# Severe complications following transarterial microembolization for a micro arterio-venous fistula in a patient with chronic venous ulcer: a case report

## TL;DR

A patient with a chronic venous ulcer experienced severe complications after a TAME procedure for a micro arterio-venous fistula, emphasizing the need for careful patient selection.

## Contribution

First documented severe adverse event following TAME for a micro arteriovenous fistula in a patient with a chronic venous ulcer.

## Key findings

- The patient developed extensive leg swelling and skin changes after the TAME procedure.
- Prolonged inpatient care was required due to complications like cellulitis.
- The case highlights the importance of embolic agent selection and patient screening.

## Abstract

Transarterial microembolization (TAME) has gained recognition as a minimally invasive treatment for chronic musculoskeletal pain, demonstrating significant efficacy with a favorable safety profile (
1, 2). However, complications remain underreported. This case report describes the first documented severe adverse event in a patient with a chronic venous ulcer undergoing TAME for a micro arteriovenous fistula (AVF). The patient developed significant complications, including extensive leg swelling, skin changes, and cellulitis requiring prolonged inpatient care. These findings highlight the importance of patient selection and embolic agent considerations to mitigate potential risks associated with TAME.
