Arteriovenous Malformations

Focused Ultrasound Therapy

Clinical Trials SquareFocused ultrasound is an early-stage, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with arteriovenous malformations (AVMs). This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the body without damaging surrounding normal tissue. Where the beams converge, the ultrasound produces precise ablation (thermal destruction of tissue) enabling AVMs to be treated without surgery.

The primary options for treatment of AVMs includes surgery although some less invasive medicines or procedures can be chosen if the lesion is in a poor surgical location.

For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications and lower cost.

Advantages:

  • Focused ultrasound is noninvasive, so it does not carry added concerns like surgical wound healing or infection.
  • Focused ultrasound can reach the desired target without damaging surrounding tissue.
  • It can be repeated, if necessary.

Clinical Trials

At the present time, there are no clinical trials recruiting patients for focused ultrasound AVM treatments.

Regulatory Approval and Reimbursement

Focused ultrasound treatment for AVM is not yet approved by regulatory bodies or covered by medical insurance companies.
