Portal vein embolization (PVE) is used to induce preoperative liver hypertrophy in patients with anticipated marginal future liver remnant (FLR) volumes who are otherwise potential candidates for resection. PVE can be performed utilizing the transhepatic contralateral and ipsilateral approaches. The transhepatic contralateral approach is the most commonly used technique worldwide, largely owing to its technical ease. However, the contralateral approach risks injuring the FLR, thereby compromising the planned surgical resection. The transhepatic ipsilateral approach offers a potentially safer alternative because the complications associated with this approach affect only the hepatic lobe that will be resected and are usually not serious enough to preclude surgery. This article discusses PVE using the transhepatic ipsilateral and contralateral approaches, including patient selection criteria, anatomical and technical considerations, and patient complications and outcomes.
门静脉栓塞术（PVE）用于诱导预期未来肝剩余（FLR）体积处于临界状态的患者术前肝脏肥大，这些患者原本是潜在的手术切除候选人。PVE可通过经肝对侧和同侧途径进行。经肝对侧途径是全球最常用的技术，这主要归功于其操作简便。然而，对侧途径有损伤FLR的风险，从而影响计划中的手术切除。经肝同侧途径提供了一种潜在更安全的替代方法，因为与该途径相关的并发症仅影响将要切除的肝叶，且通常不严重到足以排除手术。本文讨论了经肝同侧和对侧途径的PVE，包括患者选择标准、解剖和技术考量以及患者并发症和结局。
