Amplatzer Duct Occluder for treatment of displaced PDA coil induced late haemolysis

A 4-year-old child who underwent patent ductus arteriosus (PDA) coil closure for 3 mm PDA (figure 1A) with 052'' cook detachable coil, presented with the features of severe haemolytic anemia 4 months after PDA coil closure. Control angiography performed immediately after the coil deployment and control echocardiography performed 24 h after the procedure showed no residual shunt. A routine follow-up after 3 weeks postprocedure also revealed no residual shunt. No further follow-up was made. The cause for haemolytic anaemia was evaluated in detail and confirmed as residual PDA shunt, likely caused by the displacement of the coil from its initial deployed site. The removal of the already deployed coil was not advised, anticipating vascular damage and possible embolisation. An attempt to close the residual shunt by inserting two intertwined 038'' coils was performed but failed (figure 1B). Later, the residual PDA was successfully closed with 8/6 Amplatzer Duct Occluder...
