原位肝移植术中结扎门体分流静脉的临床研究

Objective To investigate the clinical significance of ligating the portasystemic shunt confirmed by preoperative CT evaluation during orthotopic liver transplantation. Methods From January 2007 to August 2008, 35 patients in Tianjin First Central Hospital underwent preoperative three-dimensional CT scan, among them 23 patients had spontaneous major portasystemic shunts, the other 12 patients did not have portasystemic shunts. 16 out of the 23 cases with significant shunts underwent shunt ligation based on portal blood flow volume measured by intraoperative portal vein flowmetry. The shunt of the other 7 patients were left untreated. Results The portal blood flow in the 12 patients without portasystemic shunt as judged by preoperative CT scanning were (1101±70) ml/min. The shunts in 7 patients with portal blood flow greater than 1000 ml/min were not ligated, that of the 16 patients with portal blood flow volume lower than 1000 mL/min were ligated. The portal blood flow volume in those 16 patients before and after ligating the shunt were (657±112) m//min and (1136±161) ml/min, respectively (P<0.05). Postoperatively 2 patients suffered from portal vein thrombosis, among them 1 patient suffered from intermittent disturbance of consciousness, 2 patients died within 3 months, with one dying of respiratory failure from pulmonary aspergillus infection one dying of hepatic failure in 2 months after operation because of graft dysfunction.The other 19 patients with normal blood flow and well-functioning graft were alive. Conclusion The ligation of portasystemic shunt is mandatory in patients when pretransplant CT evaluation showing a major porto-systemic shunts and portal blood flow volume was less than 1000 ml/min.

Outcome of patients with pre-existing portal vein thrombosis undergoing arterialization of the portal vein during liver transplantation

Arterialization of the portal vein is being propagated as a technical possibility in liver transplant recipients with pre-existing portal vein thrombosis. In our own small series, portal vein arterialization (PVA) was carried out in four patients undergoing orthotopic liver transplantation. In three of these cases, the portal vein was anastomosed to the aorta via an interposed iliac artery, and in one case, directly to the hepatic artery. After PVA, all transplants showed regular initial function. Two patients died postoperatively after 19 and 50 days, of intra-abdominal haemorrhage and liver necrosis with thrombosis of the portal vein, respectively. A further patient had previously developed fibrosis of the liver, which led to the death of the patient 11 months after PVA. In the remaining patient, chronic rejection requiring re-transplantation developed 24 months after PVA had been performed. These unfavourable results prompt the conclusion that PVA cannot be recommended as a standard clinical procedure.     

Rescue of Acute Portal Vein Thrombosis After Liver Transplantation Using a Cavoportal Shunt at Re-transplantation

BACKGROUND: Portal vein thrombosis is a rare but devastating complication following orthotopic liver transplantation. Fulminant liver failure ensues with acute portal vein thrombosis after transplantation limiting the treatment options. METHODS: We successfully re-transplanted a 46-year-old female patient who developed acute portal vein thrombosis 19 d after orthotopic liver transplantation. Vascular reconstruction included a cavoportal shunt to augment portal blood flow. RESULTS: Twelve months after re-transplantation this patient lives independently and enjoys excellent liver allograft function. CONCLUSIONS: Cavoportal shunt can augment portal blood flow in adult recipients of orthotopic liver transplants. This technique can be successfully employed during re-transplantation when portal blood flow is inadequate to maintain patency.

Eversion thromboendovenectomy for organized portal vein thrombosis encountered during liver transplantation

