Abstract
In this article, we comment on the paper by Kakinuma et al published recently. We focus specifically on the diagnosis of uterine pseudoaneurysm, but we also review other uterine vascular anomalies that may be the cause of life-threating hemorrhage and the different causes of uterine pseudoaneurysms. Uterine artery pseudoaneurysm is a complication of both surgical gynecological and non-traumatic procedures. Massive hemorrhage is the consequence of the rupture of the pseudoaneurysm. Uterine artery pseudoaneurysm can develop after obstetric or gynecological procedures, being the most frequent after cesarean or vaginal deliveries, curettage and even during pregnancy. However, there are several cases described unrelated to pregnancy, such as after conization, hysteroscopic surgery or laparoscopic myomectomy. Hemorrhage is the clinical manifestation and it can be life-threatening so suspicion of this vascular lesion is essential for early diagnosis and treatment. However, there are other uterine vascular anomalies that may be the cause of severe hemorrhage, which must be taken into account in the differential diagnosis. Computed tomography angiography and embolization is supposed to be the first therapeutic option in most of them.
