Great saphenous vein harvest is associated with a significant risk of impaired wound healing. The purpose of this study was to determine efficacy of one system designed for minimally invasive vein harvest (MIVH) and to assess postoperative and mid-term wound-healing disturbances. From February 2004 to June 2005, great saphenous harvest for coronary artery bypass grafting (CABG) was performed in a group of 120 consecutive patients employing the VEGA system (B/Braun-Aesculap, Tuttlingen, Germany). Patients were evaluated on 7th postoperative day, at the 3-month and 1-year follow-up for wound healing disturbances, residual leg edema, and saphenous neuropathy. The mean age was 67.3 years, male patients dominated (70%), and the leading procedure was CABG (83%). The mean number of harvested venous grafts was 1.9 +/- 1.2 and the mean number of skin incisions was 3.7 +/- 2.2. The mean total vein harvesting time was 40.2 +/- 16.8 minutes. Satisfactory healing was achieved in 98% patients on 7th postoperative day and at the 3-month follow-up all wounds were completely healed. Saphenous neuralgia remained a significant cause of morbidity, although its incidence decreased from 25% presented on 7th postoperative day to 8% presented at 1-year follow-up. Likewise, the incidence of leg edema decreased from 34% on the 7th postoperative day to 7% at 1-year follow-up. Minimally invasive vein harvest is a safe method associated with a significant reduction of wound disturbances. The VEGA system appears to be suitable and effective equipment for MIVH. Nevertheless, residual edema and mainly saphenous neuropathy represent a relatively frequent cause of patient morbidity at the postoperative and mid-term follow-up.
