AJR Teaching File: Profuse Vaginal Bleeding Seven Weeks Following Induced Abortion

摘要

In the clinical setting of vaginal bleeding, one can use clinical history and laboratory data to narrow the diagnosis and determine the best course of management before initiating imaging studies. For example, GTD and retained products of conception are conditions known to produce arteriovenous shunting that can be difficult to distinguish from uterine AVMs by imaging studies alone. However, these pregnancy-related entities can be diagnosed with the help of serum hCG measurements. Distinguishing between these conditions and uterine AVMs is critical because the latter can be treated safely and effectively with percutaneous transcatheter embo-lization but may be complicated by surgical intervention and curettage with heavy, even life-threatening, bleeding [1, 2].
