Inclusion Criteria

Patients with arteriovenous malformations and indication for sclerotherapy
- Arteriovenous malformation can occur in a variety of ways anywhere on the body, but for our study only those vascular malformations are accessible that are located on the outside of the body and have a sufficient area for sonographic examination (about 5x5cm).

Exclusion Criteria

- Patients with arteriovenous malformations that are difficult accessible for an ultrasound examination ( for example oral AVM)
- AVM-Patients without medical indication for sclerotherapy
- Missing informed consent

• Study Type: observational
• Study Design: Not specified
