摘 要:目的探讨肝静脉分型及肝移植技术规范实践中的常见弊端及其对策。方法回顾性分析作者自2000年5月至2007年8月实施的共248例成人肝移植病例资料。将248例受者肝静脉进行解剖分型(I、Ⅱ、Ⅲ、Ⅳ-A、IV-B、V型)。以背驮式肝移植为基本技术,并根据肝静脉分型分别实施了经典背驮式肝移植、改良背驮式肝移植和经典式原位肝移植。结果对136例I型(左、中肝静脉合干型)患者实施经典背驮式肝移植。其中6例肝静脉分离失败,34例发生即期(14例,9.85%)、急性(18例,12.67%)、慢性(2例,1.40%)布-加综合征者,后经手术矫正、降低门静脉压疗法和肝后下腔静脉放置下腔静脉支架处理后,肝静脉回流受阻均得到改善。对54例Ⅱ型(右、中肝静脉合干型)患者均行经典背驮式肝移植术,无肝静脉回流受阻。其中2例肝静脉被肿瘤包绕改行经典式原位肝移植。对14例Ⅲ型(三支肝静脉合干型)患者行经典背驮式肝移植术最理想,无肝静脉回流受阻。对16例Ⅳ-A型(三支肝静脉同轴型)患者行经典式原位肝移植,2例成型失败行改良背驮式肝移植。Ⅳ-B型(三支肝静脉非同轴型)18例行改良背驮式肝移植和经典式原位肝移植各9例。V型(肝段型,无三支恒定的肝静脉)4例行改良背驮式肝移植和经典式原位肝移植各2例。在施行改良背驮式肝移植和经典式原位肝移植术的患者中有3例发生布-加综合征,术后1—3月分别实施肝后下腔静脉置放下腔静脉支架术,术后布-加综合征症状缓解。结论按肝静脉分型可科学地规范肝移植技术。I型行经典背驮式肝移植,由于肝静脉回流偏左,易扭曲,故即期、急性、慢性布-加综合征的发生率较高。Ⅱ、Ⅲ型行经典背驮式肝移植则无肝静脉回流受阻;III型行经典背驮式肝移植最理想。Ⅳ-A型可行经典背驮式Objective To investigate the hepatic vein (HV) classification and its common drawbacks in the application of the liver transplantation (LT) and explore the solution for the problems. Meth- otis Retrospectively, data of 248 patients with LT performed from May 2000 to August 2007 were analyzed. The hepatic veins of 248 recipients had been classified into 5 types : I , II, III, IV-A, IV-B, V. Based on the piggyback liver transplantation (PBLT) technology and the HV classification, we implemented classical piggyback liver transplantation ( CPBLT), ameliorative piggyback liver transplantation (APBLT) and classi- cal orthotopic liver transplantation (COLT). Results 136 cases of Type I (left and middle hepatic vein common trunk) was implemented with CPBLT, of which 6 cases underwent HV separation failure. Thirtyfour cases developed Budd-chiari syndrome ( BCS ) : immediate BCS ( n = 14, 9. 85% ), acute BCS (n = 18, 12. 67% ), chronic BCS (n =2, 1.40% ).. The hepatic venous outflow obstruction (HVOO) was improved through the application of surgery aiming at reducing portal pressure and stenting in retrohepatic inferior vena cava (RHIVC). No HVOO occurred in the 54 cases with Type II ( right and middle hepatic vein common trunk)who underwent CPBLT surgery, including two cases with the HV surrounded by tumor diverted into COLT. The best choice for the patients with Type III (three hepatic veins common trunk) of HV is CPBLT and no HVOO occurred. Sixteen cases with Type IV-A (three hepatic veins coaxial) accepted CPBLT with 2 cases diverted to APBLT after vessel molding failure. APBLT ( n = 9 ) and COLT ( n = 9 ) were performed in 18 cases with Type IV-B (three hepatic veins non-coaxial). Four cases of Type V (liver segment type, no three constant hepatic vein) underwent APBLT (n = 2) and COLT (n = 2). Three cases in APBLT and COLT implementations got BCS respectively and achieved symptoms remission after stenting in RHIVC 1 to 3 month
