Amplatzer Vascular Plug 4 Insertion for the Treatment of a Left Subclavian Artery Pseudoaneurysm.

We report the case of a 74-year-old male with an incidental finding of a pseudoaneurysm at the base of his neck arising from the left subclavian artery. Initial treatment with ultrasound-guided thrombin injection was unfortunately unsuccessful with early recanalization. An Amplatzer Vascular Plug 4 device was introduced into the neck of the pseudoaneurysm endovascularly with successful thrombosis and occlusion of the pseudoaneurysm.
