A groundbreaking treatment: TESLA 

For many children with severe midaortic syndrome (MAS) and/or renovascular hypertension (RVH), the most effective approach is replacing the damaged blood vessels with healthy vessels near the aorta. However, this has been difficult in the past because the healthy vessels tend to be too short to adequately "fill in" for the vessels they are replacing.

TESLA 

Responding to this challenge, Boston Children's Hospital experts have designed a new treatment called Tissue Expander Stimulated Lengthening of Arteries (TESLA).

  • TESLA is based on a known scientific phenomenon, stretch-induced growth. This means that, when bodily tissue is stretched slowly and continuously over time, it will keep growing in the direction of the stretching.

  • To start the TESLA procedure, surgeons place a tissue-expanding device behind the child's aorta.

  • Next, the tissue-expanding device is gradually filled with saline solution over a period of several months. This slowly stretches the aorta and its blood vessels.

  • Throughout the stretching period, doctors monitor the function and well-being of the aorta and its neighboring organs with blood tests, ultrasound and CT scans.

  • Once the aorta appears to be long enough, surgeons remove the narrowed area and replace it with the newly stretched vessels.

TESLA is a very new procedure that we are still studying closely. But the initial results are very encouraging, and we hope to use this major advance to make a difference for many other patients in the future.

We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them. Thanks to you, Boston Children's is a place where we can write the greatest children's stories ever told.”
