Introduction: Uterine AVM, a rare vascular condition affecting 1 in 1,000 to 1 in 3,000 women, involves abnormal connections between uterine arteries and veins, often presenting as abnormal uterine bleeding. Aims and objectives: This study aims to provide an overview of the diagnostic processes and treatment strategies for uterine AVMs, focusing on imaging techniques, clinical implications, treatment options, multidisciplinary care, and follow-up recommendations to improve patient outcomes and overall understanding of the condition. Materials and methods: A multidisciplinary team, including obstetricians, gynecologists, radiologists, and anesthetists, managed a 31-year-old G3P2+0 patient with vaginal bleeding presenting as incomplete abortion. Diagnostic approaches included Doppler ultrasound and CT angiography to identify AVM. Treatment involved balloon tamponade, hormonal therapy (leuprolide) and endovascular embolization as interventions. Hysterectomy was performed after unsuccessful embolizations. Post-operative care focused on monitoring for complications. Outcome measures included symptom improvement, resolution of abnormal bleeding, and enhanced quality of life. Results: In this case study of a uterine arteriovenous malformation (AVM), accurate diagnosis was achieved through imaging techniques, including color Doppler ultrasound and CT angiography. The patient presented with potentially life-threatening vaginal bleeding and anemia, prompting further investigation. Color Doppler ultrasound revealed retained products of conception and features of the AVM, while the CT angiogram showed markedly dilated arterial branches and venous channels in the uterine fundus. After two unsuccessful uterine artery embolization sessions, hysterectomy was ultimately performed. Conclusion: This case highlights the critical need for prompt recognition and management of uterine arteriovenous malformations (AVMs), which can lead to significant morbidity if untreated. Accurate diagnosis through imaging allowed for timely intervention. Increased awareness among healthcare providers is essential, particularly for patients with unexplained heavy bleeding or anemia. A comprehensive evaluation and multidisciplinary approach are vital for navigating the complexities of this condition, ultimately ensuring improved patient outcomes.
