Overview

Case report shows high-output heart failure improvements in a male after fistula closure, indicating potential reversibility.

Key Points

  • To illustrate the cardiovascular consequences of chronic traumatic arteriovenous fistulas and their treatment.
  • Reported a case of a 41-year-old male with a decade-old traumatic AVF managed with endovascular repair.
  • Utilized echocardiography and invasive hemodynamic monitoring for preoperative assessment.
  • Followed postoperative recovery and outcomes over four months.
  • Preoperative cardiac output was 14.9 L/min; improved to 8.6 L/min after fistula closure.
  • Pulmonary artery pressures decreased from 33/20 mmHg to 22/15 mmHg postoperatively.
  • Iliac vein diameter reduced significantly from 8.7 cm to 6.2 cm during follow-up.
