Fig 1 The radial artery was selected as the inflow artery in patients with (1) risk of steal syndrome and (2) a ≥1.5-mm-diameter proximal radial artery. The risk of steal syndrome was estimated if radial artery or ulnar artery was severe stenosis or occlusion before arteriovenous graft (AVG). A, If the proximal radial artery was <1.5 mm, (B) the brachial artery was selected.

Fig 2 Primary and secondary patency after arteriovenous graft (AVG). The 1-year primary patency rate was 32.4%, and the secondary patency rate was 83.9% (P < .001). SE, Standard error.

Fig 3 Primary patency of the radial and brachial groups. The 1-year primary patency rate was 53.8% in the radial artery group vs 24.4% in the brachial artery group (P = .032). SE, Standard error.

Fig 4 Subanalysis of primary patency. In the 5-mm straight group, primary patency in radial artery group was significantly higher than that in brachial artery group (log-rank test, P = .018). In the 4- to 6-mm tapered group, primary patency was not statistically different between radial artery group and brachial artery group (P = .931). The 6-mm graft was not used in the radial group. Interaction analysis demonstrated that graft type (4- to 6-mm tapered vs 5-mm straight) did not have a significantly different unadjusted hazard ratio (HR) for primary patency between the radial inflow group and the brachial inflow group (P = .13 for interaction). SE, Standard error. Journal of Vascular Surgery 2016 64, 395-401DOI: (10.1016/j.jvs.2016.02.049) Copyright © 2016 Society for Vascular Surgery Terms and Conditions
