Intraoperative graft flow, measured
by a BF1001 CardioMed Flowmeter and the postoperative graft diameter
of the left internal thoracic artery, measured by coronary angiogram
were compared in the semi-skeletonization method group (23 patients)
and the skeletonization method group (29 patients). There was
no significant difference between 2 groups in terms of age, gender,
body surface area, diabetes mellitus, LAD lesion, preoperative
ejection fraction, operation time, cardiopulmonary bypass time
and aortic cross-clamp time. Graft flow was significantly larger
in the skeletonization method group than in the semi-skeletonization
method group (50.4±21.7ml/min vs 36.9±12.8ml/min, p=0.019).
However graft diameter did not differ significantly between the
2 methods (2.46±0.44mm in the skeletonization method group and
2.38±0.42mm in the semi-skeletonization method, p=0.991).
These results suggested that left internal thoracic artery could
be used longer by either 2 methods than by pedicled harvesting
technique, however skeletonization method caused less spasm during
graft harvesting than the semi-skeletonization method.
