Insights
Severe haemolysis developed after transcatheter closure of patent arterial duct. Surgical removal of an extruded coil resolved the haemolysis, indicating a mechanical cause.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Medical Device Technology
Background:
- Transcatheter closure is a common method for treating patent arterial duct (PAD).
- Complications, though rare, can occur following device implantation.
Observation:
- A patient developed severe haemolysis one day after successful transcatheter PAD closure.
- Initial aortography and echocardiography showed no residual shunt.
Findings:
- A subsequent aortography revealed coil extrusion into the aorta as the cause of haemolysis.
- Surgical removal of the extruded coil segment was performed.
Implications:
- This case highlights a rare mechanical complication of transcatheter PAD closure.
- Prompt diagnosis and surgical intervention can effectively manage coil extrusion and associated haemolysis.
Abstract:
We report a development of severe haemolysis after complete transcatheter closure of patent arterial duct. Aortography and echocardiography revealed no signs of residual shunt. Haemolysis occurred a day after the implantation. Aortography was performed and the extrusion of coil in aorta was evident. The extruded part of the coil was surgically removed. No signs of haemolysis remained.
