Abstract
The purpose of this study was to propose a safe, stepwise, testing system to select radial arteries that are suitable for conduits on the basis of their morphologies and characteristics of the collateral circulation. Before operation, 113 patients underwent the modified Allen test, Doppler ultrasonography, and pulse oximetry testing. Morphologic criteria used for radial artery exclusion were small size of radial or ulnar artery (< 2 mm in inner diameter), diffuse calcifications, and congenital anomalies of forearm arteries. Collateral circulation was interpreted as insufficient if the reverse flow in the anatomic snuffbox was absent or if the increase of the ulnar peak systolic flow velocity was less than 20%. A positive modified Allen test was found in 10.6% of patients. As assessed by Doppler ultrasonography, 27 patients (23.9%) were not candidates for radial artery harvesting according to morphologic and functional abnormalities of forearm and hand circulation. Pulse oximetry test results were abnormal in 6.2%. After a follow-up period of 8.9 +/- 1.8 months, 23 patients (29.1% of operated patients) were controlled for Doppler ultrasonographic changes in the ulnar artery. The mean peak systolic flow velocity was significantly...Continue Reading
