Area of Science:

  • Interventional Radiology
  • Neuromodulation
  • Medical Devices

Background:

  • Pathologic conditions can be managed by interrupting neural signaling.
  • Current treatments include implantable neuromodulation or surgical neural ligation.
  • Percutaneous device-mediated cryoneurolysis presents an alternative approach.

Purpose of the Study:

  • To investigate computed tomography-guided cryovagotomy for managing mild to moderate obesity.
  • To attenuate hunger signals by targeting the posterior vagal trunk.

Main Methods:

  • Computed tomography (CT)-guided cryoablation using a needle.
  • Targeting the posterior vagal trunk.
  • Based on experience with surgical and electrical vagotomy.

Main Results:

  • Computed tomography-guided cryovagotomy is under investigation for obesity management.
  • The procedure aims to reduce hunger signals.

Conclusions:

  • Percutaneous, image-guided cryoneurolysis holds potential for various clinical challenges.
  • Further investigations will expand the application of this technique.
