Jennifer Matthews: Theresa Subalusky's reunion with Doctor Ted Chambers is a happy one, but their initial meeting in the ER was much more subdued.

Theresa Subalusky: A lot of pain and I couldn't stand it.

Jennifer Matthews: These x-rays show the tumor that was pushing on a vein and causing blood clots in her legs.

Theresa Subalusky: He took a picture of my leg because he never saw one the size of mine with a clot in it. It was just, they tell me, filled with a lot of clots.

Dr. Ted Chambers: Her legs were massively swollen and painful, very uncomfortable.

Jennifer Matthews: If the clots weren't removed quickly, Theresa could have long term complications. Doctor Chambers used a new device called Angiojet. It works like a small, controlled tornado inside the blood vessels.

Dr. Ted Chambers: We actually put a tiny catheter about the size of this cable into the vein back behind the knee on both sides and ran them all the way up here into the abdomen to dissolve the clot, and we use Angiojet to remove clots as well.

Jennifer Matthews: It creates a powerful suction, turning the catheter into a mini vacuum cleaner sucking out the blood clots.

Theresa said she noticed an improvement immediately after the procedure.

Theresa Subalusky: I can walk on it. I can stand on it. I can jump. I can do anything.

Jennifer Matthews: This is Jennifer Matthews reporting.
