Abstract

Background: Selected patients, presenting for reoperative coronary surgery with patent internal thoracic arteries (ITAs), may benefit from techniques to salvage and reuse these ITA grafts. We have termed this practice the recycling of ITAs. The purpose of this study is to report our short-term and midterm results using various recycling techniques.

Methods: Between April 1996 and February 2009, 60 patients underwent ITA recycling at our institution. Information regarding survival and cardiac events was obtained from a prospectively maintained, institutional database. Survival and freedom from major adverse cardiac events were calculated using Kaplan-Meier analysis. Mean follow-up duration was 60 ± 36 months.

Results: Mean age was 64 ± 9 years and the mean time to reoperation was 117 ± 68 months. The patent ITA served as an inflow for a composite Y graft in 39 patients and was distally reimplanted on the same coronary vessel in 9 patients. A combination of these two techniques was used in 8 patients. Other techniques were used in the remaining 4 patients. Freedom from cardiac death was 93% ± 7% and 85% ± 9% at 1 and 5 years and freedom from major adverse cardiac events was 93% ± 7% and 81% ± 11% at 1 and 5 years, respectively.

Conclusions: Recycling of ITA grafts during reoperative coronary artery bypass grafting is safe and feasible in selected patients. These techniques can be useful in selected young patients to avoid saphenous vein graft or in patients with a lack of graft conduits.
