With a public who is largely unfamiliar with the work that interventional radiologists do, one woman is on a mission to educate others on the minimally invasive, image-guided procedure that saved her life, writes Huffington Post.

The otherwise healthy, active mother of four hadn’t been feeling well for a while before she landed in the emergency room with life-threatening blood clots in her lungs. “I had been complaining of abdominal thickness and low pelvic pain for months.” Then she developed “a very swollen left leg, shortness of breath and nausea.” The emergency room doctors knew she had a blood clot in her lungs, but they didn’t know why.

As a favor to a friend of Stephani’s, Interventional Radiologist Dr. Thomas Bey of Redding, California, took one look at her images and suspected a deeper cause: May-Thurner Syndrome. And he was correct.
