目的

探讨CT血管造影(CTA)术前评价供者肝静脉分布及变异对肝右叶活体肝移植的临床意义。

方法

回顾性分析2007年5月至2016年4月在中山大学附属第三医院行肝右叶活体肝移植供肝捐献的40例供者临床资料。其中男37例,女3例;年龄18~57岁,中位年龄46岁。所有供者均签署知情同意书,符合医学伦理学规定。供者术前均以多平面重建(MPR)、3D最大密度投影(MIP)、容积再现(VR)显示肝中静脉(MHV)和肝右静脉(RHV)主干及分支。按Neumann分型将MHV分为1、2、3型,记录引流肝Ⅴ段和Ⅷ段粗大属支的管径与支数;按Nakamura分型将RHV分为A、B、C型,并记录管径>5 mm的副肝静脉支数。

结果

40例供者均顺利完成CTA,均清楚显示MHV和RHV。MHV的Neumann 1型占68%(27/40),2型12%(5/40),3型20%(8/40)。RHV的Nakamura A型占78%(31/40),B型12%(5/40),C型10%(4/40)。17例肝右叶副肝静脉直径>5 mm,其中A型者9例,B型者4例,C型者4例。21例供者进行了肝右叶活体肝移植供肝捐献,带MHV肝移植14例,不带MHV肝移植7例。手术证实术前CTA显示MHV、RHV的分型以及粗大肝右叶副肝静脉的支数与术中所见100%吻合。

结论

CTA血管造影能够清晰显示MHV、RHV及肝右叶副肝静脉解剖和变异并进行准确分型,为肝右叶活体肝移植术前决定MHV取舍提供详细的影像学解剖信息。

Objective

To investigate the clinical significance of CT angiography (CTA) in preoperative evaluation of the distribution and variation of donor hepatic veins before right lobe living donor liver transplantation.

Methods

Clinical data of 40 donors undergoing right lobe living donor liver transplantation in the Third Affiliated Hospital of Sun Yat-sen University between May 2007 and April 2016 were retrospectively analyzed. Among them, 37 donors were male and 3 were female, aged 18-57 years with a median age of 46 years. The informed consents of all donors were obtained and the local ethical committee approval was received. Before operation, the middle hepatic veins (MHV) and right hepatic veins (RHV) and branches of donors were evaluated by multiplanar reformation (MPR), 3D maximum intensity projection (MIP) and volume rendering (VR) techniques. According to the Neumann classification, MHV were divided into type 1, 2 and 3. The diameter and quantity of major drainage branch of liver segment Ⅴ and Ⅷ were measured. Based upon the Nakamura classification, RHV were divided into type A, B and C. The quantity of accessory hepatic veins with diameter >5 mm was measured.

Results

All 40 donors underwent CTA successfully. Both MHV and RHV were clearly displayed. The percentage of Neumann type 1 MHV was 68% (27/40), type 2 was 12% (5/40) and type 3 was 20% (8/40). The percentage of Nakamura type A RHV was 78% (31/40), type B was 12% (5/40) and type C was 10% (4/40). There were 17 donors with the diameter of accessory hepatic veins of right lobe >5 mm, including 9 cases of type A, 4 of type B and 4 of type C. Twenty-one donors underwent right lobe living donor liver transplantation, including 14 cases of liver transplantation with MHV, 7 cases of liver transplantation without MHV. Preoperative CTA evaluation of MHV and RHV classification, quantity of major accessory hepatic veins of right lobe was found 100% consistent with the intraoperative findings.

Conclusions

CTA can clearly display the MHV, RHV, anatomy, variation and classification of accessory hepatic veins of right lobe, which can provide detailed imaging and anatomical data for treating MHV during right lobe living donor liver transplantation.
