Another Interesting Case
Incidental Left Subclavian Obstruction During LIMA Cannulation Managed with Peripheral Intervention
An 80-year-old male, post-CABG (2017), presented with complaints of exertional angina (CCS Class III).
Coronary angiography revealed patent grafts, including LIMA to LAD, SVG to OM, and SVG to PDA, suggesting good surgical outcomes.
However, during an attempt to cannulate the LIMA graft, the catheter could not be advanced through the left subclavian artery, raising suspicion of a proximal obstruction.
Further evaluation confirmed a significant lesion in the left subclavian artery, which was likely contributing to compromised flow dynamics despite patent grafts.
The patient was subsequently taken up for peripheral intervention. The lesion was successfully crossed and treated, resulting in restoration of adequate vessel patency and flow.
The final outcome was satisfactory, highlighting the importance of identifying and managing extra-coronary causes of angina in post-CABG patients.
