| 目的 采用MSCTA评价正常成人胃左静脉(LGV)的解剖及变异,探讨其临床价值。方法 选取上腹部或全腹部增强扫描正常的234名成人,采用MIP、VR和MPR多种后处理技术结合轴位薄层重建图像对门静脉和LGV图像进行重建,观察LGV正常解剖及变异,并按照其汇入门静脉系部位不同分为A、B、C、D四组。在汇入点2 cm以内测量LGV最大内径,进行统计学分析。结果 234名受检者中,11名(11/234,4.70%)LGV未见明确显示,其余223名(223/234,95.30%)LGV均清晰显示,汇入部位包括(A~D组):门静脉主干(108/234,46.15%)、脾静脉(72/234,30.77%)、门脾角(34/234,14.53%)、门静脉左支(9/234,3.85%)。正常成人LGV最大内径为(4.74±0.84)mm,95%可信区间为4.63~4.85 mm。A、B、C、D四组间最大LGV内径比较差异无统计学意义(P＞0.05)。结论 MSCTA可以客观显示LGV解剖及变异,为临床诊断LGV病变提供参考。 |

| Objective To evaluate the anatomy and variation of left gastric vein (LGV) in normal adults with MSCTA, and to assess its clinical value. Methods Imaging data of 234 normal adults underwent 16-slice spiral CT in upper abdominal or whole abdominal were retrospectively analyzed. MIP, VR and MPR combined with the cross-sectional thin-layer reconstruction were applied for vascular reconstruction of portal vein and the LGV. Normal anatomy and variations of LGV were observed and divided into A, B, C, D groups according to drainage of LGV. The maximum diameter of the LGV was measured at the point within 2 cm from the draining point of LGV, and statistical analysis was made. Results Of 234 subjects, LGV in 11 (11/234, 4.70%) subjects were not well displayed, and excellent images of LGV were obtained in 223 (223/234, 95.30%) subjects. The draining point of LGV included the portal vein (108/234, 46.15%, group A), the splenic vein (72/234, 30.77%, group B), the portal splenic angle (34/234, 14.53%, group C) and the left branch of the portal vein (9/234, 3.85%, group D). The maximum diameter of the LGV was (4.74±0.84)mm with 95% confidence interval of 4.63—4.85 mm. There was no statistical difference of maximum diameter of the LGV among the four groups (P＞0.05). Conclusion MSCTA has the ability to clearly show the diameter and detailed anatomy of LGV, providing references for clinical evaluation of LGV. |
