背景。前段额外静脉重建对右叶肝移植物充血的疗效尚未得到充分研究。方法。在右叶活体肝移植中使用磁共振成像评估移植后移植物静脉充血情况。额外的静脉重建分为两种类型：第5或8段支流重建（n=11）和肝中静脉（MHV）重建（n=9）。仅具有右侧肝静脉（包括右肝静脉）的四十五个移植物用作对照。结果。尽管重建通畅，但移植后 1 个月，V5/8 移植物和标准移植物之间的眼前节充血评分没有显着差异。仅具有 MHV 的移植物未显示充血（P <0.01）。结论。当放射学评估时，眼前段支流的引流重建仅产生次优的益处。增加MHV主干与其周围的交通，对眼前段充血效果最好。
Background. The efficacy of additional venous reconstruction in the anterior segment has not been fully investigated for graft congestion in right-lobe liver grafts. Methods. Posttransplant graft venous congestion in the anterior segment was evaluated using magnetic resonance imaging in right-lobe living-donor liver transplantation. Additional venous reconstruction was categorized into two types: reconstruction of tributaries from segment 5 or 8 (n=11) and reconstruction of the middle hepatic vein (MHV) (n=9). Forty-five grafts only with right-sided hepatic vein(s) including the right hepatic vein served as controls. Results. No significant difference in congestion score of the anterior segment was observed between grafts with V5/8 and standard grafts 1 month after transplantation despite the patency of reconstruction. Only grafts with the MHV showed no congestion (P <0.01). Conclusions. Drainage reconstruction of tributaries from the anterior segment produces only suboptimal benefits when evaluated radiologically. The addition of the main trunk of the MHV with its surrounding communication has the best effect on the congestion of the anterior segment.
