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.
