Focused Ultrasound Therapy
Focused 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.
How it Works
The mechanism of action that is being studied is thermal ablation of the AVM, which has been done on the extremity of a patient. There is also some preclinical work looking at using a mechanical (non-thermal) ablation on the malformation.
Advantages
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 – such as like surgical wound healing or infection – at a lower cost. Focused ultrasound can reach the desired target without damaging surrounding tissue, and 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.
