Uterine artery embolization: an effective treatment for intractable obstetric haemorrhage
1Department of Radiology, Taipei Veterans General Hospital, Taipei, Taiwan, ROC.
Aim:
To present the findings of uterine artery embolization (UAE) in the management of obstetric haemorrhage.
Materials And Methods:
From October 1999 to February 2003, 10 women with postpartum haemorrhage (n=7) and post-abortion haemorrhage with placenta accreta (n=3), were referred to our department for pelvic angiography and possible arterial embolization.
Results:
Angiography revealed engorged and tortuous uterine arteries in all patients; and contrast medium extravasation in three patients. Eight patients (three with and five without detectable active bleeding) then underwent bilateral UAE. Medium-sized (250-355 microm) polyvinyl alcohol particles were injected via a coaxial catheter into the uterine arteries, followed by gelatin sponge pieces via a 4F Cobra catheter. Microcoil devascularization was also performed in the two patients with visible, active bleeding. The vaginal bleeding resolved in all patients, without any ischaemic complications. At follow-up, all patients who underwent UAE had normal menstruation; three of them subsequently gave birth to full-term healthy babies.
Conclusion:
Selective UAE by the coaxial method is safe and effective to control obstetric haemorrhage, with the potential to preserve fertility.
