背景静脉引流模式在活体肝移植中至关重要。本研究的目的是通过 Pringle 线及其右半肝和左半肝的引流量确定 3D 肝脏模型中肝中静脉 (MHV) 的“解剖-地形”和“区域-生理”模式。方法通过 3-D CT 重建和虚拟评估 137 名连续活体捐献者候选者。 肝切除术。根据 MHV 的右 (R) 和左 (L)、解剖 (A) 和领地 (T) 归属模式,每个个体被分配到四种可能类型之一:I 型:AR–TR; II型:AL-TL; III型:AR-TL; IV型:AL-TR。 Couinaud 的解剖 MHV 变体 A–C 随后被纳入我们的解剖/领地 MHV 归属分类组合中。 结果 MHV 显示出右侧“解剖”(59.1%)和左侧“领地”归属模式(65.7%)的显着优势。 AR-TL(III 型)和 AL-TR(IV 型)的矛盾组合分别出现在 36.5% 和 11.7% 的病例中。属于 Couinaud 的 A 型 IV 型和属于 IV 型的 Couinaud C 型可以预测右半肝静脉充血。结论(1) 我们的研究系列中几乎一半的肝脏具有矛盾的“解剖”/“领地”MHV 归属模式,使它们面临左右肝切除术的风险。 (2) 拟议的组合“解剖”/“领域”MHV 归属类型 (I-IV) 提供了有用的术前信息。 (3) III 型和 IV 型组合以及 Couinaud 的 A–IV 型和 Couinaud 的 C–IV 型应被认为对于右半肝移植物和扩大的左肝切除术中的静脉充血风险特别大。
BACKGROUNDVenous drainage patterns are of vital importance in live donor liver transplantation. The purpose of this study was to delineate “anatomical-topographical” and “territorial-physiologic” patterns of the middle hepatic vein (MHV) in a 3-D liver model as determined by the Pringle line and its drainage volume of the right and left hemilivers.METHODSOne hundred thirty-seven consecutive live donor candidates were evaluated by 3-D CT reconstructions and virtual hepatectomies. Based on right (R) and left (L), anatomical (A) and territorial (T) belonging patterns of the MHV, each individual was assigned to one of four possible types: type I:AR–TR; type II:AL–TL; type III:AR–TL; type IV:AL–TR. Couinaud's anatomical MHV variants A–C were subsequently included in our combined anatomical/territorial MHV belonging classification.RESULTSThe MHV showed a significant predominance of right “anatomical” (59.1%) and left “territorial” belonging patterns (65.7%). The paradoxical combinations AR–TL(type III) and AL–TR(type IV) were encountered in 36.5% and 11.7% of cases, respectively. The constellations Couinaud's A-belonging type IV and Couinaud's C-belonging type IV were predictive of right hemiliver venous congestion.CONCLUSIONS(1) Almost half of all livers in our series had paradoxical “anatomical”/“territorial” MHV belonging patterns that placed them at risk for right and left hepatectomies. (2) The proposed combined “anatomical”/“territorial” MHV belonging types (I–IV) provide useful preoperative information. (3) Combined types III and IV as well as Couinaud's A–IV, and Couinaud's C–IV should be considered particularly risky for venous congestion in right hemiliver grafts and in extended left hepatectomies.
