Vascular structures of the liver and the bile ducts are crucial during liver transplantation or liver resection surgery. Here, we report on variations in the vascular structures and bile ducts of 200 patients.
We reviewed magnetic resonance cholangiopancreatographic and multiple-detector computed tomographic data.
Michels type 1 was detected in 54% of the patients. The other most common variations were, respectively, Michels type 5 (13%) and type 2 (11%). Unclassified variations were defined as Michels type 11; 5% of patients were in this group. Type 1 variations in the hepatic portal vein were detected in 76% of our study group. Other common variations were type 2 (9%) and type 3 (8.5%). The left and intermediate hepatic veins united to become a single vein and then joined the inferior vena cava in 64% of the patients. The right, intermediate, and left hepatic veins joined the inferior vena cava separately in 36% of the patients. Type A, which represents the classic anatomy of the bile duct, was observed in 51.5% of our patients. Type C1 and type B were detected in 15% and 12% of patients, respectively.
We describe vascular and biliary variations in the livers of our patients.
肝脏和胆管的血管结构在肝移植或肝切除手术中至关重要。在此，我们报告200例患者的血管结构和胆管变异情况。
我们回顾了磁共振胰胆管造影和多排螺旋计算机断层扫描数据。
54%的患者检测到米歇尔1型。其他最常见的变异分别为米歇尔5型（13%）和2型（11%）。未分类的变异定义为米歇尔11型；5%的患者属于该组。在我们的研究组中，76%的患者检测到肝门静脉1型变异。其他常见变异为2型（9%）和3型（8.5%）。64%的患者左肝静脉和肝中静脉汇合为一条静脉，然后汇入下腔静脉。36%的患者右肝静脉、肝中静脉和左肝静脉分别汇入下腔静脉。我们51.5%的患者观察到代表胆管经典解剖结构的A型。分别有15%和12%的患者检测到C1型和B型。
我们描述了我们患者肝脏中的血管和胆管变异情况。
