Endovascular intervention is a commonly accepted form of treatment in patie
nts with subclavian artery stenosis. Complications will undoubtedly occur a
s the utility of catheter-based intervention continues to rise. We report t
wo cases of subclavian artery disruption as a result of endovascular interv
ention. One patient had contrast extravasation after the deployment of a ba
lloon-expandable stent in a stenotic subclavian artery, and the arterial in
jury was successfully treated with balloon tamponade. A second patient had
a large subclavian pseudoaneurysm 4 months after a balloon-expandable stent
placement. Successful repair was achieved in this patient by means of arte
rial reconstruction with a prosthetic bypass graft. These cases illustrate
different therapeutic methods of treating subclavian artery rupture due to
endovascular intervention.
