40-year-old man with suspected arterial injury after central venous catheter insertion. (a) CT angiogram(axial) of the neck showed contrast extravasation(arrow) at the junction between the right subclavian artery and internal mammary artery.

The endovascular approach to repair the arterial injury was chosen due to difficult surgical access [Figure 1a-c].

DSA showed contrast extravasation at the junction between the right subclavian artery and the internal mammary artery [Figure 2a]. Post embolization DSA of the right internal mammary artery showed no distal flow but persistent contrast extravasation from the proximal internal mammary artery [Figure 2b].

The proximal end of the stent was deployed distal to the origin of the right subclavian artery while the distal end was deployed distal to the origin of the right thyrocervical trunk [Figure 3a]. Mild contrast extravasation was noted after the stent deployment and balloon angioplasty was performed using a 10 mm Mustang balloon (Boston Scientific, Marlborough, Massachusetts) [Figure 3b-c]. Post-procedure DSA showed no contrast extravasation at the right subclavian artery [Figure 3d].
