Multimodal approach in distinguishing and managing uterine arteriovenous malformation: A case report

Abstract

Arteriovenous malformations (AVMs) are abnormal vascular connections bypassing the capillary system, categorized as acquired or congenital. Acquired uterine AVMs, often resulting from uterine trauma due to procedures like dilatation and curettage, can be life threatening, necessitating prompt diagnosis and management. Here we present a 34-year-old woman with a history of missed abortion and dilatation and curettage presenting with abnormal uterine bleeding 2 months postprocedure. Although initial transvaginal ultrasound suggested retained products of conception, several modalities were required to accurately diagnose uterine AVM with invasive angiography revealing the culprit vessel. Multimodal imaging approaches are crucial for accurate diagnosis and treatment. This case highlights the importance of prompt and precise management to prevent severe outcomes and maintain fertility, emphasizing the need for continued research to improve treatment strategies.
