[Intravascular hemolysis due to residual shunt after patch closure of VSD: a case report]

A patient with intravascular hemolysis due to residual shunt after patch closure of VSD was presented. The patient was 31-day-old female. She underwent VSD closure with Dacron patch 2 weeks after the initial operation (subclavian flap method) for coarctation concomitant with VSD. Soon after the operation, severe intravascular hemolysis and hemolytic anemia appeared. Conservative therapies were not effective, and her general condition got worse gradually. Forty days after closure of VSD, she underwent reoperation and the shunt was closed. Hemolysis disappeared dramatically. It was suggested that early reoperation was necessarily when severe intravascular hemolysis due to residual shunt after patch closure of VSD had persisted.
