Can an early peri-anastomotic LITA stenosis be reversible?

Peri-anastomotic graft stenosis is a possible complication of coronary artery bypass graft operations. Early failure of myocardial revascularization may result from graft stenosis with inherent difficulties in perioperative diagnosis and subsequent management. We report the case of a 58-year-old man who experienced early preanastomotic left internal thoracic artery bypass stenosis that progressively resolved during a 2-year period without reoperation or interventional angioplasty. Although the mechanisms underlying graft stenosis remain unclear, this case emphasizes the role of repeated coronary angiography in the choice of treatment.
