The clinical application of microincision vein harvesting of the great saphenous vein in coronary artery bypass grafting

Abstract

Background: The present study aimed to summarize the clinical application of microincision vein harvesting (MVH) of the great saphenous vein in coronary artery bypass grafting (CABG). Methods: From July 2014 to October 2017, 160 patients underwent coronary artery bypass grafting. Among them, 80 patients received MVH of the great saphenous vein, and 80 received open venous harvesting (OVH). The results of the sampling operation, complications during hospitalization, and the long-term patency of the great saphenous vein were compared between the two groups. Results: All the patients in both groups received successful operations. The difference in the length of the veins obtained and the injury of the veins was not statistically significant (P > 0.05). The difference in the long-term patency rate of the graft vessels between the two groups was not statistically significant. The in-hospital mortality rate was the same in both groups. The MVH group had noticeable advantages over the OVH group in terms of the vein collection times, the incision length, and the complications experienced when performing the leg incisions (P < 0.01). The time relating to the patients' observed early out-of-bed activity was significantly longer in the MVH group. Furthermore, the patients' hospitalization length was significantly shorter in the MVH group compared to the OVH group (P < 0.05). The MVH group had significant advantages in pain score and patient satisfaction, and this difference was also statistically significant (P < 0.05). Conclusions: The MVH procedure met the requirements of CABG in vein grafting. When compared with OVH, MVH can significantly reduce leg incision complications and improve patients' overall satisfaction with their hospital experience.

Bletilla striata Polysaccharide Prevents Restenosis of Vein Graft Through Inhibiting Cell Proliferation in Rat Model

“…Intimal hyperplasia of vein grafts and the proliferation of medial smooth muscle cells are two of the most important factors underlying restenosis 26,27 . During surgery, endothelial cells in the venous bridge can be damaged, thus resulting in platelet adhesion, thrombosis, and vasospasm 28,29 . Simultaneously, these damaged endothelial cells can increase the sensitivity of cytokines and induce pathological changes in the VSMCs.…”

Comparison of the mid-term clinical efficacy and short-term complications of Y-type coronary artery bypass grafting and sequential bypass grafting of the great saphenous vein: a retrospective cohort study

“…The use of the great SV [in the internal breast artery (ITA)] in CABG is prone to progressive intimal hyperplasia, resulting in mid-term sclerosis and obstruction, and has a patency rate of only 30-35% 10 years after surgery (15). As a bypass vessel, the ITA has a constant anatomical position, shows no progressive intimal hyperplasia, sclerosis, or obstruction after surgery, has a 10-year patency rate of up to 9.0%~5%, and has a similar blood supply to the great SV, which promotes the clinical use of ITA as a heart bypass vessel (16)(17)(18)(19).…”
