OBJECTIVE: Endoscopic radial artery (RA) harvesting performed concurrently with internal mammary artery (IMA) takedown and endoscopic saphenous vein (SV) harvesting creates a crowded and inefficient operating room environment. We assessed the effect of a presternotomy RA harvest strategy on surgery time and costs.METHODS: A total of 41 patients underwent elective, first-time, isolated multivessel on-pump coronary artery bypass grafting including an IMA, RA, and SV graft. The first 20 patients (Phase I) underwent endoscopic RA harvesting concurrently with IMA takedown and endoscopic SV harvesting after sternotomy, requiring two sets of endoscopic harvesting equipment per case, each used by a separate individual. The final 21 patients (Phase II) underwent endoscopic RA harvesting during anesthesia line placement, completing the procedure before sternotomy, thus requiring only one set of endoscopic harvesting equipment reused by a single individual.RESULTS: There were no differences in baseline patient characteristics, number of bypasses, duration of SV or RA harvest time, or duration of cardiopulmonary bypass or cross-clamp time between the two groups. Total surgery time was reduced by 32 minutes in Phase II (P = 0.044). Relative to a total hospital direct cost of 100.00 units, total surgery costs were reduced from 29.33 units in Phase I to 25.62 units in Phase II (P = 0.001). No anesthesia- or RA harvest-related complications occurred in either group.CONCLUSIONS: Endoscopic RA harvesting can be safely performed during anesthesia line placement prior to sternotomy. Our simple but innovative strategy improves intraoperative workflow, reduces the time and cost of surgery, and advances the delivery of high-quality patient care.
