Surgical repair of a residual lesion of mixed-type total anomalous pulmonary venous connection using a vertical vein as a free graft: a case report

Abstract

BackgroundMixed-type total anomalous pulmonary venous connection is a rare condition in which the pulmonary veins possess multiple drainage sites. In the treatment of multiple lesions, it is sometimes necessary to treat only the main lesion first and repair additional residual lesions during follow-up.Case presentationWe report a case of additional repair of a remaining type Ia lesion in a 19-year-old woman with mixed-type total anomalous pulmonary venous connection who had previously been treated for a type IIa lesion alone. The vertical vein was used as a free graft in the surgery, and the reconstruction was successful without turbulence or kinking.ConclusionsOur results suggest that the use of the vertical vein as a free graft for the repair of residual type Ia lesions in adulthood allows reliable reconstruction regardless of the spatial relationship between the left atrial appendage and the left superior pulmonary vein.
