Background:
It has been demonstrated that bilateral use of internal thoracic arteries (ITAs) confers better long-term results in patients than does unilateral use. However, routine use of bilateral ITAs has usually been avoided.
Methods:
Since 1997, we have used bilateral ITAs extensively for patients who required multivessel bypasses. Recently, 243 consecutive patients, including 127 diabetic patients, were reviewed.
Results:
Every patient received at least one ITA graft, and 200 patients (82%) received bilateral ITAs. The majority (93%) of ITA grafts were used as in situ grafts. The hospital mortality rate was 0.41%, and deep sternal infections were observed in 5 patients (2.0%). There was no difference in the incidence of chest wound infection between the group treated with bilateral ITA grafting and that treated by unilateral ITA grafting.
Conclusions:
These observations suggest that ITAs can be used bilaterally for treatment in the majority of patients who require multivessel bypass, with low mortality and morbidity.
