Endovascular embolization for managing a massive shoulder arteriovenous malformation

Abstract

Arteriovenous malformations (AVMs) are congenital high flow pathologic linkages between arteries and veins of different sizes that may occur in any part of the body. The clinical presentation is largely dependent on the size and location of AVMs and can range from an asymptomatic birthmark to congestive heart failure in extreme cases. In this report, we describe a 20-year-old male who presented with a large AVM of the right shoulder that resulted in significant cosmetic and physical impairment and treated with several sessions of endovascular embolization with good clinical outcomes. This case highlights the complexity of diagnosing and managing these AVMs. Most of these anomalies require a multi-disciplinary approach that integrates both trans-catheter and surgical interventions with trans-arterial lesion embolization being the cornerstone of the treatment.

Shoulder Pain Associated With Multiple Arteriovenous Malformations Successfully Treated With Embolization

“…With such an incalculable behavior pattern, AVMs are difficult to diagnose, manage, and treat. The abnormality between the venous and arterial circulation results in altered blood pressure [ 3 , 19 ].…”
