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).
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.
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).
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.
本研究旨在总结微创大隐静脉采集（MVH）在冠状动脉旁路移植术（CABG）中的临床应用。
2014 年 7 月至 2017 年 10 月，160 例患者接受冠状动脉旁路移植术。其中，80 例行 MVH 取大隐静脉，80 例行开放式静脉采集（OVH）。比较两组患者的取样操作结果、住院期间并发症及大隐静脉长期通畅率。
两组患者均顺利完成手术。两组间获取静脉的长度和静脉损伤无统计学差异（P>0.05）。两组间移植血管的长期通畅率无统计学差异。两组住院死亡率相同。MVH 组在静脉采集次数、切口长度和腿部切口并发症方面明显优于 OVH 组（P<0.01）。MVH 组患者观察早期下床活动的时间明显延长。此外，MVH 组患者的住院时间明显短于 OVH 组（P<0.05）。MVH 组在疼痛评分和患者满意度方面具有显著优势，差异有统计学意义（P<0.05）。
MVH 术式符合 CABG 静脉移植物的要求。与 OVH 相比，MVH 可明显减少腿部切口并发症，提高患者对住院体验的整体满意度。
