Özet: Purpose: The aim of this study is to evaluate the forearm artery circulation preoperatively to identify arterial dominance into the hand and to describe the effects of radial artery (RA) harvest on the forearm blood flow in the harvested forearm, postoperatively. Methods: Between January 2003 and January 2005, a total of 52 patients (40 male, 12 female) scheduled for RA harvest in CABG. Mean age was 56 ± 7 years. They were evaluated preoperatively and one year after RA harvest by color flow Doppler ultrasonography for forearm artery circulation in the harvested forearm. Results: In the evaluation of the ulnar artery (UA); the mean cross-sectional area was 5.3 mm2 preoperatively and significantly increased to 5.8 mm2 postoperatively (p=0.005). The mean peak systolic velocity in the UA significantly increased preoperatively to postoperatively, from 58.9 cm/sec to 73.9 cm/sec (p<0.001). Preoperatively the mean blood flow in the RA was 60.2 ml/min and in the UA was 60.4 ml/min and postoperatively in the UA significantly rose to 105 ml/min. After one year follow-up, the patients were not complaining of any ischemic symptoms except minimal paresthesia at the fingertips in 2 patients. Conclusion: The postoperative mean blood flow in the UA (105 ml/min), which increases to compensate the harvested RA, is lower than the preoperative total mean blood flow in the sum of the RA and the UA (120.6 ml/min), however the difference is not statistically significant. There was no ischemic complication of the hand. Blood flow to the hand will not be compromised by RA harvest and can be performed safely in selected patients. (Turkish J Vasc Surg 2005;14(2):7-12).
