Sequential grafting of the right gastroepiploic artery in coronary artery bypass surgery.
BACKGROUND
Only a few studies have been done on sequential grafting using the right gastroepiploic artery (GEA).


METHODS
Forty patients (35 males, ages 36 to 74 years) who underwent sequential grafting of the GEA were reviewed. Angiography of the GEA was performed preoperatively in all patients. GEAs with a luminal diameter greater than 2 mm at the presumptive distal anastomosis on the angiogram were used. The dissected GEA was led into the pericardial cavity through the antegastric route. We used GEAs to graft 89 branches (2.2 per patient) in the inferoposterior region.


RESULTS
In 24 patients who had angiographic examinations, all the GEAs were patent, although luminal narrowing was noted in the segment between the two anastomoses in 3 patients. Eight-year actuarial survival was 92.5% and the cardiac-related event-free rate was 95%.


CONCLUSIONS
Sequential grafting of the GEA can be performed effectively in selected patients. Performing preoperative angiography to assess the size of the GEA for sequential grafting is strongly recommended.
