What is the most common indication for selective uterine artery angiography?

Selective uterine artery angiography is most commonly indicated during the embolization of symptomatic fibroids. This procedure is specifically designed to reduce or eliminate symptoms caused by uterine fibroids, such as heavy menstrual bleeding and pelvic pain. By performing the angiography, the interventional radiologist can accurately visualize the uterine arteries and determine the best approach for embolization, effectively cutting off the blood supply to the fibroids, leading to their shrinkage and the alleviation of symptoms.

This procedure highlights the significant role of angiography in the management of uterine fibroids, distinguishing it from other options where angiography may not be the primary or most critical step in the intervention process. While malignancy, trauma, and situations during hysterectomy might involve selective uterine artery angiography, they are not as prevalent as in the context of treating symptomatic fibroids, making the use of angiography most relevant in that scenario.
