Venous Thromboembolism Diagnosis and Management

BackgroundMinimally invasive saphenous vein harvest (MIVH) techniques have been evaluated and reported with heterogeneous results. The aim of this study was to evaluate the efficacy of MIVH on the outcomes of postoperative leg wound healing and pain using the SaphLITE retractor system.MethodsTwo hundred twenty-five patients undergoing elective coronary artery bypass grafting surgery were randomized to receive either SaphLITE vein harvest (SVH) or conventional open vein harvest (OVH).ResultsThere were no significant differences between the two groups in demographics, postoperative mortalities and major complications. For SVH group and OVH group, total leg wound length was 18.33 ± 7.93 cm vs 46.10 ± 15.63 cm (p < 0.001), and vein harvest time was 50.70 ± 16.55 minutes vs 40.35 ± 16.43 minutes (p < 0.001). In-hospital leg wound healing disturbance (LWHD) rate was 4.7% for SVH group and 1.7% for OVH group (p = 0.190). Delayed LWHD rate was 16.0% for SVH group and 39.5% for OVH group (p < 0.001). Combined, LWHD rate was 20.8% for SVH group and 41.2% for OVH group (p = 0.001). There was no significant difference in the worst postoperative leg wound pain or length of hospital stay between the 2 groups. Double-blinded histologic examinations revealed normal vascular structure in the harvested veins from both groups.ConclusionsOur study demonstrated that harvesting saphenous vein with SaphLITE retractor system is a good technique which is associated with reduced rate of delayed LWHD, preserved venous structural integrity, and acceptable harvest speed.
