Section snippets
Material and Methods
The study protocol was reviewed by the Institutional Review Board and approved as a minimal risk retrospective study (approval number: H-1601-064-734) that did not require individual consent based on the institutional guidelines for waiving consent.
Clinical Outcomes
Operative mortality was 1.0% (1 of 103) in group NT and 0.4% (1 of 265) in group MM (p = 0.487). There were no statistically significant differences in operative mortality and postoperative complications between the two groups before and after propensity score matching (Table 3). Leg wound complications in the SV harvesting site developed in 5 patients (group NT, 2.9% [3 of 103] versus group MM, 0.8% [2 of 265], p = 0.136). Of 366 surviving patients, a Jackson-Pratt drain was inserted in the SV
Comment
The present study demonstrated three main findings. First, the 1-year patency rate of SV grafts harvested with a “no-touch” technique further improved the early and 1-year patency of SV composite grafts. Second, the majority of the “no-touch” SV grafts that demonstrated a competitive flow in the early postoperative angiograms were patent at 1 year postoperatively. Third, leg wound complications in the SV harvesting site were not more common among patients who received SV grafts harvested using
