uterine artery embolization
Also written as: UAE — uterine artery embolization
A minimally invasive interventional radiology procedure that blocks blood flow to uterine fibroids, causing them to shrink.
Full Definition
Uterine artery embolization (UAE) is a fertility-preserving treatment option for symptomatic uterine fibroids that involves selective catheterization of the uterine arteries and injection of embolic particles to occlude blood supply to the fibroids. The procedure is performed by interventional radiologists using fluoroscopic guidance, typically as an outpatient procedure under conscious sedation. Embolic materials commonly used include polyvinyl alcohol particles, tris-acryl gelatin microspheres, or gelatin sponge pledgets. UAE results in fibroid shrinkage of 20-60% within 6-12 months, with significant improvement in menorrhagia and bulk symptoms. The procedure is contraindicated in pregnancy and requires careful patient selection, particularly regarding future fertility desires. Post-embolization syndrome, characterized by pain, fever, and malaise, is common in the first week following the procedure.
Usage
Usage note: Commonly abbreviated as UAE in clinical documentation, but the full term should be used when first mentioned in formal reports.
