An in-depth understanding of portal venous anatomy, particularly its variants, is essential for interventional radiologists performing complex hepatobiliary procedures such as transjugular intrahepatic portosystemic shunt (TIPS) creation. Anatomical variations in the portal venous system occur in approximately 35% of the population, and failure to identify these variants can result in significant procedural complications including vascular injury and postprocedural liver failure. This article discusses the most common (types I-V) portal vein variants and the importance of their preprocedural identification, their potential impact on procedural outcomes, and the role of advanced imaging techniques in mitigating risks associated with these anatomical variations.
深入了解门静脉解剖结构，尤其是其变异情况，对于进行诸如经颈静脉肝内门体分流术（TIPS）创建等复杂肝胆手术的介入放射科医生来说至关重要。门静脉系统的解剖变异在大约35%的人群中出现，未能识别这些变异可能导致包括血管损伤和术后肝衰竭在内的重大手术并发症。本文讨论了最常见的（I - V型）门静脉变异、术前识别它们的重要性、它们对手术结果的潜在影响，以及先进成像技术在降低与这些解剖变异相关风险方面的作用。
