Post-Traumatic Arteriovenous Fistulas Leading to Heart Failure.


ABSTRACT:

Introduction

The detection of acquired arteriovenous fistulas (AVFs) is mostly incidental. However, the modification of haemodynamic conditions secondary to AVFs can lead to dramatic systemic complications, including cardiac complications. In this report, two unusual cases of congestive heart failure secondary to acquired AVF are presented.

Report

A 40 year old man with past history of gunshot wound of the right flank complained of severe right limb swelling and shortness of breath. An AVF between the right external iliac artery and external iliac vein responsible for the cardiac failure was diagnosed. A 40 year old woman with past history of spinal surgery complained of breathlessness and lower limb oedema. She presented with recurrent episodes of ascites and dyspnoea. An AVF between the right common iliac artery and the common iliac vein responsible for high output cardiac failure was diagnosed. Open surgery was performed in both patients and treatment of the AVFs led to the resolution of all symptoms. Follow up at four and three years, respectively, was uneventful in both cases.

Discussion

Although rare, heart failure secondary to an AVF can be encountered. These rare cases highlight the significance of careful inquiry into the patient's medical history and meticulous follow up physical examinations for patients with injuries in close proximity to vessels.
