[Architectonics of pulmonary vessels in pulmonary stenosis].
The authors aimed their work on the study of the architecture of pulmonary blood vessels and blood flow via pulmonary vascular network in patients with Fallot malformation. In 34 children with valvular stenosis of a. pulmonalis and in 12 children with Fallot tetralogy they analysed in detail their angiograms, paying attention to evaluation of the architecture of truncus pulmonalis and its branches, the discharging part of the right ventricle, and the state of the arterial phase of the pulmonary vascular network. On the basis of their results the authors explain the preferential blood distribution in Fallot's tetralogy by the displacement of the outflow part of the right ventricle to the right and by a greater amanation angle between the right branch of a.pulmonalis and its truncus. Better routing of blood into the left lung in patients with pulmonary valvular stenosis is according to the authors due to a greater emanation angle between the left branch of a.pulmonaris and its truncus. The authors analyse also the mechanism of formation of poststenotic dilatation of truncus pulmonaris and the left branch of a.pulmonaris in cases of valvular stenosis in infant age.
