摘要

左侧下腔静脉转位是在复杂的胚胎发育过程中形成的一种罕见的解剖变异。我们报告了一位71岁的女性患者,在胃肠道出血检查期间,在对比增强计算机断层扫描中偶然发现了左侧下腔静脉。左侧下腔静脉形成半偶静脉-副半偶静脉延续。观察到右主动脉后肾静脉狭窄,符合胡桃夹子现象。左侧下腔静脉栓塞,虽然在大多数情况下无症状,但可能成为诊断混乱的来源或导致下肢深静脉血栓形成,特别是在年轻患者中。必须谨慎行事,以建立一个全面的诊断,并尽量减少手术风险。

Hemiazygos-accessory hemiazygos continuation of left-sided inferior vena cava: A case report and review of the literature
Left side transposition of the inferior vena cava (IVC) is a rare anatomical variation formed during its complex embryonic developmental process. We present a 71-year-old female patient with an incidentally identified left-sided IVC in contrast-enhanced computed tomography during gastrointestinal bleeding workup. The left-sided IVC formed a hemiazygos-accessory hemiazygos continuation. A narrowing of the right retroaortic renal vein, consistent with the nutcracker phenomenon, was observed. Left-sided IVC, although asymptomatic in the majority of cases, may act as source of diagnostic confusion or contribute to deep vein thrombosis of lower extremities, especially in younger patients. Care must be practiced to establish a comprehensive diagnosis and minimize procedural risks.
