Non-tumoral portal vein thrombosis (PVT) is a frequent and challenging complication in liver transplant candidates. The prevalence reaches up to 26% in patients with cirrhosis on a transplant waiting list. Its severity increases with liver disease progression and significantly impacts post-transplant outcomes. Advanced PVT increases postoperative mortality to 30%. Effective management requires a multidisciplinary approach, especially in advanced cases. Preoperative strategies emphasize anticoagulation with low molecular weight heparin, while interventional radiology, including transjugular intrahepatic portosystemic shunts, offers alternatives in some cases. Intraoperatively, management is guided by PVT classification systems, ranging from thrombectomy and portal vein reconstruction to non-physiological reconstructions in complex cases. This manuscript explores the management of PVT in liver transplantation candidates, discusses strategies to optimize outcomes, and presents our institutional protocol for addressing this high-risk condition.
非肿瘤性门静脉血栓形成(PVT)是肝移植候选者中常见且具有挑战性的并发症。在移植等待名单上的肝硬化患者中,其患病率高达26%。其严重程度随肝病进展而增加,并显著影响移植后的结局。晚期PVT将术后死亡率提高到30%。有效的管理需要多学科方法,尤其是在晚期病例中。术前策略强调使用低分子量肝素进行抗凝,而介入放射学,包括经颈静脉肝内门体分流术,在某些情况下提供了替代方案。术中,管理以PVT分类系统为指导,范围从血栓切除术和门静脉重建到复杂病例中的非生理性重建。本文探讨了肝移植候选者中PVT的管理,讨论了优化结局的策略,并介绍了我们机构针对这种高危情况的方案。
