Pulmonary vascular structure in patients dying after a Fontan procedure. The lung as a risk factor.

摘要: Pulmonary vascular structure was analysed in the lungs of 12 patients who had a Fontan repair, 11 whom died. Of eight with low pulmonary blood flow preoperatively, almost normal seven, but remaining patient many intra-acinar arteries contained organised occlusive thrombi. four an increased immediately before operation, there significant increase smooth muscle despite three having arterial band. The findings suggest that it is more difficult for to fulfil criteria and even when resistance less than 4 units/m2 may be abnormalities likely right atrial afterload prejudice outcome repair.
