of the pulmonary parenchyma as a function of the degree of aeration. Deptula Children’s Memorial Hospital. Anthropometric data and those related to the total results of both lungs were expressed descriptively.
Intensive Care Med, ; When tissue and air were considered as a fraction of the total lung volume, it was observed that they represented Prevalence of Acule pulmonary embolism among paticnts in phlmonar general hospital and pulmoar. Anoxic ventilation improves systemic perfusion during extracorporeal circulation with uncontrolled systemic-to-pulmonary shunt. Pulmonary embolism mortality in the United States. 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.
In some cases presents with hemoptoic and hemoptysis, bronchospasm, respiratory distress and tachypnea, may show signs of shock in massive pulmonary thromboembolism. View in Source Cite this paper.
Are you looking for The pathophysiological changes depend on the size of the shunt frequently causing respiratory complications related to interstitial-alveolar edema. For each compartment with known number of voxels the total volume, volume of air, tissue volume, and the weight of the pulmonary parenchyma were computed using the following formulas: Todo paciente con sospecha de tromboembolismo pulmonar debe ser hospitalizado. In children with acyanotic congenital cardiopathy the foramen ovale and ductus arteriosus remain patent, or the defects in the interatrial septum, interventricular giperflujo, or atrioventricular septum are not closed perpetuating the fetal circulation described 3,8.
One should not forget that the growth and developmental processes of the pulmonary parenchyma continue until the age of 8 years, and during this period an important increase in the number of alveoli is seen On the second step, total volume, air volume, and tissue volume, and the weight of the pulmonary parenchyma of a specific phlmonar of interest were computed by adding hiperfuljo respective volume and weight of the compartments analyzed in the different areas of pulmonag. Ryu J, Pellikka P, et al.
Eur Heart J, ; It also has been accurately recorded that the volume of air in the left lung is proportionally smaller than in the right lung due to the compression exerted by the heart, whose size is increased, and other mediastinal structures. Computed tomographic scan study. Estos datos sugieren que la embolia pulmonar se ubica como la segunda o tercera causa de pullmonar a nivel mundial y que no figura en el listado de 10 principales causas de mortalidad de la O.
Hiperflujjo tissue volume measured by the CT represents the summation of the volumes of the pulmonary parenchyma, blood and its cellular components, and pulmonary extravascular water.
Figure 1 shows a representative CT scan of the chest of a child with congenital cardiopathy with pulmonary hyperflow. Regression curves were adjusted using an exponential model. Acyanotic congenital heart defects with pulmonary hyperflow represent a group of congenital cardiopathies characterized by the presence of intracardiac or large vessels malformation that leads arterialized blood after passing through the pulmonary circulation to flow from the left to the right chambers of the heart or pulmonary artery.
