摘要
目的 通过回顾下腔静脉的胚胎发育特征、分析其临床CT表现,提高对下腔静脉先天变异CT表现的认识。方法 回顾性收集2015年1月至2020年10月因各种原因于本院行腹部CT平扫及增强扫描或者胸腹部联合CT检查,于门静脉期或延迟期观察下腔静脉的走形及连接,回顾性学习下腔静脉的胚胎发育特征,分析本组病例下腔静脉先天变异的类型、特征以及是否合并其他脏器畸形。结果 本组27例患者,下腔静脉肝段缺如10例,双下腔静脉8例,左位下腔静脉10例,下腔静脉异常延续12例,其中部分病例为几种变异联合存在;本组未收集到下腔静脉后输尿管病例。下腔静脉发育异常合并其他系统异常,共12例(12/27),其中6例合并先天性心脏病,另6例分别合并迷走右锁骨下动脉及夹层、永存左上腔静脉、多脾综合征、脾静脉与肠系膜上静脉汇合异常;其他15例下腔静脉异常是因其他原因行CT检查偶然发现。结论 识别下腔静脉变异对临床操作及治疗具有重要意义;因此,对影像诊断医生而言下腔静脉的观察与评价应该成为日常诊断工作中的基本组成部分。
Objective To improve the recognition of congenital variation of inferior vena cava, by reviewing the embryonic development characteristics of the inferior vena cava, and analyzing the clinical CT manifestations. Methods Retrospectively collected the patients in January 2015 to October 2020 examined by CT on the line for various reasons. All patients were examined with abdominal or joint chest CT scan and enhanced scan. Retrospectively study the embryonic development features of inferior vena cava, analyze the incidence of congenital variation types and whether inferior vena cava merge other organs deformity. Results In the group of 27 cases, there are 10(10/27) cases of the absence of IVC hepatic segment, 8(8/27) cases for double inferior vena cava, 10(10/27) cases with the left inferior vena cava, 12(12/27) cases for abnormal continuation for chest vein. This group did not collected cases with the ureter after inferior vena cava. There are 12(12/27) cases of congenital IVC variants merging other system deformity, which include 6 cases of congenital heart disease and 6 cases respectively for the right subclavian artery, persistent left superior vena cava, polysplenia syndrome, and so on. Another 15(15/27) cases are discovered by accident on CT examination for other reasons. Conclusion There are great significance of identification of inferior vena cava variation on clinical operation and treatment. Therefore, observation and assessment of IVC should be a basic component of routine diagnostic observation model for radiologists.
