## TL;DR

This paper presents a case of IVC obstruction caused by membranous blockage and highlights the role of advanced imaging and intravascular ultrasound in diagnosis and treatment.

## Contribution

Demonstrates the utility of intravascular ultrasound in diagnosing and managing membranous IVC obstruction.

## Key findings

- A 66-year-old woman had IVC obstruction due to septate membranes.
- Membranotomy with balloon angioplasty successfully treated the obstruction.
- Intravascular ultrasound was critical for diagnosis and procedural guidance.

## Abstract

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.

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.

We discuss our diagnostic approach and highlight the utility of intravascular ultrasound in making a clinical diagnosis and in guiding management.
