摘要
目的：应用128层螺旋CT检查，评价肝右静脉及右肝下副静脉的解剖。方法：432例患者行128层螺旋CT检查，对肝静脉图像进行后处理，观察其解剖细节。结果：Nakamura分型，Ⅰ型274例（占63.43%），Ⅱ型108例（占25%），Ⅲ型50例（占11.57%）。肝右静脉起始处直径（10.68±3.18） mm，主干长度（10±2.37） cm。96例患者出现114条右肝下副静脉，直径（4.43±1.48） mm，主干长度（6.34±2.22） cm，18例患者有2条右肝下副静脉。肝右静脉与右肝下副静脉汇入下腔静脉处间距为（4.74±1.28） cm。结论：术前128层螺旋CT检查可显示肝右静脉及右肝下副静脉的详细解剖，为肝脏外科手术提供准确信息。
Abstract
Objective: To assess the anatomy of right hepatic vein and accessory right inferior hepatic vein with 128-MSCT angiography. Methods: 432 patients underwent 128-MSCT abdominal CT scan. All data were reconstructed to observe the anatomic details of the hepatic veins. Results: According to Nakamura’s classification of hepatic veins, 274 patients were classified as type Ⅰ(63.43%）, 108 patients were classified as type Ⅱ(25%）, and 50 patients were classified as type Ⅲ(11.57%）. The initial diameter of right hepatic vein was (10.68±3.18) mm, and the length of trunk was (10±2.37) cm. 114 accessory right inferior hepatic vein were found in 96 patients. The initial diameter of the accessory right inferior hepatic vein was (4.43±1.48) mm, and the length of trunk was(6.34±2.22) cm. Two accessory right inferior hepatic veins were found in 18 patients. The distance between the openings of the right hepatic vein and the accessory right inferior vein into the inferior vena cava was (4.74±1.28) cm. Conclusion: 128-MSCT can offer detailed anatomy of the right hepatic vein and the accessory right inferior vein before operation and can supply accurate information for hepatic surgery.
