To determine the effects of surgical portal decompression in Budd-Chiari syndrome (BCS) on survival, quality of life, shunt patency, liver function, portal hemodynamics, and hepatic morphology during periods ranging from 3.5 to 27 years.
Experiments in the authors' laboratory showed that surgical portal decompression reversed the deleterious effects of BCS on the liver. This study was aimed at determining whether similar benefit could be obtained in patients with BCS.
From 1972 to 1999, the authors conducted prospective studies of the treatment of 60 patients with BCS who were divided into three groups: the first had occlusion confined to the hepatic veins treated by direct side-to-side portacaval shunt (SSPCS); the second had occlusion involving the inferior vena cava (IVC) treated by a portal decompressive procedure that bypassed the obstructed IVC; and the third group, who had advanced cirrhosis and hepatic decompensation and were referred too late for treatment by portal decompression, required orthotopic liver transplantation.
In the 32 patients with BCS resulting from hepatic vein occlusion alone, SSPCS had a surgical death rate of 3%, and 94% of the patients were alive 3.5 to 27 years after surgery. All 31 survivors remained free of ascites and almost all had normal liver function. No patient with a patent shunt had encephalopathy. The SSPCS remained patent in all but one patient. Liver biopsies showed no evidence of congestion or necrosis, and 48% of the biopsies were diagnosed as normal. Mesoatrial shunt was performed in eight patients with BCS caused by IVC thrombosis. All patients survived surgery, but five subsequently developed thrombosis of the synthetic graft and died. Because of the poor results, mesoatrial shunt was abandoned. Instead, a high-flow combination shunt was introduced, consisting of SSPCS combined with a cavoatrial shunt (CAS) through a Gore-Tex graft. There were no surgical or long-term deaths among 10 patients who underwent combined SSPCS and CAS, and the shunts functioned effectively during 4 to 16 years of follow-up. Ten patients with advanced cirrhosis were referred too late to benefit from surgical portal decompression, and they were approved and listed for orthotopic liver transplantation. Three patients died of liver failure while awaiting a transplant, and four patients died after the transplant. The 1- and 5-year survival rates were 40% and 30%, respectively.
SSPCS in BCS with hepatic vein occlusion alone results in reversal of liver damage, correction of hemodynamic disturbances, prolonged survival, and good quality of life when performed early in the course of BCS. Similarly good results are obtained with combined SSPCS and CAS in patients with BCS resulting from IVC occlusion. In contrast, mesoatrial shunt has been discontinued in the authors' program because of an unacceptable incidence of graft thrombosis and death. In patients with advanced cirrhosis from long-standing, untreated BCS, orthotopic liver transplantation is the only hope of relief and results in the salvage of some patients. The key to long survival in BCS is prompt diagnosis and treatment by portal decompression.
确定布加综合征(BCS)手术门体分流减压对3.5至27年期间生存率、生活质量、分流通畅情况、肝功能、门静脉血流动力学及肝脏形态的影响。
作者实验室的实验表明,手术门体分流减压可逆转BCS对肝脏的有害影响。本研究旨在确定BCS患者是否能获得类似益处。
1972年至1999年,作者对60例BCS患者进行了前瞻性治疗研究,将其分为三组:第一组为肝静脉闭塞,采用直接门腔侧侧分流术(SSPCS)治疗;第二组为下腔静脉(IVC)闭塞,采用绕过阻塞IVC的门体减压术治疗;第三组为晚期肝硬化和肝功能失代偿,因转诊过晚无法进行门体减压治疗,需进行原位肝移植。
在仅由肝静脉闭塞导致BCS的32例患者中,SSPCS手术死亡率为3%,94%的患者术后3.5至27年存活。所有31名幸存者均无腹水,几乎所有患者肝功能正常。分流通畅的患者无一发生肝性脑病。除1例患者外,SSPCS均保持通畅。肝脏活检未发现充血或坏死迹象,48%的活检结果诊断为正常。对8例由IVC血栓形成导致BCS的患者进行了肠系膜心房分流术。所有患者手术存活,但5例随后出现人工血管血栓形成并死亡。由于效果不佳,放弃了肠系膜心房分流术。取而代之的是引入了一种高流量联合分流术,即通过Gore-Tex人工血管将SSPCS与腔房分流术(CAS)相结合。10例接受SSPCS和CAS联合手术的患者无手术或长期死亡,分流在4至16年的随访中有效发挥作用。10例晚期肝硬化患者转诊过晚,无法从手术门体分流减压中获益,他们被批准并列入原位肝移植名单。3例患者在等待移植期间死于肝功能衰竭,4例患者移植后死亡。1年和5年生存率分别为40%和30%。
对于仅肝静脉闭塞的BCS患者,早期进行SSPCS可逆转肝损伤、纠正血流动力学紊乱、延长生存期并提高生活质量。对于由IVC闭塞导致BCS的患者,SSPCS与CAS联合手术也能取得同样良好的效果。相比之下,由于人工血管血栓形成和死亡发生率过高,作者已停止使用肠系膜心房分流术。对于长期未治疗的BCS导致晚期肝硬化的患者,原位肝移植是缓解病情的唯一希望,且能挽救部分患者。BCS患者长期存活的关键在于及时诊断并通过门体分流减压进行治疗。
