Coronary subclavian steal syndrome: non-invasive imaging and percutaneous repair.
Although coronary subclavian steal syndrome (CSSS) is relatively uncommon, it is a well documented cause of graft failure in patients having undergone coronary artery bypass grafting (CABG) using the left internal mammary artery (LIMA). Here we report a case of CSSS induced by restenosis of a left subclavian artery (SCA) origin stent, identified by increased velocities within the stent and an abnormal ipsilateral vertebral artery (VA) waveform on Duplex ultrasound imaging. This was successfully treated percutaneously by re-stenting, resulting in restoration of normal SCA waveforms and velocities, and normalization of the ipsilateral VA waveform.
