Acquired uterine arterio-venous malformation post molar pregnancy suction-curettage: 2 case reports

Introduction

Acquired uterine AVM is an abnormal and non-functional connection between uterine arteries and veins. It is reported as a consequence of uterine trauma as curettage procedures, pelvic surgery.

Cases presentation

The authors report 2 cases of uterine AVM post suction-curettage procedure on molar pregnancy incidentally discovered in ultrasound screening in the usual follow-up of this disease, diagnosed in the Department of Maternity of Mother and Child University Hospital Abderrahim Harouchi of Casablanca.

Clinical discussion

Uterine AVMs are extremely rare and should be considered in cases of heavy and persistent uterine bleeding. Uterine AVMs are either acquired or, more rarely, congenital, due to abnormal differentiation of the primary vascular structures during embryogenesis. The invasive technique allows confirmation of the diagnosis and identification of the major feeding vessels when embolization may be indicated as a treatment option.

Conclusion

Acquired uterine arteriovenous malformation is the result of uterine trauma; it presents as uterine bleeding through the vagina that can be life threatening, the rarity of the condition makes it difficult to diagnose, however the evolution of investigative techniques helps in the diagnostic process.

•

Arteriovenous malformation (AVM) also called arteriovenous fistula is a short circuit between an organ’s arterial and venous circulation.

•

Acquired arteriovenous malformations are often consequences of uterine trauma

•

They are also associated with infection, retained product of conception, gestational trophoblastic disease

•

Uterine artery embolization remains the treatment of choice for AVMs for patients who wish to preserve their fertility.
