目的
2
探讨内窥镜获取大隐静脉在冠状动脉旁路移植术中的应用并探讨学习曲线,重点关注初学者易发生的问题及对早期临床结果的影响。
方法
2
回顾性分析2013年7月至2014年4月在郑州大学第一附属医院心外科接受不停跳冠状动脉旁路移植术并使用内窥镜技术获取大隐静脉的83例患者的临床资料,按照手术时间的先后顺序分为A组(初学组20例)、B组(熟悉组20例)、C组(进步组20例)、D组(成熟组23例),分析各组之间患者围术期及随访结果差异,明确学习曲线周期。
结果
2
该组患者年龄为(60.22±8.06)岁,体质量为(69.77±11.66) kg,其中合并高血压24例、糖尿病26例、亚急性脑梗14例。A组相对于后三组获取大隐静脉长度与时间比值明显较小(
P
<
0.001),静脉主干损伤数量明显较多(
P
=0.006),并且随访1年时静脉桥通畅率较低,但差异无统计学意义。
结论
2
内窥镜获取大隐静脉之前技术操作培训是必要的,能有效规避初学者造成的血管损伤,实际获取的过程中大概需要亲自操作20例,并认真总结技术技巧就可以较为熟练地进行相关操作。
Objective
2
To investigate the application of endoscopy in obtaining the great saphenous vein (GSV) during coronary artery bypass grafting (CABG) and explore the learning curve, with a particular focus on common challenges encountered during the learning process and their impact on early clinical outcomes.
Methods
2
A retrospective analysis was conducted on clinical data from 83 patients who underwent off-pump CABG with endoscopic GSV harvesting at the First Affiliated Hospital of Zhengzhou University from July 2013 to April 2014. Patients were categorized into four groups based on the chronological order of their hospitalization: Group A (novice group,
n
=20), Group B (proficient group,
n
=20), Group C (progressive group,
n
=20), and Group D (mature group,
n
=23). Differences in perioperative and midterm follow-up outcomes among the groups were analyzed to determine the learning curve period.
Results
2
The study population had a mean age of (60.22±8.06) years and a mean body weight of (69.77±11.66) kg. Comorbidities included hypertension (24 cases), diabetes (26 cases), and subacute cerebral infarction (14 cases). The novice group exhibited significantly shorter GSV length-to-harvest time ratio relative to the other three groups (
P
<
0.001) and a significantly higher incidence of main vein damage (
P
=0.006). However, there was no statistically significant difference in graft patency at the 1-year follow-up.
Conclusion
2
Thorough and reliable technical training in endoscopic GSV harvesting is essential to minimize vascular injury caused by novice operators. Approximately 20 cases of hands-on experience and a careful self-analysis of procedural challenges are likely required to achieve proficiency in GSV harvesting.
