Evaluation of the Effects of Ulnar Artery Flow and Allen's Test on Radial Artery Graft Preference

Ekin Ilkeli

Background: This study is to evaluate the efficacy of preoperative and postoperative ulnar arterial flows and Allen’s test in using radial artery graft. Materials and Methods: We retrospectively reviewed the prospectively collected data of 30 patients who underwent coronary surgery in a sıngle-center .Doppler ultrasonography and modified Bedford Allen’s test was performed on all patients before surgery. It was understood from the records that the ulnar artery flows in the postoperative period were controlled by Doppler ultrasonography at the 3rd and 6th months. Results: There was an increase in flow and velocity measurements in ulnar artery. The flow increased from 31 ± 21 ml/min to 46 ± 32 ml/min, and the speed increased from 56 ± 19 cm/sec to 78 ± 16 cm/sec. In the postoperative 3rd and 6th month Doppler USG, increased ulnar artery diameters and flows were found. Conclusion: Allen's test and ulnar flow measurements guide the use of radial grafts in coronary bypass operation
