目的

探讨超声对成人右半肝移植架桥血管动态监测的应用价值。

方法

回顾性分析2015年1月1日至2024年6月30日在青岛大学附属医院器官移植中心接受成人右半肝移植手术的受者资料。共纳入27例受者,按照供肝切除及血管重建方式,分为不带肝中静脉(MHV)的架桥组(n=19)和带MHV的非架桥组(n=8)。收集两组受者围手术期相关资料以及术后1周内肝功能指标。利用超声动态监测术中及术后门静脉、架桥血管及Ⅴ、Ⅷ段静脉血流情况,观察频谱形态并测量血流参数。计量资料采用独立样本t检验或Mann-Whitney U检验比较,计数资料采用卡方检验或Fisher确切概率法比较。P<0.05为差异有统计学意义。

结果

架桥组和非架桥组受者性别、体质指数、终末期肝病模型评分和白蛋白水平等术前指标,手术时间、出血量、无肝期时间和输注红细胞量等术中指标,以及术后总住院时间、术后第1天和第30天门静脉流量差异均无统计学意义(P均>0.05)。架桥组和非架桥组受者术后ICU住院时间中位数分别为4.0(3.0,4.5)和6.0(5.5,7.5)d,差异有统计学意义(Z=-2.042,P<0.05)。术后1周内两组受者肝功能指标均稳步下降,差异均无统计学意义(P均>0.05)。架桥组术中及术后第1、7、14和30天架桥血管流速分别为(38.3±14.4)、(30.7±13.4)、(42.2±14.7)、(38.7±14.4)和(36.0±21.4) cm/s,血流及频谱均显示良好。架桥组移植肝Ⅴ、Ⅷ段肝静脉回流良好,术后第1天和第30天Ⅴ段静脉流速分别为(25.0±11.5)和(15.6±9.0) cm/s;术后第1天和第30天Ⅷ段静脉流速分别为(22.9±8.2)和(23.0±9.1) cm/s。

结论

超声对成人右半肝移植MHV属支重建后架桥血管的监测可发挥着重要作用,为术后早期血管并发症的检出以及移植肝再生提供敏感、有效的评估手段。

Objective

To investigate the value of ultrasound in dynamic monitoring of bridging vessels in adult right half liver transplantation.

Methods

The data of adult right half liver transplantation recipients in the Organ Transplantation Center of the Affiliated Hospital of Qingdao University from January 1, 2015 to June 30, 2024 were retrospectively analyzed. A total of 27 recipients were included and divided into bridging group (n=19) and non- bridging group (n=8) according to the mode of liver resection and middle hepatic vein (MHV) branch reconstruction. Perioperative data and liver function parameter 1 week after operation were collected. Ultrasound was used to dynamically monitor the blood flow of portal vein, bridging vessels, Ⅴ and Ⅷ segment veins during and after operation, and spectral shape was observed and blood flow parameters were measured. Measurement data were compared using independent sample t test or Mann-Whitney U test, and enumeration data were compared using chi-square test or Fisher′s exact probability test. P value <0.05 was considered statistically significant.

Results

There was no significant difference in sex, body mass index, model for end-stage liver disease score and albumin level, operation time, blood loss, anhepatic phase time and red blood cell transfusion, total postoperative hospital stay, portal vein flow on the 1st and 30th day after operation between the bridging group and the non-bridging group (P>0.05). The median postoperative ICU length of stay was 4.0 (3.0, 4.5) and 6.0 (5.5, 7.5) days in the bridging and non-bridging groups, respectively, and the difference was statistically significant (Z=-2.042, P<0.05). Within 1 week after operation, the liver function indicators of recipients in both groups steadily decreased, and the differences were not statistically significant (P>0.05). The flow velocities of the bridging vessels were (38.3±14.4), (30.7±13.4), (42.2±14.7), (38.7±14.4) and (36.0±21.4) cm/s during the operation and at 1, 7, 14, 30 days after transplantation, respectively, and the blood flow and spectrum showed well. Hepatic venous return was good in segments Ⅴ and Ⅷ of the transplanted liver, with venous flow velocities of (25.0±11.5) and (15.6±9.0) cm/s in segments Ⅴ on postoperative days 1 and 30, respectively; and (22.9±8.2) and (23.0±9.1) cm/s in segments Ⅷ on postoperative days 1 and 30, respectively.

Conclusions

Ultrasonography plays an important role in monitoring bridging vessels after MHV branch reconstruction in adult right half liver transplantation, and provides a sensitive and effective evaluation method for the detection of early postoperative vascular complications and liver allograft regeneration.
