Letter:Is harmonic scalpel good for radial artery harvesting?

We read the original investigation “Comparison of ultrasonically activated scalpel and traditional technique in radial artery harvesting; an electron microscopic evaluation” by Dumantepe et al. (1) with interest published in May issue The Anatolian Journal of Cardiology 2011; 11: 250-6. In the research 40 patients undergoing coronary bypass with radial artery harvesting were divided into two groups based on the use of the ultrasonic cautery (UC) and the electrocautery (EC). The patients were divided into subgroups of two different storage, either at room temperature or normothermic organ bath.
