Reduction in wound morbidity rates following endoscopic saphenous vein harvest.

To determine whether less-invasive saphenous vein harvest reduces morbidity in patients undergoing infrainguinal bypass, we retrospectively compared 61 patients undergoing endoscopic harvest (ENDO) with 49 patients undergoing conventional harvest (OPEN) over the past 13 months. Patients were classified as potential short-stay if adjunctive suprainguinal inflow procedures or foot amputations were not required and the patient was ambulatory prior to elective operation. Mean endoscopic harvest time was 50+/-18 (range 25-90) min, and no more than three 5-cm incisions were required in 87% of cases. Szilagyi class II or III wound complications occurred after 1 of the 61 (2%) ENDO procedures and 7 of the 49 (14%) OPEN (p < 0.01), and any complication occurred in 13 (21%) vs. 25 (51%) of ENDO and OPEN procedures, respectively (p < 0.002). Mean postoperative length of stay was significantly shorter in the 24 short-stay ENDO (4.0+/-2.4 days) vs. 25 short-stay OPEN (6.0+/-3.2 days) patients (p < 0.02). Thirty-day patency rates between the two groups were not different. Endoscopic saphenous vein harvest is associated with a reduced incidence of serious wound complications and, in selected patients, shortened postoperative hospital stay.
