RESUMO

Paciente de 37 años que acudió a urgencias por metrorragia, G3P1A2, el último de ellos un aborto tardío en gestación gemelar monocorial biamniótica de 20 semanas hacía dos meses. En la ecografía destaca en zona miometrial un área de marcada vascularización de 67 x 45 mm. Tras descartar proceso residual gestacional y ante la sospecha de malformación arteriovenosa uterina se solicitó resonancia magnética nuclear y angiotac, tras confirmar la malformación vascular se programó para embolización de ambas arterias uterinas con el fin de preservar la fertilidad.


A 37-year-old patient came to the emergency due to metrorrhagia, G3P1A2, the last of them a late abortion in a 20 weeks monochorionic diamniotic twin pregnancy two months ago. Ultrasound revealed an intramiometrial area of 67 x 45 mm with increased vascularization area. A diagnosis of an arteriovenous malformation was considered. In order to confirm the diagnosis pelvic magnetic resonance and angiogram was performed. Once the vascular malformation was confirmed the patient was scheduled for transcatheter arterial embolization in order to preserve fertility.

RESUMO

Las malformaciones vasculares uterinas son muy infrecuentes y se presentan asociadas a metrorragia con riesgo vital. Su incidencia no es conocida porque las series son de pocos casos. Presentamos tres pacientes con hemorragia obstétrica cuyo estudio diagnóstico con ultrasonido y angiografía, demostró malformación arteriovenosa uterina. En un caso, dada la extensión de la lesión, el tratamiento fue con embolización bilateral de arterias uterinas seguida de histerectomía. Otras dos pacientes, por preservación de fertilidad, fueron sometidas solo a embolización. La evolución clínica y las imágenes confirmaron que los procedimientos fueron exitosos. Se discute la importancia de la interpretación correcta de las imágenes para el diagnóstico, la adaptación de los métodos terapéuticos al caso individual y el manejo multidisciplinario.


The uterine vascular malformations are very infrequent and associated to maternal hemorrhage with vital risk. The incidence is unknown because the published series are little with few cases. We described three cases with obstetrical hemorrhage and the image study with ultrasound and angiography showed an arteriovenous malformation. One patient, for the extensive lesion, was treated with bilateral embolization of uterine arteries and then, histerectomy. The others patients, for preservation her fertility, were treated with embolization only. The clinical evolution and the vascular images study confirm the success of the procedures. We discuss the importance of images analysis for the diagnosis, the individual application of therapeutic methods and a multidisciplinary approach for this scope.

RESUMO

Presentamos el caso de una embarazada con placenta ístmica, percreta, previa central, con extensas anastomosis vasculares y flujo de alta velocidad. En la resolución mediante cesárea-histerectomía, para prevenir la hemorragia intraoperatoria, se utilizó una intervención radiológica en secuencia de oclusión temporal de las ilíacas internas, embolización de las arterias uterinas, reposicionamiento e insuflación de balones en ilíacas comunes. Se logró mantener estabilidad hemodinámica y el control del sangrado; estando ocluida la circulación uterina hubo pérdidas moderadas en la parte final de la operación. Se discuten la característica poco común de la implantación y percretismo ístmico, y el beneficio del uso combinado de la oclusión vascular con la cirugía expedita para minimizar el riesgo materno.


We present a patient with placenta previa percreta and oclusive. It had extensive vascular anastomosis with high velocity flow, in which resolution by cesarean-hysterectomy was done for bleeding control and followed by temporal occlusion of iliac arteries, embolization of uterine arteries, reposition and insuflation of balloons in common iliac arteries. The patient was stable and moderated bleeding happened to the end of intervention when the uterine arterial circulation was occluded. We discuss the uncommon of isthmic implantation and percretism and the benefits of both vascular occlusion and expedite surgery for to minimize maternal compromise or damage.

RESUMO

The approach to symptomatic uterine fibroids has seen a marked evolution in recent years thanks to the emergence of minimally invasive techniques that allow for uterine preservation. Selective uterine artery embolization (UAE) consists of the complete occlusion of the 2 uterine arteries with embolic particles in order to produce ischemic necrosis of the fibroids without permanently affecting the normal uterine tissue. This technique significantly reduces the amount of bleeding and causes a reduction in uterine volume at 3 months postprocedure, which is maintained over time, allowing for 70% of patients to avoid surgery. Moreover, UAE entails shorter surgical times, reduced hospital stays and fewer days needed to return to work when compared with traditional surgical techniques (hysterectomy and fibroidectomy), without any differences in the quality-of-life scales at 5 years. UAE should therefore be included in the therapeutic options offered to patients with symptomatic fibroid uteri.
