Abstract

BACKGROUND: Radial artery harvest for coronary artery surgery leads to chronically elevated blood flow in the remaining ulnar artery. This study examined the ulnar artery for evidence of increased atherosclerosis compared with the contralateral ulnar artery where the radial artery had not been harvested. METHODS: Patients were enrolled at least seven years after unilateral radial artery harvest. Anatomical and flow data were acquired using a high-frequency ultrasound probe. Maximal forearm blood flow was measured after repeated hand grip with concurrent brachial artery occlusion to induce forearm ischemia. RESULTS: Eighty five patients, 71 males at age 71 +/- 9 years (43 to 88) were assessed..
