J. Maxwell Chamberlain Memorial paper: cardiovascularUse of the radial artery graft after transradial catheterization: is it suitable as a bypass conduit?
Section snippets
Patients
This was a retrospective cohort study. From January 1999 in our hospital, a total of 67 consecutive patients underwent elective isolated coronary artery bypass grafting using the RA. Patients with renal dysfunction were not included in this study because the use of the RA was avoided owing to the possibility for the need of it to make an arteriovenous shunt for hemodialysis therapy in the future. Of those patients, 22 patients underwent preoperative TR catheterization on the same side on which
Clinical outcome
Hospital death occurred in two patients in group 2 because of perioperative myocardial infarction, but the incidence of hospital death did not show a significant difference between the groups (p = 0.55). No other patients suffered any serious postoperative complications.
Angiographic results
The stenosis-free graft patency rates in groups 1 and 2 were 88% (16 of 18 patients) and 90% (38 of 42 patients) in the LITA, 77% (17 of 22 patients) and 98% (48 of 49 patients) in the RA, and 87% (13 of 15 patients) and 84% (21
Comment
This study demonstrated that preoperative TR catheterization deteriorated early graft patency and caused intimal hyperplasia in the RA, although it did not affect early clinical outcomes.
The use of the RA has been revived because of the availability of antispastic agents, as well as improvement of the harvesting technique [2]. This revival of RA use has made available an additional arterial conduit, which can be used in tandem with the LITA to achieve predominantly or totally arterial coronary
