摘　　要：目的描述双下腔静脉(inferior vena cava,IVC)的影像特点和临床特征,并总结其临床意义。方法回顾性收集2013年1月至2023年8月首都医科大学附属北京友谊医院诊断的53例双IVC患者,分析其CT影像和双IVC走行特点。结果4例患者有下肢深静脉血栓形成,其余患者均因其他疾病就诊检查时发现。患者左右侧IVC直径的差异无统计学意义(P=0.281)。50例患者为左侧IVC和左肾静脉汇合后自腹主动脉前方汇入右侧IVC,1例左侧IVC在肾静脉下约第3腰椎水平自腹主动脉后方汇入右侧IVC;1例左侧IVC和左肾静脉汇合后自腹主动脉后方汇入右侧IVC;1例内脏完全转位患者双IVC在第10胸椎水平汇合。结论双IVC可通过CT检查明确诊断,识别双IVC畸形在影像诊断、腹膜后手术和血管介入等方面具有重要意义,并应重视特殊类型走行的个体化评估。Objective To describe the imaging and clinical characteristics of double inferior vena cava(IVC)and summarize its clinical significance.Methods The clinical data of 53 patients with double IVC diagnosed in Beijing Friendship Hospital,Capital Medical University from January 2013 to August 2023 was collected retrospectively,and their CT images and the characteristics of the travelling of double IVC were analyzed.Results Four patients had deep vein thrombosis of lower extremities,and the other patients were found during examination due to other diseases.There was no statistically significant difference in the diameter of the left and right IVC(P=0.281).The left IVC merged with the left renal vein and then merged into the right IVC from front of abdominal aorta in 50 patients.The left IVC merged into the right IVC behind the abdominal aorta at about the third lumbar level below the renal vein in one case.The left IVC and left renal vein merged into the right IVC from behind the abdominal aorta in one case.And in a patient with complete visceral transposition,the two IVCs converged at the level of the 10th thoracic vertebra.Conclusion Double IVC can be clearly diagnosed by CT examination.Identification of double IVC malformation is of great significance in imaging diagnosis,retroperitoneal surgery and vascular intervention,and attention should be paid to individualized evaluation of special types of double IVC travelling.
