Abstract

Liver has exceptional regeneration capacity which makes live donor liver transplantation a good surgical option for patients waiting for donors. Hepatic veins play major role in transplantation surgeries. Variations of hepatic veins can have great impact on surgical approach and outcome of the surgery. In the present study, total number of hepatic veins, presence and absence of accessory veins and confluence with its varied patterns were studied. We found maximum cases with 2 and 3 major hepatic veins which indicate presence of confluence. Confluence between left and middle hepatic veins was highest with 38% of total 54% of cases with confluence. We also found confluence between middle and accessory hepatic vein which is not mentioned in any present classifications. In addition, we have measured confluence length and diameter which holds significance in hepatic resection and anastomosis. The mean confluence length was 0.88±0.39 cm while mean confluence diameter was 0.57±0.20 cm. We found accessory hepatic veins in 15% of cases. The knowledge of this surgical anatomy and associated variations is of paramount importance in liver transplantation, radiological interventional procedures of liver and hepatic tumor resection procedures.

肝静脉汇流在肝移植中的应用研究。
肝脏具有超强的再生能力,这使得活体肝移植成为等待供体的患者的最佳手术选择。肝静脉在移植手术中扮演着重要角色。肝静脉的变化会对手术方法和手术结果产生重大影响。在本研究中,我们研究了肝静脉的总数、有无附属静脉以及汇合方式的变化。我们发现最多病例有 2 条和 3 条主要肝静脉,这表明存在汇合。肝左静脉和肝中静脉汇合的病例最多,占汇合病例总数 54% 的 38%。我们还发现了肝中静脉和肝附属静脉之间的汇合,这在目前的分类中都没有提及。此外,我们还测量了汇合处的长度和直径,这对肝切除和吻合术具有重要意义。平均汇合长度为 0.88±0.39 厘米,平均汇合直径为 0.57±0.20 厘米。我们在 15% 的病例中发现了附属肝静脉。了解这种手术解剖结构和相关变异对肝移植、肝脏放射介入手术和肝肿瘤切除手术至关重要。
