Abstract
At present more and more surgeons are using the radial artery as a graft for coronary bypass. The statistics until now show that the patency of radial grafts exceeds that of the venous grafts used up to the present.
In our department we used radial artery for coronary bypass in 515 patients between January1990 and December 2000. The radial artery harvesting with minimally invasive technique developed by us was applied in 50 of these patients while the rest were performed with the traditional method. No ischemic complications occurred in forearm or hand following either of the methods.
One year after the operation we carried out control examinations on 197 consecutive patients. Our surveys showed that following the traditional technique of radial artery harvesting neurological complications (temporary dysaesthesia) occurred in 16.5% of the patients. After the minimally Invasive procedure, temporary dysaesthesia occurred in one case (2%). These complaints ceased within 1–12 months (an average of 3.8 months). Definitive neurological complications did not occur in any of the patients.
In summation, we experienced that both operating techniques can be safely applied. The proportion of temporary neurological complications is higher following the traditional procedure, therefore, further development and application of the minimally invasive procedure should be considered.
