ObjectiveThe use of radial artery conduits in coronary artery bypass grafting (CABG) surgery is associated with improved long-term patency and patient survival rates as compared with saphenous vein conduits. Despite increasing popularity, relative incidence of local harvest-site complications and subjective perception of adverse long-term sequelae remain poorly described.MethodsTo allow for direct comparison, we investigated a consecutive series of patients in whom both the radial artery and the saphenous vein had been harvested for isolated CABG during a 36-month period. Patients were identified from a prospective database that collects baseline clinical information. The patients' own perceptions were assessed by a standardized direct telephone survey regarding any persistent functional impairment from their arm and leg operation sites.ResultsOut of 1756 CABG patients during the study period, 168 (10%) were eligible (78% men, median age: 60.1 ± 9.6 years, range: 29.6-82.4 years). Of these, 123 (73%) could be contacted and interviewed at a median follow-up time of 2.5 ± 0.9 years. Surgical wound complications at harvest sites (arms and legs) had occurred in 3% and 12%, respectively, and persistent symptoms (arms and legs) were self-reported as follows: chronic pain (5% and 8%), numbness (32% and 34%) and paresthesia/dysesthesia (14% and 7%). Overall, 39% of the patients reported persistent discomfort at the arm and 39% at the leg. Both sites were simultaneously affected in 21% (P = n.s., paired testing). Logistic regression modeling showed that patients with adverse long-term sequelae were younger (P < 0.005), had a higher body mass index (P < 0.05) and a lower EuroSCORE (P < 0.001) at the time of operation (EuroSCORE, European System for Cardiac Operative Risk Evaluation). Perioperative wound complications, however, did not predict persistence of symptoms.ConclusionsPersistent harvest-site discomfort occurs with astonishing frequency after CABG surgery and affects arms and legs equally. Although usually considered a minor complication, long-term limitation to quality of life may be substantial, particularly in younger and relatively healthy patients. Thus, harvest-site discomfort clearly belongs to the list of possible post-CABG complications of which patients need to be aware.Copyright © 2010 European Association for Cardio-Thoracic Surgery.
