  Fig. 1 Coil-in-plug method. (a) Before implantation, the Amplatzer vascular plug I was unfolded from the loader, and a 2.2-F microcatheter was inserted passing through the plug using a 0.016-in guidewire. (b) The plug was stored in the loader in a heparinized saline solution to prevent air from entering the plug. (c) The plug was placed in the left subclavian artery, and the stent graft was delivered to the aortic arch. (d) After deploying the stent graft, a microcatheter was placed through the plug and was embolized between the stent graft and the plug as well as inside the plug.
