### Question: Can harvesting techniques modify postoperative results of the radial artery conduit?

### Context: 1: Inappropriate harvesting of arterial conduits can lead to severe postoperative complications. We analyzed clinical and functional results of patients undergoing radial artery (RA) harvesting by means of three techniques.
2: From January 2001 to January 2004 188 patients undergoing coronary artery bypass graft with RA were divided into three groups: harmonic scalpel was employed in 61 (RA1), electrocautery in 63 (RA2), Potts-scissors and clips in 64 (RA3) patients. Harvesting time, local complications, number of clips employed, graft flowmetry, postoperative troponin I, incidence of re-exploration for bleeding due to the graft were analyzed.
3: RA1 and RA2 showed a lower harvesting time (RA1 16.2 +/- 8.4 vs RA3 41.4 +/- 7.7 min, p = 0.0001; RA2 21.1 +/- 10.4 min, p = 0.001). Postoperative hand paresthesia was detected in RA1 (5/61; 8.2%) and RA2 (5/63; 7.9%), but not in RA3 (p = 0.048 and p = 0.05, respectively). More clips were necessary in RA3 compared to RA2 (p = 0.04) or RA1 (p = 0.0001 vs RA3; p = 0.001 vs RA2). RA1 showed significant higher values of maximum flow (RA1 59.4 +/- 37.5 vs RA2 22.1 +/- 7.7 ml/min, p = 0.0001; vs RA3 31.3 +/- 12.0 ml/min, p = 0.001), mean flow (RA1 23.4 +/- 17.3 vs RA2 10.2 +/- 5.7 mi/min, p = 0.001; vs RA3 11.6 +/- 8.9 ml/min, p = 0.001), minimum flow (RA1 11.6 +/- 6.5 vs RA2 4.2 +/- 3.7 ml/min, p = 0.01; vs RA3 4.7 +/- 3.3, p = 0.03), and pulsatility index (RA1 0.9 +/- 0.8 vs RA2 2.1 +/- 1.3, p = 0.03; vs RA3 1.7 +/- 2.1, p = 0.04). Troponin I was significantly lower in RA1, compared to RA2 and RA3 at 12 hours (p = 0.01 and p = 0.03, respectively) and 24 hours (p = 0.05 and p = 0.045, respectively). No RA1 patient underwent re-exploration for bleeding compared to RA2 (p = 0.011) and RA3 (p = 0.02).


###Response: RA harvesting with ultrasounds is fast, determines high flowmetry values, low enzyme release and rarely causes local complications.
