Intra-arterial thrombolysis of central retinal artery occlusion following percutaneous atrial septal defect closure

Use of percutaneous devices for atrial septal defect (ASD) closure is growing, given the minimally invasive nature and the long-term durability of this approach. The reported rate of thrombus formation after catheter closure is 1.2%. Thrombotic risk varies according to closure device and Dacron-covered nitinol Amplatzer devices carry a 0-0.3% rate of thrombus formation; but central retinal artery occlusion (CRAO) is rarely implicated as an adverse event. Herein, we report the first successful intra-arterial thrombolytic treatment of CRAO developing after ASD closure via Amplatzer device.
