BACKGROUND
Inferior vena cava (IVC) obstruction is an underdiagnosed clinical entity. Recognizing obstruction of the IVC can be challenging due to its insidious and often subclinical presentation.
CASE SUMMARY
A 66-year-old woman presented with chronic bilateral lower extremity swelling. An evaluation revealed septate membranes within the IVC that were causing IVC obstruction. This was successfully treated with membranotomy using balloon angioplasty.
REVIEW
We discuss our diagnostic approach and highlight the utility of intravascular ultrasound in making a clinical diagnosis and in guiding management.
背景
下腔静脉（IVC）梗阻是一种诊断不足的临床病症。由于其隐匿性且常为亚临床表现，识别下腔静脉梗阻具有挑战性。
病例摘要
一名66岁女性因双侧下肢慢性肿胀就诊。评估发现下腔静脉内有分隔膜，导致下腔静脉梗阻。通过球囊血管成形术进行膜切开术成功治疗了该病症。
综述
我们讨论了诊断方法，并强调了血管内超声在临床诊断和指导治疗中的作用。
