# Arteriovenous Fistula Simulating Deep Vein Thrombosis Following Lumbar Arthrodesis

## TL;DR

A rare complication after lumbar surgery, an arteriovenous fistula, can mimic deep vein thrombosis, emphasizing the need for accurate diagnosis and imaging.

## Contribution

Highlights a rare post-surgical complication that can be mistaken for a common condition, stressing the importance of differential diagnosis.

## Key findings

- Arteriovenous fistulas can present similarly to deep vein thrombosis after lumbar arthrodesis.
- Accurate imaging is crucial for distinguishing between these conditions and ensuring timely management.

## Abstract

Teaching point: Although deep vein thrombosis is a common concern after lumbar arthrodesis, rare complications such as an iatrogenic arteriovenous fistula can present similarly, highlighting the importance of a broad, differential diagnosis and appropriate imaging for timely management.
