Detachable Embolization Coils Group
Patients who have an intervention for leak closure with detachable embolization coils leak closure with either detachable embolization coils, vascular plugs/CSO, or RFA: All patients were evaluated and followed with imaging, and per investigators' respective clinical judgement, then proceeded to have an intervention for leak closure with either detachable embolization coils, vascular plugs/CSO, or RFA.
Vascular Plugs/Septal Occluders Group
Patients who have an intervention for leak closure with vascular plugs/CSO leak closure with either detachable embolization coils, vascular plugs/CSO, or RFA: All patients were evaluated and followed with imaging, and per investigators' respective clinical judgement, then proceeded to have an intervention for leak closure with either detachable embolization coils, vascular plugs/CSO, or RFA.
RF Ablation Group
