Long-term arm morbidity after radial artery harvesting for coronary bypass operation.
BACKGROUND
The use of the radial artery (RA) in coronary bypass operations has become increasingly popular in recent years, but there is almost no documentation regarding the midterm and long-term arm complications.


METHODS
Between January 1 and December 31, 1998, 109 patients underwent operations for myocardial revascularization employing a pedicled RA as 1 of the coronary grafts. The patients were surveyed for subjective arm morbidities at 2 times during their follow-up: short term (mean, 7 months postoperatively; range, 0.3-14 months) and long term (mean, 49 months postoperatively; range, 46-57 months).


RESULTS
At the short-term follow-up, 33 (33.3%) of the patients had some complaints regarding the arm that was operated on, with 4 (4%) of the patients reporting arm disability with complaints that focused on pain (11, 11%), numbness (15, 15%), and parasthesias (12, 12%). At the longterm follow-up, only 9 patients (10.5%) still experienced some sort of inconvenience with the arm that was operated on, with 1 case of functional disability, 4 complaints (4.6%) of residual parasthesias, and 1 report (2.3%) each of pain or numbness. All but 2 of the patients with complaints at the short-term follow-up reported amelioration of symptoms at the long-term follow-up.


CONCLUSIONS
It appears that severe arm disability early after RA harvesting is likely to dissolve with time. Our favorable late follow-up results support the continuation of the employment of the RA as a conduit for coronary artery bypass grafting operations.
