Abstract/OtherAbstract:
More than 1,100 patients underwent a systemic-pulmonary arterial shunt operation at the Children's Memorial Hospital, Chicago, from 1946 to 1974. Of these patients, 294 were studied to assess the presence of pulmonary vascular disease and the time of its occurrence after surgery. They were selected either because lung tissue was available for histologic grading of pulmonary vascular disease (114 patients) or because hemodynamic studies were performed after the shunt operation (180 patients). The shunts, all patent at the time of the study, ranged in duration from 1 month to 23 years. After a subclavan-pulmonary arterial shunt (75 patients) there was little evidence of advatients) pulmonary vascular disease in either histologic C2 of 25 patients) or hemodynamic (1 of 50 patients) studies. After an aortic-pulmonary arterial shunt (44 Waterston, 175 Potts) there was small likelikhood of advanced pulmonary vascular disease with a shunt duration of less than 5 years (1 of 35 histologic, 0 of 27 hemodynamic studies). With a shunt duration of more than 5 years the incidence of advanced pulmonary vascular disease increased significantly (15 of 54 histologic, 17 of 103 hemodynamic studies). A mean pulmonary arterial pressure of 50 mm Hg or greater strongly suggests the presence of advanced pulmonary vascular disease. When a systemic-pulmonary arterial shunt has provided effective palliation with decreased pulmonary pressure there is small likelihood that advanced pulmonary vascular disease will develop, even with a long shunt duration of 20 to 25 years.