INTRODUCTION: Due to the technical experience acquired in the field of liver transplantation portal vein thrombosis is no longer considered a contraindication for transplantation. Nevertheless, the results obtained in patients with portal vein thrombosis are at times suboptimal, and there is no consensus on the appropriate surgical technique. PATIENTS AND METHODS: Among the 455 liver transplants performed between May 1988 and December 2001, 32 (7%) presented with portal vein thrombosis. Twenty (62%) were type Ib, seven (22%) type II/III, and five (16%) type IV. Twenty-two were men (69%), with a mean age of 50 years (range: 30-70 years); the thrombosis in all cases developed in a cirrhotic liver. The surgical method in all cases consisted of an eversion thromboendovenectomy under direct visual guidance, with occlusion of the portal flow using a Fogarty balloon. RESULTS: Among the 32 cases undergoing thrombectomy, 31 (96%) were successful with a failure in a case of type IV thrombosis, which was resolved by portal arterialization. Of the 31 successful cases, only one with type IV thrombosis rethrombosed. The 5-year survival rate of the patients in the series was 69%. Only two patients died from causes related to the thrombosis, both showing type IV thrombosis. CONCLUSION: The ideal treatment for portal thrombosis during liver transplantation depends on its extension and on the experience of the surgeon. In our experience, eversion thromboendovenectomy resolves most thromboses (types I, II, and III), but management of type IV, which occasionally can be treated with this technique, may require more complex procedures such as bypass, portal arterialization or cavoportal hemitransposition.     

Portosystemic shunt for the treatment of portal vein thrombosis following orthotopic liver transplantation

Abstract The efficacy of the portosystemic shunt operation for the treatment of portal vein thrombosis following orthotopic liver transplantation was demonstrated. From 1 July 1988 to 31 December 1991 42 portosystemic shunt operations were performed at our centre. In six of these cases portal vein thrombosis after orthotopic liver transplantation (OLT) was the indication for the procedure. All the patients retained adequate liver function but they demonstrated manifestations of significant portal hypertension, mainly variceal rebleeding. Two of the patients were children. Three patients underwent distal splenorenal shunt (DSRS), one mesocaval and one side-to-ide splenorenal shunt and the last one side-to-ide splenorenal shunt which was converted to DSRS 2 weeks later. All these patients were doing well after 30 months mean follow-up time without rebleeding or other signs of portal hypertension and none had so far required retransplantation.     

肝脏再移植原因及效果分析

目的探讨再次肝移植的原因及效果,并比较不同供肝来源与再移植的关系。 方法回顾性分析2000年1月至2018年5月四川大学华西医院1 429例肝移植受者临床资料。首次肝移植供肝来源分别为尸体供肝686例、心脏死亡器官捐献(DCD)供肝346例和活体供肝397例。其中31例受者接受再次肝移植(32例次,其中1例受者接受2次再移植),再移植率为2.24%(32/1 429),供肝来源分别为尸体供肝23例、DCD供肝6例、活体供3例。再移植间隔时间中位数为311 d(88～845 d),间隔1～7 d 3例,8～30 d 1例,31～365 d 15例,>1年13例。采用Kaplan-Meier法计算肝脏再移植术后受者生存时间并绘制生存曲线,采用Breslow法比较再移植间隔时间>1年及≤1年的受者1、5和10年生存率,采用Fisher确切概率法比较不同供肝来源的受者再移植率。P<0.05为差异有统计学意义。 结果截至2018年5月,31例肝脏再移植受者术后12例存活(38.7%)、19例死亡(61.3%),中位生存时间为17个月(2～102个月)。尸体供肝、DCD供肝和活体供肝再移植率分别为3.4%(23/686)、1.7%(6/346)和0.8%(3/367)。尸体供肝再移植率高于活体肝移植,差异有统计学意义(P＝0.007),DCD供肝再移植率与尸体供肝、活体供肝再移植率相比,差别均无统计学意义(P＝0.137和0.222)。其中18例再移植间隔时间<1年的受者,6例存活、12例死亡;13例再移植间隔时间≥1年的受者,6例存活、7例死亡。31例肝脏再移植受者术后1、5和10年生存率分别为64.2%、51.2%和46.6%。再移植间隔时间<1年的受者1、3和5年生存率分别为49.4%、41.2%和30.9%,间隔时间≥1年的受者1、3和5年生存率分别为84.6%、65.8%和65.8%,二者差异无统计学意义(χ²＝2.946,P>0.05)。 结论再移植是肝移植术后移植物失功的唯一有效治疗方法,再移植术后受者往往病情危重,围手术期死亡率高,胆道并发症及排斥反应是再次肝移植的主要原因。应该慎重把握再移植手术时机,目前亟待更多的研究对再移植做进一步探讨。
