Background:Arteriovenous malformation is a rare condition during pregnancy, so the bleeding disorders are. Literature shows only case reports about these two simultaneaous conditions.

Case Report: 30 years old primigravid patient is admitted to labour with fetal delayed intrauterine growth . Previously diagnosed with congenital deficit of coagulation factors V and VII and a partially embolized arteriovenous malformation (AVM). 
After a multidisciplinary assesment we decided to perform an elective cesarian section in order to prevent valsalva manouvers and having in mind the fact that neuroaxial procedures are contraindicated due to the patients hematological disorder.
Elective C-section was performed under general anesthesia and standard monitorization after previous factor VII replacement and a multiple dose of tranexamic acid. No increased blood loss was recorded, anesthetic eduction was uneventfull and neurological postoperative assessment was normal.
The patient and the newborn were discharged without any complications at third day.

Discussion:Few evidence is available about the correct management of AVM and haematologycal dyscrasia during pregnancy, wether vaginal delivery or elective C section is prefered for the patients carrying a AVM is still unknown.

Because of small samples and sparse data about the treatment of AVM rupture during pregnancy and puerperium, the management of these patients is very difficult and controversial.
